That makes it a good fit for inductive loads like small motors, transformers, and solenoid valves that draw a brief inrush without nuisance-tripping. At 2 A, this breaker handles motor loads up to roughly 0.5 kW on a 230 V line, or smaller control transformers. The thermal element handles the overload protection; the magnetic element clears the short. Single-pole width (roughly 17.5 mm per module) means it takes up one slot in the panel. No special busbar or adapter needed for a standard ABB S200-series distribution board.","metaTitle":"S201P-K2 ABB MCB 1P K 2A 277VAC 10kA DIN Rail","metaDescription":"ABB S201P-K2 miniature circuit breaker, 1-pole, 2 A, Trip Curve K, 277 VAC, 10 kA interrupting rating.

The difference is the interrupting rating: the S201P-K2 offers 10 kA at 277 VAC, while the S201MUC-K2 is rated 6 kA AC and adds a 10 kA DC rating at 250 V. Both snap into the same panel footprint and use the same busbar system, so swapping between them doesn't require rewiring."},{"question":"What is the interrupting rating of S201P-K2?","answer":"The S201P-K2 has a 10 kA interrupting rating at 277 VAC. That's the maximum fault current it can safely clear without damage."},{"question":"Where can I buy S201P-K2 and how do I get a price?","answer":"The S201P-K2 is sourced and quoted to order against an RFQ through independent distribution.
