Trip Curve K is the key spec here. It's designed for inductive loads — motors, transformers, solenoids — where the inrush current can be 8–12× the full-load rating. The magnetic trip threshold sits higher than a C-curve (typically 8–14× In) so it won't nuisance-trip on a motor start, yet still clears a hard fault fast. At 20 A, this breaker handles a 3–4 kW motor on 277 V single-phase, or a group of smaller inductive loads in a panel.","metaTitle":"S201P-K20 MCB 1P K 20A 277VAC, 10 kA","metaDescription":"ABB S201P-K20 miniature circuit breaker, 1 pole, Trip Curve K, 20 A, 277 VAC, 10 kA interrupting rating.
