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. This series has a rated switching capacity of 6 kA. FIB/FIC are available as pulse and alternating current sensitive type A three-pole +N and as universal current sensitive type B single-pole +N or three-pole +N. Type A switches are pulse and alternating current sensitive. 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 230V or 400V and a rated frequency of 50Hz. Properties: - tripping independent of mains voltage, - small size for all rated currents, - high short-circuit strength, - switch position indicator, - separate display of the reason for the fault, - clamping yoke terminals with a wide clamping cross-section range on both connection sides, - neutral conductor on the right, - high electromagnetic compatibility (interference immunity for industrial applications) Mounting type: - quick attachment to mounting rail - installation position as desired Areas of application: - protection of circuits in residential and commercial buildings as well as industrial plants with TN-S and TN-CS networks. In IT networks, FI/LS switches can be provided to switch off in the event of a second earth fault. - Use in systems with TN-C networks and to protect circuits in which power electronics equipment can cause smooth DC fault currents or fault currents with frequencies other than 50/60 Hz is excluded.
