Doepke RCCB DFS4 004/003A 03A

Residual current circuit breakers (RCCB) disconnect the power supply when dangerously high fault currents occur, thereby protecting 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, these compact devices are four division units wide. They are available with various fault current types and designs with rated currents up to 125 A. The large double-decker terminals can accommodate large conductor cross-sections. The triggered position of the multifunction switch knob facilitates troubleshooting. The free labeling software assists with labeling. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Standard devices are designed for monitoring circuits with a rated voltage of 230 V/400 V and a rated frequency of 50 Hz. Features: - independent triggering from mains and auxiliary voltage.
