Doepke RCCB DFS4 0404/003EV 03A

Residual current circuit breakers (RCCB) disconnect the power supply when dangerously high fault currents occur, thereby protecting people, animals, and equipment. 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 many different fault current types and designs with rated currents up to 125 A. The large double-decker terminals can accommodate large conductor cross-sections. The tripped 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. Switches in the EV version are intended for use in charging stations for electric vehicles. They have an additional function for detecting smooth DC fault currents up to 6 mA, thus protecting upstream residual current devices.
