1. Doepke FI/LS combination
RCBOs combine residual current and circuit breakers in one device (RCCB/MCCB combination). They protect people from fault currents and installations from short circuits and overloads. The DRCBO 4 has a rated breaking capacity of 6 kA. In addition to a tripped indicator, it also features a labeling window. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Switches with characteristic B are the standard protection for lighting and socket circuits. Standard switches are designed for circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz.
Features: pulsating and alternating current sensitivity, mains voltage-independent tripping, compact size for all rated currents, switching position indicator, separate indication of the tripping reason, terminal blocks with a wide clamping cross-section range on both connection sides, neutral conductor on the right, labeling window, mounting type: quick fastening on mounting rail, installation position arbitrary, power supply arbitrary.
Applications: Protection of circuits in residential and commercial buildings as well as industrial plants with TN-S, TT, and TN-C-S networks. In IT networks, RCCB/MCCB switches can be used for disconnection in the event of a second earth fault. Use in systems with TN-C networks and for the protection of circuits where power electronics devices can cause smooth direct fault currents or fault currents with frequencies other than 50/60 Hz is excluded.
