The ABB S203P-Z10 is a 3-pole miniature circuit breaker (MCB) with a Trip Curve Z characteristic, rated at 10 A continuous current and 277 VAC, with a 10 kA interrupting capacity. It snaps onto a DIN rail, so it integrates into any standard enclosure without drilling.
The S203P-Z10 is rated at 10 A continuous current.
No. The S204-B32 is a 4-pole B-curve 32 A breaker; the S203P-Z10 is 3-pole Z-curve 10 A. They share the same DIN-rail footprint but differ in pole count, trip curve, and ampacity — a direct swap would require rewiring and re-evaluating load protection.
