CAL15(electromagnetic) residual current operated circuit breaker with integral overcurrent protection can be used in the domestic and public field for optimum protection of life against the risks of indirect contacts and electrical installations against short-circuits 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 overcurrent detected in the installations magnetothermic protection versions using a rated residual fault current of 30mA also assure an additional protection in case of direct contacts. CAL15 RCBO has no special operating process, so it can be used by laypeople.

It is in conformity with the standards of IEC 1009-1, EN61009-1 and GB16917-1.
