AMVAC

ANSI

The AMVAC is truly the next generation medium voltage vacuum circuit breaker, utilizing magnetic actuation technology to provide a more reliable and longer lasting solution to the industry. This is made possible by the simplicity of the magnetic actuators design features such as one moving part and built in safety features. (ANSI C37.04-C37.06-C37.09) Summary of benefits: − High duty breaker 1,200 A to 3,000 A continuous current and 25 kA to 50 kA interrupting − Proven design since 2003 using a magnetic actuator operating mechanism with one moving part, built in open/close coils and no maintenance on the operating mechanism. − Switching operations are achieved by exciting one of the two coils which shifts the flux density and causes a force that exceeds the retaining force of the permanent magnets − Current to the actuator open and close coils is time limited to approximately 45ms, thus eliminating the possibility to burn up coils common in spring actuated mechanisms. − Capacitor charging, switching, anti-pumping, interlocking, under voltage release, and armature position details incorporated by an electronic controller − First developed by ABB over 20 years ago, the vacuum interrupters are fully embedded in solid insulation material to provide superior protection against dust, dirt, and condensation, while being less susceptible to failure due to contamination, tracking, or partial discharge. − Reduced ownership costs through minimal maintenance, reduced downtime, smaller battery banks, lower parts inventory, and a standard 5-year warranty − The increased maintenance cycle associated with magnetic actuation increases safety as a result of less time for personnel in switchgear compartments. − The racking mechanism (truck) is integrated into the breaker and designed to 180 ft∙lb torque rating to provide increased reliability and reduced maintenance costs.

VM1

IEC

ANSI

The VM1 is truly the next generation small footprint medium voltage vacuum circuit breaker, utilizing magnetic actuation technology to provide a more reliable and longer lasting solution to the industry. This is made possible by the simplicity of the magnetic actuators design features such as one moving part and built in safety features. The VM1 provides a smaller footprint solution for magnetic actuation type circuit breakers. (IEC 62271-100, ANSI/IEEE C37.04-C37.09-C37.54-C37.55)

Revolutionary magnetic actuator that drives the AMVAC and VM1 breakers

14 Medium voltage indoor circuit breakers | Descriptive bulletin

Summary of benefits: − High duty breaker 630 A to 3,150 A continuous current and 16 kA to 31.5 kA interrupting − Available in ANSI markets at 15 kV, 1,200 A and 2,000 A continuous current and 25 kA and 31.5 kA interrupting − Small footprint design ideal for industries where space is at a premium with widths as low as 17.7 in (450 mm) for fixed breakers and 24 in (600 mm) for withdrawable breakers within a Powercube module − Proven design since 2003 using a magnetic actuator operating mechanism with one moving part, built in open/close coils and no maintenance on the operating mechanism. − Switching operations are achieved by exciting one of the two coils, which shifts the flux density, and causes a force that exceeds the retaining force of the permanent magnets − Current to the actuator open and close coils is time limited to approximately 45ms, thus eliminating the possibility to burn up coils common in spring charge mechanisms. − Capacitor charging, switching, anti-pumping, interlocking, under voltage release, and armature position details incorporated by an electronic controller − First developed by ABB over 20 years ago, the vacuum interrupters are fully embedded in solid insulation material to provide superior protection against dust, dirt, and condensation, while being less susceptible to failure due to contamination, tracking, or partial discharge. − Reduced ownership costs through minimal maintenance, reduced downtime, smaller battery banks, and lower parts inventory − The increased maintenance cycle associated with magnetic actuation increases safety as a result of less time for personnel in switchgear compartments. − The racking mechanism (truck) is integrated into the breaker and designed to 180 ft∙lb torque rating to provide increased reliability and reduced maintenance costs

Descriptive bulletin | Medium voltage indoor circuit breakers 15

eVD4

IEC

The eVD4 circuit breaker is a complete packaged medium voltage electrical plant protection system. It is the evolution of the traditional concept of a circuit breaker providing breaking, measurement, protection, control, and communication functions in a single device. The eVD4 circuit breaker also integrates combined current and voltage sensors reducing the amount of compartments required in a switchgear line-up. This makes eVD4 the ideal solution for all installations where a high degree of continuity of service is required, along with low footprint requirements. (IEC 62271-100) Summary of benefits: − High duty breaker 630 A to 2,500 A continuous current and 16 kA to 40 kA interrupting − eVD4 is mechanically interchangeable with the VD4, VMax, and VM1 series circuit breakers − Less time required for engineering, wiring in the low voltage compartments, and for the final testing procedures due to the built in protection and control unit that includes current and voltage sensors − Combined with RBX615 relay from the Relion family, the eVD4 system takes advantage of the most reliable technologies − Mean Time to Repair of systems incorporating eVD4 is much shorter than systems with conventional breakers − First developed by ABB over 20 years ago, the vacuum interrupters are fully embedded in solid insulation material to provide superior protection against dust, dirt, and condensation, while being less susceptible to failure due to contamination, tracking or partial discharge. − Modular design with common parts across ABB Low & Medium Voltage, high & low duty, and ANSI & IEC breakers allows for greater reliability and maintainability

HD4

IEC

HD4 medium voltage circuit breakers use SF6 gas to extinguish the electric arc and as the insulating medium. Interrupting in SF6 gas takes place without any arc chopping or generation of overvoltages. These characteristics ensure long electrical life of the circuit breaker and limited dynamic, dielectric, and thermal stresses on the installation. Not to mention, the light and compact structure of the circuit breaker ensures great sturdiness and excellent mechanical reliability at a great value. (IEC 62271-100) Summary of benefits: − High duty breaker 630 A to 4,000 A continuous current and 16 kA to 50 kA interrupting − Autopuffer breaking technique used in high voltage breakers minimizes arc times − Soft quenching technique eliminates chopping currents and is free of re-strike and re-ignition − Mechanical and electrical safety locks prevent incorrect operations, while increasing safety − Spring charged ESH mechanical operating mechanism with standard anti-pumping device − Maintenance-free epoxy embedded poles sealed for life and tested with Helium to ensure no possibility of SF6 leakage

1. Description

The new VD4 are a synthesis of renowned technology in designing and constructing vacuum interrupters embedded in poles, and excellency in design, engineering and production of circuit-breakers. The VD4 medium voltage circuit-breakers use vacuum interrupters embedded in the poles. This construction technique makes the circuit-breaker poles particularly sturdy and protects the interrupter from impacts, dust deposits and humidity. The vacuum interrupter houses the contacts and makes up the interrupting chamber.

Current interruption in vacuum The vacuum circuit-breaker does not require an interrupting and insulating medium. In fact, the interrupters do not contain ionisable material. In any case, on separation of the contacts an electric arc is generated made up exclusively of melted and vaporised contact material. The electric arc remains supported by the external energy until the current is cancelled in the vicinity of natural zero. At that instant, the rapid reduction in the load density carried and the rapid condensation of the metallic vapour, leads to extremely rapid recovery of the dielectric characteristics. The vacuum interrupter therefore recovers the insulating capacity and the capacity to withstand the transient recovery voltage, definitively extinguishing the arc. Since high dielectric strength can be reached in the vacuum,

• Vacuum interruption technique • Vacuum contacts protected against oxidation and contamination • Vacuum interrupter embedded in the pole • Interrupter protected against shocks, dust and humidity • Operation under different climatic conditions • Limited switching energy • Stored energy operating mechanism with anti-pumping device supplied as standard • Simple customisation with a complete range of accessories • Fixed and withdrawable version • Compact dimensions • Sealed-for-life poles • Sturdiness and reliability • Limited maintenance • Circuit-breaker racking in and racking out with door closed • Incorrect and hazardous operations are prevented thanks to special locks in the operating mechanism and in the truck • High environmental compatibility

even with minimum distances, interruption of the circuit is also guaranteed when separation of the contacts takes place a few milliseconds before passage of the current through natural zero. The special geometry of the contacts and the material used, as well as the limited duration and low voltage of the arc, guarantee minimum contact wear and long life. Furthermore, the vacuum prevents their oxidation and contamination. Operating mechanism The low speed of the contacts, together with the reduced run and low mass, limit the energy required for the operation and therefore guarantee extremely limited wear of the system. The circuit-breaker therefore only requires limited maintenance. The VD4 circuit-breakers use a mechanical operating

mechanism, with stored energy and free trip. These characteristics allow opening and closing operations independent of the operator. The operating mechanism is of simple conception and use and can be customised with a wide range of accessories which are easy and rapid to install. This simplicity converts into greater reliability of the apparatus. The structure The operating mechanism and the poles are fixed to a metal frame which is also the support for the fixed version of the circuit-breaker. The compact structure ensures sturdiness and mechanical reliability. Apart from the isolating contacts and the cord with plug for connection of the auxiliary circuits, the withdrawable version is completed with the truck for racking it into and out of the switchgear or enclosure with the door closed.

1. Description

Quenching principle of ABB interrupters In a vacuum interrupter, the electric arc starts at the moment of contact separation and is maintained until zero current and can be influenced by magnetic fields. Vacuum arc – diffuse or contracted Following contact separation, single melting points form over the entire surface of the cathode, producing metal vapours which support the arc. The diffuse vacuum arc is characterised by expansion over the contact surface and by an even distribution of thermal stress on the contact surfaces.

At the rated current of the vacuum interrupter, the electric arc is always of the diffuse type. Contact erosion is very limited and the number of current interruptions very high. As the interrupted current value increases (above the rated value), the electric arc tends to be transformed from the diffuse into the contracted type, due to the Hall effect. Starting at the anode, the arc contracts and as the current rises further it tends to become sharply defined. Near the area involved there is an increase in temperature with consequent thermal stress on the contact. To prevent overheating and erosion of the contacts, the arc is kept rotating. With arc rotation it becomes similar to a moving conductor which the current passes through.

Schematic diagram of the transition from a diffuse arc to a contracted arc in a vacuum interrupter.

The spiral geometry of ABB vacuum interrupter contacts The special geometry of the spiral contacts generates a radial magnetic field in all areas of the arc column, concentrated over the contact circumferences. An electromagnetic force is self-generated and this acts tangentially, causing rapid arc rotation around the contact axis. This means the arc is forced to rotate and to involve a wider surface than that of a fixed contracted arc.

Apart from minimising thermal stress on the contacts, all this makes contact erosion negligible and, above all, allows the interruption process to be controlled even with very high short-circuits. ABB vacuum interrupters are zero-current interrupters and are free of any re-striking. Rapid reduction in the current charge and rapid condensation of the metal vapours simultaneously with the zero current, allows maximum dielectric strength to be restored between the interrupter contacts within microseconds.

Fields of application The VD4 circuit-breakers are used in power distribution for control and protection of cables, overhead lines, transformer and distribution substations, motors, transformers, generators and capacitor banks.

Standards The VD4 circuit-breakers comply with the IEC 62271-100, VDE 0671-part. 100, CEI EN 62271-100 file 7642 (20055) Standards and with those of the major industrialised countries. The VD4 circuit-breakers have undergone the tests indicated below and guarantee the safety and reliability of the apparatus in service in any installation. • Type tests: heating, withstand insulation at power frequency, withstand insulation at lightning impulse, short-time and peak withstand current, mechanical life, short-circuit current making and breaking capacity. • Individual tests: insulation of the main circuits with voltage at power frequency, auxiliary circuit and operating mechanism insulation, measurement of the main circuit resistance, mechanical and electrical operation.

Service safety Thanks to the complete range of mechanical and electrical locks (available on request), it is possible to construct safe distribution switchgear with the VD4 circuit-breakers. The locking devices have been studied to prevent incorrect operations and to inspect the installations whilst guaranteeing maximum operator safety. Key locks or padlock devices enable opening and closing operations and/or racking in and racking out. The racking-out device with the door closed allows the circuitbreaker to be racked into or out of the switchgear only with the door closed. Anti-racking-in locks prevent circuit-breakers with different rated currents from being racked in, and the racking-in and racking out operation with the circuit-breaker closed.

Standard fittings of withdrawable circuit-breakers for UniGear ZS1, ZS2 switchgear and similar panels The basic versions of the withdrawable circuit-breakers are three-pole and fitted with: – EL type manual operating mechanism – mechanical signalling device for closing springs charged/ discharged – mechanical signalling device for circuit-breaker open/closed – closing pushbutton – opening pushbutton – operation counter – set of ten circuit-breaker open/closed auxiliary contacts

– locking electromagnet in the truck (compulsory for ABB switchgear). This device prevents racking the circuit-breaker into the switchgear with the auxiliary circuits disconnected (plug not inserted in the socket) – door interlock (compulsory for ABB switchgear); this device prevents racking the circuit-breaker into the switchgear when the switchgear door is open.

Note: with the group of ten auxiliary contacts supplied as standard and the maximum number of electrical applications, three break contacts (signalling circuit-breaker open) and four make contacts (signalling circuit-breaker closed) are available.

– lever for manually charging the closing springs – isolating contacts – cord with connector (plug only) for auxiliary circuits, with striker pins which does not allow the plug to be inserted into the socket if the rated current of the circuit-breaker is lower than the rated current of the panel – racking-out/in lever (the quantity must be defined according to the number of pieces of apparatus ordered)

Standard fittings of withdrawable circuit-breakers for PowerCube modules The basic versions of the withdrawable circuit-breakers are always three-pole and fitted with: – EL type manual operating mechanism – mechanical signalling device for closing springs charged/ discharged – mechanical signalling device for circuit-breaker open/closed – closing pushbutton – opening pushbutton – operation counter – set of ten circuit-breaker open/closed auxiliary contacts

– racking-in/out lever (the quantity must be defined according to the number of pieces of apparatus ordered) – locking electromagnet in the truck. This prevents the circuit-breaker being racked into the panel with the auxiliary circuits disconnected (plug not inserted in the socket). – door interlock (compulsory for ABB switchgear); this device prevents racking the circuit-breaker into the switchgear when the switchgear door is open.

Note: with the group of ten auxiliary contacts supplied as standard and the maximum number of electrical applications, three break contacts (signalling circuit-breaker open) and four make contacts (signalling circuit-breaker closed) are available.

– lever for manually charging the closing springs – isolating contacts – cord with connector (plug only) for auxiliary circuits, with striker pin which does not allow the plug to be inserted into the socket if the rated current of the circuit-breaker is different from the rated current of the panel

2. Selection and ordering Optional accessories

The accessories identified with the same number are alternative to each other.

1 Shunt opening release (-MO1)

2 Additional shunt opening release (-MO2)

This allows remote opening control of the apparatus. The release can operate both in direct and alternating current. This release is suitable for both instantaneous and permanent service. In the case of instantaneous service, the minimum current impulse time must be 100 ms. Checking functionality and continuity is only possible using the STU device (accessory 21).

Like the shunt opening release described above, this allows remote opening control of the apparatus and can be supplied by a circuit completely separate from the release (-MO1). It keeps all the electrical and operating characteristics of the shunt opening release. Checking functionality and continuity is only possible using the STU device (accessory 21).

The opening solenoid (-MO3) is a special release with demagnetisation to be combined with an overcurrent protection relay of the self-supplied type. It is located in the operating mechanism (in the left side piece) and is not alternative to the additional shunt opening release (-MO2). It is not available for 40 and 50 kA circuit-breakers. Should the application of this accessory be required, specify the request at the time of order since subsequent application by the customer is not possible.

This allows remote closing control of the apparatus. The release can operate both in direct and alternating current. This release is suitable both for instantaneous and permanent service. In the case of instantaneous service, the minimum current impulse time must be 100 ms. Use of the permanently supplied release is recommended to carry out the electrical anti-pumping function. It keeps all the electrical and operating characteristics of the shunt opening release. Checking functionality and continuity is only possible using the STU device (accessory 21).

It can be used for remote trip (by means of normally closed type pushbuttons), lock on closing or to control the voltage in the auxiliary circuits. The circuit-breaker can only close with the release supplied (the closing lock is made mechanically). The release can operate both in direct and alternating current. Note As an alternative to the undervoltage release, an additional shunt opening release (-MO4) with the same electrical and operating specifications as shunt opening release (-MO1) can be installed on request. Warning! Installation of the additional shunt opening release (-MO4) requires a special mounting plate for releases. Moreover, application (-MO4) must be requested at the time of order and not afterwards.

8 Transient contact (-BB4)

9 Position contact (-BT3)

This contact closes momentarily (duration > 30 ms) on circuitbreaker opening controlled remotely with a shunt opening release. The indication is not provided when opening is manual and local. In fact, a contact (–BB11) is activated by the manual pushbutton and cuts off the transient contact closure (–BB4). The transient contact is activated directly from the main operating shaft when the indication is provided only on actual opening of the main circuit-breaker contacts.

This contact is used, together with the locking magnet in the operating mechanism (-RL1) to prevent remote closing during traverse into the unit. It is only supplied for the withdrawable version circuit-breakers for UniGear ZS1 switchgear and PowerCube modules. It cannot be supplied when the transmitted contacts are requested in the truck (-BT1; -BT2).

10 Transmitted contacts in the truck (-BT1; -BT2)

Transmitted contacts of the withdrawable circuit-breaker (installed in the circuit-breaker truck - only for VD4/P withdrawable circuit-breaker). These contacts are either in addition or as an alternative to the position contacts (for signalling circuit-breaker racked out) located in the unit. They also carry out the function of the position contact (-BT3).

11 Motor operator (-MS)

12 C ontact for signalling closing spring charged/ discharged (-BS2)

This carries out automatic charging of the circuit-breaker operating mechanism closing spring. After circuit-breaker closing, the geared motor immediately recharges the closing springs. In the case of a power cut or during maintenance work, the closing spring can be charged manually in any case (by means of the special crank handle incorporated in the operating mechanism).

This consists of a microswitch which allows remote signalling of the state of the circuit-breaker operating mechanism closing pring. The following signals are possible: – contact open: signalling spring charged – contact closed: signalling spring discharged. The two signals must be used for circuits which have the same power supply voltage.

21 STU Shunt Test Unit

Due to the particular construction of these releases, checking the functionality of the shunt closing (-MC) and opening (-MO1, -MO2) releases is not possible with dedicated relays (e.g. TCS Test Control Supervision, CCC Control Coil Continuity) or with the REF control and protection unit. The only device able to carry out a check of the functionality is the STU device. Please contact us if you want to carry out this control with devices other than STU. This device can be combined with the shunt opening release (-MO1; -MO2) or with the shunt closing release (-MC) to check functionality and continuity.

The control/monitoring Shunt Test Unit allows the continuity of releases with a rated operating voltage between 24 V and 250 V (AC and DC) to be checked, as well as the functionality of the electronic circuit of the release. Checking continuity is carried out cyclically with an interval of 20 seconds between one test and the next. The unit has optical signals by means of LEDs on the front. In particular the following information is indicated: – POWER ON: power supply present – (-MO) TESTING: test being carried out – TEST FAILED: signal following a failed test or in the absence of auxiliary power supply – ALARM: signal after three failed tests. Two relays and a changeover are also available on board the unit, which allow remote signalling of the following two events: – failure of a test (resetting is carried out automatically when the alarm stops) – failure of three tests (resetting is only carried out by means of the manual - RESET – from the front of the unit). There is also a manual - RESET – button on the front of the unit. Characteristics Un

3. Specific product characteristics

Resistance to vibrations

Galvanisation is carried out in accordance with UNI ISO 2081 Standards, classification code Fe/Zn 12, with a thickness of 12x10-6 m, protected by a conversion layer mainly consisting of chromates in compliance with the UNI ISO 4520 Standard. These construction characteristics mean that the whole VD4 series of circuit-breakers and its accessories comply with climate graph 8 of the IEC 60721-2-1 and IEC 60068-2-2 (Test B: Dry Heat / IEC 60068-2-30 (Test Db: Damp Heat, cyclic) Standards.

Altitude The VD4 circuit-breakers are designed to satisfy high levels of resistance to stresses caused by mechanical vibrations. Many versions are able to satisfy both the approval criteria of the major International Shipping Registers (DNV, Lloyd’s Register, RINA) and the qualification criteria of the International Seismic Standards (IEEE 344, IEEE 323 and IEC 60980). For the versions approved by the shipping registers, please contact us.

Tropicalization

VD4 circuit-breakers are manufactured in compliance with the strictest regulations regarding use in hot-humid-saline climates. All the most important metal components are treated against corrosive factors according to UNI EN 12500 Standards environmental class C.

64

The insulating property of air decreases as the altitude increases, therefore this must always be taken into account for external insulation of the apparatus (the internal insulation of the interrupters does not undergo any variations as it is guaranteed by the vacuum). The phenomenon must always be taken into consideration during the design stage of the insulating components of apparatus to be installed over 1000 m above sea level. In this case a correction coefficient must be considered, which can be taken from the graph on the next page, built up on the basis of the indications in the IEC 62271-1 Standards. The following example is a clear interpretation of the indications given above.

Graph for determining the Ka correction factor according to the altitude Example • Installation altitude 2000 m • Operation at the rated voltage of 12 kV • Withstand voltage at power frequency 28 kV rms • Impulse withstand voltage 75 kVp • Ka factor obtained from graph = 1.13.

kA 1,50

m=1

Ka = e m (H – 1000)/8150 1,40

Considering the above parameters, the apparatus will have to withstand (under test and at zero altitude, i.e. at sea level): – withstand voltage at power frequency equal to: 28 x 1.13 = 31.6 kVrms – impulse withstand voltage equal to: 75 x 1.13 = 84.7 kVp.

1,30

From the above, it can be deduced that for installations at an altitude of 2000 m above sea level, with 12 kV service voltage, apparatus must be provided with 17.5 kV rated voltage, characterised by insulation levels at power frequency of 38 kVrms with 95 kVp impulse withstand voltage.

H = altitude in metres; m = value referred to power frequency and the lightning impulse withstand voltages and those between phases.

Anti-pumping device The EL operating mechanism of VD4 circuit-breakers (in all versions) is fitted with a mechanical anti-pumping device which prevents re-closing due to either electrical or mechanical commands. Should both the closing command and any one of the opening commands (local or remote) be active at the same time, there would be a continuous succession of opening and closing commands. The anti-pumping device avoids this situation, ensuring that each closing operation is only followed by an opening operation and that there is no other closing operation after this. To obtain a further closing operation, the closing command must be released and then re-launched. Furthermore, the anti-pumping device only allows circuitbreaker closure if the following conditions are present at the same time: – operating mechanism spring fully charged – opening pushbutton and/or shunt opening release (-MO1/-MO2) not activated – circuit-breaker open.

3. Specific product characteristics

REF 601 protection Device

On request, the REF 601 switchgear protection device is available for protection of the installations, which requires an auxiliary power supply for its operation unlike the previous PR512 which was a self-supplied release. The REF 601 has protections and trip curves in accordance with the IEC 255-3 Standard. It sees to the protection function against overload (51), against instantaneous and delayed short-circuit (50-51) and against instantaneous and delayed homopolar ground fault (50N and 51N). It also detects the second harmonic component to prevent unwarranted tripping on connection of a transformer (68). The unit has 3 inputs from current sensors of the type with Rogowsky coil, one input from external toroidal CT and from the keyboard 4 rated currents can be set: 40, 80, 250 and 1250 A. If the unit is connected to 3 current sensors, the 50N and 51N protection functions are carried out with the vectorial sum of the phase currents; if only 2 current sensors are used, then the external toroidal current transformer must be provided for functions 50N and 51N. The external toroidal current transformer can be with openable core or closed and with any transformation ratio as long with a 1 A secondary current. The ABB current sensors of the type with Rogowsky coil provided for REF 601, are only suitable for installation on MV insulated cables.

66

The characteristics of the device are: - trip precision - wide adjustment ranges - single and simultaneous adjustment of the three phases - no limitation (due to the current sensors) to the rated breaking capacity and at the short-time withstand current of the circuit-breaker - pushbuttons for local electrical operation of the circuitbreaker (opening and closing pushbutton - 5 distinct indicators: “relay in operation”, “relay in trip threshold”, “relay tripped”, “relay tripped due to exceeding phase current”, “relay tripped due to exceeding ground fault current” - interface consisting of an LCD display and of “arrow” keys, “enter” and “esc” for easier navigation inside the “measurement”, “data recording”, “event recording”, “settings”, “configuration” and “test” menus - three user levels: “operator” (only display, with free access, by keeping this key pressed for at least 5 sec.), “configurator” (like the previous one, but also with permission to set the protection parameters, i.e. times and thresholds, and communication, if present - access limited by a password), “administrator” (like the previous ones, but also with permission to set the password and configure the basic settings of the device, such as the rated current access limited by a password) - continual display of the current on the most highly loaded phase and of the round current - recording of the value of the currents which caused the device to trip - storage of the number of openings carried out by the device - event log (storage of the parameters described above in the last 5 trips of the device) in a non-volatile memory - curves “ß = 1” or “ß = 5” and curve “RI” specific for the Belgian market (only REF 601 IEC) - circuit-breaker opening by means of an undervoltage release (only REF 601 CEI) - version, on request, with RS485 4-wire serial communication - MODBUS RTU full duplex protocol - multi-voltage feeder 24 … 240 V a.c.- d.c

Environmental protection programme

Spare parts

VD4 circuit-breakers are manufactured in accordance with the ISO 14000 Standards (Guidelines for environmental management). The production processes are carried out in compliance with the Standards for environmental protection in terms of reduction in energy consumption as well as in raw materials and production of waste materials. All this is thanks to the medium voltage apparatus manufacturing facility environmental management system. Assessment of the environmental impact of the life cycle of the product, obtained by minimising energy consumption and overall raw materials of the product, became a concrete matter during the design stage by means of targeted selection of the materials, processes and packing.
