5SM3 2p 30ma rccb and rcbo residual current breaker specifications rating
5SM3 2p 30ma rccb and rcbo residual current breaker specifications rating with integral over current protection can be used in the domestic and public field for protection of life against the risks if in direct contacts and electrical installations against short- circuits or overload. The residual current operated circuit breakers with integral over current. Protection combines in fact a protection against ear thing faults (differential protection) and a protection against over currents detected in the installations magnetic thermal protection versions suing a rated residual fault current of 30mA also assure an additional protection in case of direct contacts.
5SM series are equipped with over current triggers integrated and manufactured according to the most recent national and international regulations: standards IEC1009-1 and IEC2318, their sizes are in compliance with the regulations of the standard DIN43880, one module is 18mm (1pole), front window height equal to 45mm. According to IEC1009-1, FSM type of RCBO has no special operating process, so it can be sued by laypeople.
