Doepke 09945106 DRCBO 4 B25/0.03/3N-A FI/LS combination

RCBOs combine residual current and circuit breakers in one device (FI/LS combination). They protect people from residual currents and systems from short circuits and overloads. DRCBO 4 have a rated switching capacity of 6 kA. In addition to the tripped indicator, they also offer a label window. Type A switches are sensitive to pulse and alternating current. This function is independent of the mains voltage. Switches with tripping characteristic B are the standard protection for light 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. Properties: sensitive to pulse and alternating current, tripping independent of mains voltage, small size for all rated currents, switch position indicator, separate display of the reason for tripping, clamping yoke terminals with a wide clamping cross-section range on both connection sides, neutral conductor on the right, labeling window, mounting type: quick attachment to mounting rail, installation position as desired, feed-in as desired, areas of application: protection of circuits in residential and commercial buildings as well as industrial plants with TN-S, TT and TN-CS networks. In IT networks, FI/LS switches can be provided for shutdown in the event of a second earth fault. Use in systems with TN-C networks and for protecting circuits in which power electronics equipment can cause smooth DC fault currents or fault currents with frequencies other than 50/60 Hz is excluded.
