FS401MK-C6/0.03 residual current circuit breaker with overcurrent protection

The FS401M-K series is a 1P+N pluggable residual current circuit breaker with overcurrent protection for the SMISSLINE TP System for the protection of end user single-phase circuits against overload and short-circuit currents; protection against the effects of sinusoidal alternating and direct pulsating earth fault currents; protection against indirect contacts and additional protection against direct contacts. The APR (K type) type provides an optimal trade-off between safety and continuity of service, thanks to the resistance to unwanted tripping, offering good protection and isolation of resistive and inductive loads
