Earth leakage circuit breaker - Residual current breaker with auxiliary DRCCB5 ST025-4/0,03A – Doepke – 09421502 – 4014712223240: Residual current circuit breaker Selftest DRCCB5 ST025-4/0.03A number of poles 4, rated voltage 400V, rated current 25A, rated residual current 0.03A, mounting type DIN rail, residual current type A, short-time delayed type, short-circuit strength (Icw) 10kA, rated breaking capacity 0.63kA, surge current strength 3kA , frequency 50Hz, additional devices integrated other, additional devices factory-mounted monitoring unit, rated switching current additional device 25A, rated voltage additional device 400V, type of control voltage additional device AC, degree of protection (IP) IP20, size (according to DIN 43880) 7, width in modular units 7, installation depth 66.099998mm, residual current circuit breaker (RCCB) switch off the power supply when dangerously high fault currents occur. They protect people, animals and systems. Devices of the DRCCB 5 series are compact two-pole or four-pole residual current circuit breakers with a self-test function. Type A switches are pulse and AC sensitive. This function is independent of the mains voltage. Switches in the Selftest (ST) version automatically carry out a function test of the residual current circuit breaker on a regular basis. This takes place without interruption for the system and without additional wiring effort, since the required power supply is integrated. Properties: monthly self-test, indication of the operating status by LEDs, configurable auxiliary contact, type of installation: quick mounting on DIN rail, any installation position, feed from above, areas of application: the devices are used wherever electrical systems must not be switched off or are difficult to access. This can e.g. B. IT systems or telecommunications systems, agricultural premises. be small wind turbines or sewage treatment plants. The switching status of the RCCB can be transmitted for remote monitoring using an optional Modbus interface module.
