The ABB S203-D32 is a 3-pole miniature circuit breaker rated 32 A with a Trip Curve D characteristic, mounted on DIN rail. The 10 kA interrupting rating at 480Y/277 VAC tells you it can safely clear a fault up to that level without welding contacts or cascading upstream.
The S203-D32 is rated for 10 kA interrupting capacity at 480Y/277 VAC, which covers most commercial and light industrial fault levels.
The S203-D32 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or price figures are listed here.
Both mount on DIN rail and share the same 3-pole form factor, but the S203M-C50 is a 50 A C-curve breaker. The S203-D32 is 32 A with a D curve — the higher inrush tolerance is the main difference, but the physical footprint is compatible.
