Residual current operated circuit-breaker with integral overcurrent protection, three-pole+N, 40 A, 0,03 A, B-Characteristic, Type A
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 FIB/FIC residual current operated circuit-breakers with integral overcurrent protection have a rated switching capacity of 6 kA. A tripping indicator and label window facilitate the overview. 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.
mains-voltage-independent tripping, compact design for all rated currents, high short-circuit resistance, switch position indicator, separate indication of fault cause, strain-relief clamps with a wide terminal cross-section range on both connection sides, Neutral conductor right, high electromagnetic compatibility (immunity to interference for industrial applications)
quick fastening to mounting rail, any installation position, supply as desired
Protection of circuits in residential and purpose-built buildings as well as industrial facilities with TN-S 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.
