RCBO 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 triggered display, they also offer a label window. Type A switches are pulse and alternating current sensitive. This function is independent of the mains voltage. Switches with tripping characteristic C are optimized for circuits with high inrush or peak currents. 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, triggering independent of mains voltage, small size for all rated currents, switching position indicator, separate display of the trigger reason. Clamp clamps with a wide clamping cross-section range on both connection sides, neutral conductor right, label window. Mounting type - quick attachment to mounting rail. Any installation position. Any feed-in. Areas of application - 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, FI-LS switches can be provided for shutdown in the event of a second ground fault. Use in systems with TN-C networks and to protect circuits is excluded. in which power electronics equipment can cause smooth direct residual currents or residual currents with frequencies other than 50-60 Hz.
