3VT Moulded Case Circuit Breakers compact, modular and safe up to 1,600 A3VT moulded-case circuit breakers are an intelligent and cost-effective way to achieve high performance andavailability. These 3VT circuit breakers feature a compact design to save space, thanks to the modularity of thecircuit breakers ranging from 10 A to 1,600 A. You can choose either thermal-magnetic or microprocessor basedtrip units. In addition, the entire range has only three families of internal accessories. The result: maximumbenefit, minimum expense.Front operated RotaryHandleMotorized operatingMechanismTechnical features Rated current range from 16 A to 1,600 ANo De-rating up to 50 CMicroprocessor based overcurrent tripunits from 3VT2 onwards3- and 4-pole versionsFixed-mounted, plug-in and draw-outversionsWide range of standard externalaccessoriesConforms to the following standards:IEC 60947-1, IEC 60947-2, IEC 60947-3IS 13947-1, IS 13947-2, IS 13947-3Line-load reversibleSpecial purpose trip unit for motor &generator protectionUndervoltage & shunt trip coil withmultiple voltage settingsMCCBMain Switching UnitMicroprocessor basedTrip UnitsModular and site fittable trip unit:3VT2 to 3VT5 Wide range of microprocessor based trip unitsselectable as per applicationTrip units can be easily changed at siteAdjustment range from 40% to 100% InA switch disconnector block can be used in placeof trip units as a switch disconnector in MCCBdesign, and to have access to the complete rangeof MCCB accessoriesWide range of operating mechanisms: Rotary handles (front- or side-operated)Motor mechanism with or without cycle counter3

The circuit breakers are with In values in astandardized current range from 40A to 160A Short-circuitreleases are fixed at 4 x In.Characteristic „L“,In 40, 50, 63, 80, 100, 125, 160 A43VT1 circuit breakers with characteristic “D“ have the option ofsetting to a reduced current in a range of approximately 0.75 . 1In. The circuit breakers are with In values in a standardized currentrange from 16A to 160A. The short-circuit release is adjustable.Characteristic „D“, In 16, 20, 25 ACharacteristic „D“,In 32, 40, 50, 63, 80, 100, 125, 160 A
3VT2.5 Microprocessor based Trip UnitsOvercurrent releases ETU LP - LinesProtecting linesThe 3VT9.-6AB00 release is to be used with 3VT2.5 mainswitching units.The release has a thermal memory. The rated currents of thereleases are given by their type designations and correspond to astandardized series of currents. The short-circuit release is set at 4 In. It is simple, because it does not require any adjustment.Therefore, it is intended for less complicated applications.Overcurrent releases ETU DP - DistributionProtecting lines and transformersThe 3VT9.-6AC00 release is to be used with 3VT2.5 mainswitching units.Operation of the release is controlled by a microprocessor. Therelease is equipped with a thermal memory that can be disabled.After disabling the thermal memory, the thermal release remainsactive. The operational state 70% of Ir is signalled by an LEDindicator that flashes green in a 1.5s interval. As the load grows,the blinking frequency increases. In case of a load larger than110% of Ir, this LED will turn red and will begin to blink red justbefore tripping. The releases have tripping characteristicsespecially designed for practical purposes that provide for optimalexploitation of transformers up to 1.5 Ir. The releases offer simpleadjustment of the tripping characteristics.Overcurrent releases ETU MP - Motors Direct protection for motors and generators Possibility for protecting lines and transformersThe 3VT9.-6AP00 release is intended only for 3VT2.5 switchingunits.The operation of the release is controlled by a microprocessor. Therelease is equipped with a thermal memory that can be disabled.After disabling of the thermal memory, the thermal releaseremains active. When one or two phases fail (due to currentgreater than Ir in the remaining phases), in the M-characteristicmode, the switch will open with a 4 s delay. Another parameterfor adjusting the release consists of the rated current and shortcircuit tripping level. The time delay of the short-circuit releasecan be set to 0 or 50 ms. The operational state 70% of Ir issignalled by an LED indicator that flashes green in a 1.5 s interval.As the load grows, the blinking frequency increases. In case of aload larger than 110% of Ir, this LED will turn red and will begin toblink red just before tripping. The releases have trippingcharacteristics especially designed for practical purposes thatprovide for optimal exploitation of transformers up to 1.5 Ir. Atotal of 8 characteristics can be set on the release. Mode “M”provides 4 characteristics suitable for protecting motors and inmode “TV” are 4 characteristics for protecting transformers andlines. The shape of each characteristic can be changed using aselector switch.RCD Module for 3VT1 (upto 160 A) MCCBThe RCD module is used along with the MCCB to provideprotection to personnel & equipments from Earth leakage currentdue to insulation failures or due to direct contact.Available in two version Fixed setting of 30mA Adjustable setting from 30mA to 3A with a time delay settingof 0-1secFor more details please contact our sales officeNewAdjustable version is further equippedwith: Test push-button Led indication for Alarm and trip Dielectric testing switch for electroniccircuits (for dielectric test) to isolate theRCD electronic circuit during dielectrictest (also available in fixed version)5
