The 25 A rating means it protects branch circuits up to that continuous current — think lighting, receptacle, or small motor loads in a panel. The C curve (magnetic trip between 5× and 10× rated current) handles moderate inrush from motor starters or transformers without nuisance tripping, unlike a B curve which would trip on the same surge. The 6 kA interrupting capacity at 277 VAC tells you it can safely clear a fault up to that level; if your available fault current is higher, you need a breaker with a higher SCCR or a current-limiting upstream device. ## Where it lands in the panel and what it connects to Snaps onto standard DIN rail inside a distribution board or sub-panel. Single-pole means it switches one phase — common for 120/277 VAC branch circuits where you don't need multi-pole isolation. The thermal-magnetic trip mechanism is self-contained; no external control power needed. Wire it with the line feed on the top terminal and the load on the bottom, per typical panel practice.","metaTitle":"S201-C25 Miniature Circuit Breaker, 25A, 1P, C Curve, 6 kA","metaDescription":"S201-C25 miniature circuit breaker, 25 A, 1-pole, C trip curve, 6 kA interrupting capacity at 277 VAC.
