The DIN-rail mount fits standard panel enclosures. ## Trip Curve K and application fit Trip Curve K provides a magnetic trip threshold of 8 to 12 times the rated current, which means it tolerates the inrush of inductive loads like motors and transformers without nuisance tripping, while still protecting against short circuits. For a 16 A breaker, that magnetic pickup starts around 128 A. This makes it a fit for motor branch circuits and transformer primary protection where a standard Curve C might trip on startup. ## DC rating and interrupting capacity Rated for 500 VDC with a 10 kA interrupting capacity, this breaker handles DC bus circuits in drives or solar combiner boxes. The 6 kA AC rating at 277 VAC covers single-phase line-to-neutral applications. The DC interrupting rating is higher than the AC rating, which is typical for breakers designed to break DC arcs. The S202MUC-K16 carries a current lifecycle status.","metaTitle":"ABB S202MUC-K16 MCB, 2P K 16A, 277VAC/500VDC","metaDescription":"ABB S202MUC-K16 miniature circuit breaker, 2-pole, Trip Curve K, 16 A, 277 VAC / 500 VDC, 6 kA AC interrupting capacity.
