FS400 RCBO

9PAA00000231505_3200x2143-1

Pluggable solutions for complete protection 

FS400 RCBOs offer 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, as well as protection against indirect contact and additional protection against direct contact. 

Using the SMISSLINE TP system‘s unique SMISS CLICK function, RCBOs can easily be plugged into one pluggable socket system with integrated busbars.

FS401 and FS403 E and M range

Function: 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.

RCBO-image-1

FS401MK, FS402MK and 403MK

Function: protection against the effects of sinusoidal alternating and direct pulsating earth fault currents, providing an optimal trade-off between safety and continuity of service thanks to the resistance to unwanted tripping; protection against indirect contact and additional protection against direct contact (IΔn=30 mA); protection and isolation of resistive and inductive loads.

For FS402 both poles are thermal and magnetic protected for use for IT network.
