5SM1 residual current operated circuit breaker with integral overcurrent protection can be used in the domestic and pubilc field for automatic protection of life against the risks if indirect contacts and electrical installations against short circuit or overload. The residual current operated circuit breakers with integral overcurrent. Protection combine in fact a protection against earthing faults (differential protection) and a protection against overcurrents ***ected in the installations magnetothe- rmic protection versions using a rated residual fault current of 30mA also assure an additional protection in case of direct contacts. 5SM1 series are equipped with overcurrent triggers integrated and manufactured according to the most recent naional and international regulations: standards IEC1009-1 and IEC23- 18, their sizes are in compliance with the regulations of the standard DIN43880, one module is 18mm (1 pole), front window height equal to 45mm. According to IEC1009-1, SM type of RCBO has no special operating process, so it can be used by laypeople.
