Doepke Residual current circuit breaker DFS 4 040-4/0.03-A R

Residual current circuit breakers (RCCB) switch off the power supply when dangerously high fault currents occur. In this way, they protect people, animals and equipment. The large double-level terminals can also accommodate large conductor cross-sections. The multi-function switch toggle's trip position makes troubleshooting easy. Free labeling
software helps with labeling. Type A switches are pulse and AC current sensitive. This function is independent of mains voltage. Standard version devices are designed for monitoring circuits with a rated voltage of 230 V/400 V and a rated frequency of 50 Hz.
