The ABB S201MR-K16 is a 1-pole miniature circuit breaker rated 16 A with a Trip Curve K characteristic. 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.
10 kA at 277 VAC. That's the maximum fault current it can safely interrupt without damage.
Yes — same 1-pole DIN rail footprint, same terminal layout. Straight swap, no rewiring needed. Just confirm your load current (16 A vs 25 A) and available fault current (10 kA vs 6 kA) are within the S201MR-K16's ratings.
