Earth leakage circuit breaker Doepke
RCBOs combine residual current and miniature circuit-breakers in a single device (RCBO). They protect people against residual currents and systems against short-circuit and overload. The DRCBO 4 have a rated switching capacity of 6 kA. They provide a labelling area in addition to the tripping indicator. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Switches with tripping characteristic B are the standard protection for lighting and socket circuits. Standard switches are designed for electric circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz. Properties: pulsating current-sensitive and AC current-sensitive; mains-voltage-independent tripping; compact design for all rated currents; switch position indicator; separate indication of tripping cause; strain-relief clamps with a wide terminal cross-section range on both connection sides; neutral conductor right; labelling area; Mounting: quick fastening to mounting rail; any installation position; supply as desired; Application areas: Protection of circuits in residential and purpose-built buildings as well as industrial facilities with TN-S, TT and TN-C-S networks. In IT networks. the RCCB/MCBs can be set to switch off in the event of a second earth fault; Not permitted for use in systems with TN-C networks; not permitted for protecting circuits in which the power electronics equipment may cause smooth DC residual currents or residual currents with frequencies not equal to 50/60 Hz.
