| Description de l'article | DOEPKE residual current circuit-breakers 4-POLE, 63 A, 0.5 A, type AC, for point heaters, with AUXIL / 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. Type AC switches only detect AC residual currents. As a result, in germany they are not approved as residual current operated protective devices. Residual current circ |
