The S201-C32 is a 1-pole miniature circuit breaker rated 32 A with a Trip Curve C characteristic, interrupting 6 kA at 277 VAC. DIN rail mount, UL 1077 listed. Current lifecycle — no obsolescence notice on record.
Curve C means the magnetic trip fires at 5–10× In (160–320 A), so it handles moderate inrush from small motors, transformers, or capacitive loads without nuisance trips. The 6 kA interrupting capacity at 277 VAC is the maximum fault current the breaker can safely clear; verify the available fault current at the panel is below that. 1 pole switches one phase only — use for single-phase branch circuits or as a single-pole protective device in a multi-pole assembly.
Occupies one module width (17.5 mm). Common in UL 508A industrial control panels for branch circuit protection of lighting, small motor loads, or control transformers. Thermal-magnetic trip mechanism — thermal element handles overloads, magnetic coil handles short circuits.
