Rated 277 V AC with a 6 kA interrupting capacity, and 500 V DC with 10 kA interrupting capacity. The 2-pole footprint fits two module-widths in a distribution board or enclosure, leaving room for auxiliary contacts or surge arrestors on adjacent slots.
Deployment context
Designed for DIN-rail mounting in industrial control panels, distribution boards, and sub-distribution enclosures. The S200MUC series is ABB's compact MCB line for commercial and light industrial applications where space is at a premium. Trip Curve C pairs well with mixed loads — lighting banks, small motors, contactor coils — where the inrush is above resistive but below the heavy-start curve of D. For purely resistive or low-inrush circuits, Curve B would trip faster; for high-inrush transformers or welders, Curve D is the better call.
