The ABB S202MR-K15 is a 2-pole miniature circuit breaker rated 15 A with a Trip Curve K characteristic, designed for DIN rail mounting in distribution panels and control enclosures. Rated 277 VAC with a 10 kA interrupting capacity, this MCB handles fault currents up to that level without cascading upstream — sufficient for most commercial and light industrial branch circuits. Trip Curve K means the magnetic trip threshold is 8–12× rated current, making it suitable for loads with moderate inrush like motor starters, transformers, and solenoid valves where a Curve C would nuisance-trip.
