Description of rc bo breaker
The RB10L-40 series RCBO is designed for AC 50Hz circuits with a rated voltage of 240V and a current rating of up to 40A. If a human experiences an electric shock or if the grid’s current or voltage surpasses the set values, the rc bo actively disconnects the faulty power quickly. This action ensures the safety of both humans and electrical equipment. Moreover, the rc bo can protect against overload and short circuits. Furthermore, it can toggle the electrical facilities and lighting circuits on and off as long as the circuit operates properly.
Designed for the lighting and distribution systems of industries and commercial setups, it strictly complies with the IEC/EN 61009-1 standard
