Description of rcbo breaker
The rcbo breaker designed for AC circuits of 50Hz and rated voltage 240V, the RB12LE-40 series RCBO caters to current demands up to 40A. It safeguards human lives and electrical equipment by swiftly cutting off power in case of electric shock or when grid leakage or voltage exceeds certain values. Furthermore, it provides protection against overload and short circuits. In addition, it can effectively handle non-frequent switching of electrical appliances and lighting circuits under normal working conditions.
Designed for the lighting and distribution systems of industries and commercial setups, it strictly complies with the IEC/EN 61009-1 standard
