Doepke Residual current circuit breaker

Residual Current Circuit Breakers (RCCB) disconnect the power supply when dangerously high fault currents occur, thereby protecting people, animals, and installations. The DRCCB 5 series devices are compact two-pole or four-pole residual current circuit breakers with a self-test function. Type A switches are sensitive to both pulsed and alternating currents. This function is independent of the mains voltage. Switches in the Selftest (ST) version automatically perform a function test of the residual current circuit breaker regularly. This is done without interruption to the system and without additional wiring effort, as the required power supply is integrated. Features include: monthly self-test, operational status indication via LEDs, configurable auxiliary contact, mounting type: quick fastening on a mounting rail, installation position flexible, top feeding. Applications: These devices are used wherever electrical installations should not be switched off or are difficult to access. This can include IT systems, telecommunications systems, agricultural facilities, small wind power plants, or wastewater treatment plants. With an optional Modbus interface module, the switching status of the RCCB can be transmitted for remote monitoring.
