Residual current circuit breaker with overcurrent protection 40A 30mA Din Rail RCBO Magnetic type 1P + N , 3P+N AC
STRO7-40 residual current circuit breaker is in conformity with the standards of IEC61008.It can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunkline.Thus it is suitable to avoid the shock hazard and fire caused by earth leakage.It can be used in circuits up to single phase 240V,three phase 440V,50 or 60Hz.
Description
Residual Current Circuit Breaker with Over Current Protection is used to protect against electrical leakage in the circuit of 50/60Hz, rated voltage 230/400V,rated current up to 40A.
When electirc shock happens or the residual current more than the fixed value, the RCCB can cut off the power within 0.1s automatically protecting the personal safety and preventing the equipement from the fault resulted from the residual current.
So the RCCB can protect the circuit against overload, short circuit and electrical leakage
