FS403MK-C25/0.3 Residual Current Circuit Breaker with Overcurrent Protection

The FS403M-K series is a 3P+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
