Product details

It's sized for a 0.75 kW motor at 400 V AC, and its 100 kA breaking capacity at 400 V AC means it can handle high-fault-current panels without cascading upstream — critical for SCCR compliance on a machine feeder.

Spring-loaded terminals for both main and auxiliary circuits — accepts 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule. No backwards or side clearance needed (0 mm gap), so it rows tight on the rail. Auxiliary switch extension possible if you need remote status feedback.
