supply earth leakage circuit breaker

     5SM1 residual current operated circuit-breakers with integral overcurrent. Protection combine in fact a protection against earthing faults(differential protection) and a protection against overcurrents detected in the installations magnetothermic protection versions using a rated residual fault current of 30mA also assure an addtional protection in case of direct contacts.5SM1 series are equipped with overcurrent triggers integrated and manufactrued according to the most recent naional and international regulationl:standardsIEC1009-1 and IEC23-18.
