The S201-C1 is a 1-pole miniature circuit breaker rated at 1 A with a Trip Curve C characteristic, meaning it trips at 5 to 10 times rated current — suited for moderate inrush loads like small contactor coils or control transformers where you need short-circuit protection without nuisance tripping on energisation. Mounts on standard DIN rail, so it slots into any 18 mm-wide position in a distribution board or control panel.
Integration — DIN rail fit and wiring
The 1-pole format occupies a single 18 mm module width, so it fits in the same slot as any other S200-series MCB. Terminal capacity accepts up to 25 mm² conductor; strip length 12–14 mm.
