Doepke RCCB DFS4 0404/030A 3A

Residual current circuit breakers (RCCB) disconnect the power supply when dangerously high fault currents occur. They protect people, animals, and installations. DFS 4 are two- or four-pole residual current circuit breakers for single-phase or three-phase networks. In standard design, the compact devices are four division units wide. They are available with many different fault current types and designs with rated currents up to 125 A. The large double-decker terminals can also accommodate large conductor cross-sections. The tripped position of the multifunction switch knob facilitates troubleshooting. The free labeling software assists with marking. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Devices in standard design are intended for monitoring circuits with a rated voltage of 230 V/400 V and a rated frequency of 50 Hz. Features: independent tripping from mains and auxiliary voltage.
