It mounts on a standard DIN rail, making it a direct fit for existing panel layouts in control cabinets and distribution boards. The 1 A rating means this breaker protects a circuit drawing up to 1 A continuously. Curve C provides a magnetic trip threshold of 5 to 10 times the rated current, so it handles moderate inrush from small transformers or control power supplies without nuisance tripping, while still clearing a hard fault quickly. ## AC and DC ratings Rated 277 V AC and 500 V DC, the S202MUC-C1 covers both single-phase AC branch circuits and DC control loops. The interrupting capacity is 6 kA on AC and 10 kA on DC, which is the fault current it can safely clear without welding contacts or rupturing the case. For a 1 A breaker, 6 kA gives substantial headroom over the typical 5 kA available fault current in most panelboards.","metaTitle":"ABB S202MUC-C1 MCB 2P C 1A AC/DC, 6kA/10kA","metaDescription":"ABB S202MUC-C1 miniature circuit breaker, 2-pole, Curve C, 1 A, 277 V AC / 500 V DC.
