That makes this 15 A unit a fit for protecting a small motor branch circuit or an inductive load group — not a general-purpose lighting or resistive load, where Curve C or B would be the normal choice. The AC interrupting rating is 6 kA at 277 VAC; on the DC side it breaks 10 kA at 500 VDC. That DC rating is higher than many comparably sized MCBs — relevant if you are protecting a DC bus or a battery-backed control circuit in the same panel.","metaTitle":"ABB S202MUC-K15 S200MUC MCB, 2P K 15A, 277VAC/500VDC","metaDescription":"ABB S202MUC-K15 miniature circuit breaker, S200MUC series, 2-pole, Trip Curve K, 15 A, 277 VAC / 500 VDC, DIN rail mount.
