The K-curve trip characteristic means it tolerates short-duration inrush currents typical of inductive loads like small solenoids, relays, and motor starters — it holds through a moderate surge without nuisance tripping, then clears fast on a hard fault. The 2-pole width occupies two 18 mm module spaces, so it fits a typical 4- or 8-position distribution block. Rated 277 V AC phase-to-neutral on a 480Y/277 V system; common in North American industrial control panels where a supplemental protector guards a single 120 V or 277 V control circuit fed from a panelboard. Listed under UL 1077 as a supplemental protector and CSA 22.2 — the standards that govern overcurrent protection for control-circuit and auxiliary loads, not primary feeder breakers. The UL 1077 listing is the key authority signal for North American panel builders: it tells the inspector the part is accepted for its intended role in a UL 508A industrial control panel.","metaTitle":"S202-K1 1A K-Curve 2-Pole DIN Rail MCB, 277V AC, 6kA","metaDescription":"S202-K1 1A supplemental protector, K-curve, 2-pole, 277V AC, 6kAIC.
