The S201P-K10 is a 1-pole miniature circuit breaker rated 10 A with Trip Curve K, designed for DIN-rail mounting in distribution panels. The 10 A continuous rating sets the maximum resistive load it carries without tripping; the K-curve means it holds through moderate inrush (8–12× rated current) typical of motor starters and transformer primaries, then trips fast on hard shorts. The 10 kA interrupting rating at 277 V AC tells you it can safely clear a fault up to that level without welding contacts or cascading upstream — sized for most commercial and light industrial panelboards where the available fault current stays under 10 kA.

Frequently asked questions
Where can I buy S201P-K10?
We source and supply the S201P-K10 to order against an RFQ. Availability and current pricing are confirmed at quote time.
What are the key ratings of S201P-K10?
Rated 10 A, Trip Curve K, 1-pole, 277 V AC, with a 10 kA interrupting rating. Mounts on DIN rail.
What does Trip Curve K mean on this breaker?
Trip Curve K provides magnetic trip between 8 and 12 times the rated current, so it handles the inrush of motor and transformer loads without nuisance tripping while still clearing short circuits fast.
