| Item Description | DOEPKE residual current circuit-breakers 4-POLE, 16 A, 0.3 A, type a, twin, kurzzeitverzögert, n lef / residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. DFS 4 are two-terminal or two-terminal pair residual current circuit-breakers for single- or three-phase networks. In the standard design, the compact devices are just four module widths wide. They are available with many different residual current types and variants for rated currents up to 125 A. The large two-tier terminals CAN also accommodate large conductor cross-sections. The trip position of the multi-function toggle switch simplifies fault-finding. The free label software helps in the labelling process. The twin design enables a function test of the residual current circuit-breaker without switching off the load circuit. Two complete RCCBS are combined in this design: |
