Low voltage moulded case circuit breakers and low voltage switch disconnectors Low voltage moulded case circuit breakers are used for the switching and protection of power supply cables, motors and other electrical equipment against overloads and short circuit faults. They provide, beside protection function, other functions as remote ON/OFF operation, undervoltage protection, main switch etc. They are available in range from 20 A up to1600 A in 3 and 4 pole versions. Advantages: ■ Small dimensions,modular sizes ■ Possibility of field-instalable accessories - up to 1600A frame size series 2 (EB2) ■...

Low voltage moulded case circuit breakers and low voltage switch disconnectors Microprocessor's MCCBs Microprocessor's MCCBs are available in frame sizes from 250 A up to 1600 A, with rated current from 40 A up to 1600 A. All frame sizes have adjustable thermal and magnetic protection. Series 2: Protection against overload can be adjusted between 0,4 - 1 x In, meanwhile short-circuit protection has already preset different curves, which can be easily selected according to the type of load. Optional Functions: N - Neutral Protection A - Standard relay with LSI Characteristic (where no letters...

Low voltage moulded case circuit breakers with residual current protection Low voltage moulded case circuit breakers with residual current protection Main features and advantages Adjustable residual current tripping thresholds between 30mA and 3A. Adjustable time delay for residual current protection between 60ms and 700ms including INST (instantaneous) and NT (No Trip). Type A: Tripping is ensured for residual sinusoidal AC in the presence of residual pulsating DC. Voltage Presence LED Indicator and Trip Indicator (the yellow button pops up to indicate tripping due to residual current) Adjustable...

Low voltage moulded case circuit breakers with residual current protection Main advantages: ■ Combined protection against overloads, short circuits and earth leakage integrated in one device ■ The new EB2R save the space ■ The EB2R has the same dimensions and fixing as the EB2 MCCBs ■ The EB2R eliminates the need for either an external relay with current transformers or add-on block ■ Residual current is adjustable ■ Earth leakage protection time delay is adjustable ■ Wide range of accessories (as MCCB - only shunt/undervoltage trip units can not be fitted to EB2R) Note: all internal and external...

Note: all internal and external accessories can be used with EB2R - only exceptions are DA shunt trip unit and NA undervoltage trip unit (cannot be fitted to EB2R) etibreak Residual current monitor and pre trip module Residual current monitor and pre trip module (optional) ■ normally open alarm contact (2A, 250V AC) closes on detection of residual current. Alarm treshold is adjustable. ■ Green LED indicates voltage is present ■ Red LED provides visual indications of residual current. ■ Can be configured to provide trip + alarm or alarm only. ■ Remote trip terminals allow tripping by push-button ■...
