Trip Curve K means the magnetic trip threshold is set to 8–12× In, designed to handle the inrush of inductive loads like small transformers, solenoids, and DC power supplies without nuisance tripping. This makes it a fit for control-circuit protection in panels where standard B or C curves would trip on startup. Interrupting capacity is 6 kA at 277 VAC and 10 kA at 250 VDC — sufficient for most secondary distribution panels and DC bus protection in control cabinets. The DC rating is notably higher than the AC figure, which is typical for breakers optimized for battery or rectifier-fed circuits. Single-pole width (roughly 17.5 mm per pole) keeps panel fill factor tight. Rated for use in ambient temperatures typical of enclosed industrial panels; no forced derating at 40 °C for the 1.6 A rating.","metaTitle":"S201MUC-K16 ABB S200MUC MCB, 1P K 16A AC/DC, 6/10 kA","metaDescription":"ABB S201MUC-K16 miniature circuit breaker, 1-pole, Trip Curve K, 1.6 A, 277 VAC / 250 VDC, 6 kA AC / 10 kA DC interrupting rating.
