Earth Leakage Circuit Breakers

5SM residual current operated circuit breaker with integral over current
protection can be used in the domestic and public field for otimu
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
magnetothermic protection versions suing a rated residual fault current
of 30mA also assure an additional protection in case of direct contacts.
KM 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.
