That 16 A is the continuous current it carries without tripping. Interrupting rating is 10 kA at 277 VAC — the maximum fault current it can safely clear. Mounts on standard DIN rail (35 mm per EN 60715), so it snaps into any modern panel or subdistribution board. One-pole width saves rail space — 17.5 mm per module — letting you pack more circuits per row.","metaTitle":"ABB S201MR-K16 MCB, 16A 1-Pole K Curve, 10kA 277V","metaDescription":"ABB S201MR-K16 miniature circuit breaker, 16A, 1-pole, Trip Curve K, 277 VAC, 10 kA interrupting rating, DIN rail mount.
