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 compact residual current operated circuit-breakers with integral overcurrent protection from the RCBO 1 series are optimised for use in British standard distribution systems. They are distinguished by a high rated switching capacity. The protective guard and a bistable snap-in slider facilitate installation and removal. Type AC switches only detect AC residual currents. As a result, in Germany they are not approved as residual current operated protective devices. Switches with tripping characteristic C are optimised for electric circuits with high inrush or peak currents. Switches in this design are voltage-dependent, hence adapted for the UK market.

mains-voltage-dependent tripping, compact design for all rated currents, high short-circuit resistance, green/red switching position indicator, strain-relief clamps with protection against wires being lodged behind them , bi-stable snap-in slider for easy mounting and removal

quick fastening to mounting rail, any installation position, supply as desired

Power supplies to residential and purpose-built buildings as well as industrial facilities with TN-S, TT and TN-C-S networks. In IT networks, the RCBOs of this series can be set to switch off in the event of a second fault, Not permitted for use in TN-C networks and for protecting systems in which electronic equipment may cause pulsating or smooth DC residual currents or residual currents with frequencies not equal to 50 Hz. Comprehensive protection is not provided with an RCCB type AC. For these applications we recommend our residual current operated circuit-breakers with integral overcurrent protection Type A or our AC-DC sensitive RCBO Type B.
