Trip Curve K is the key spec here: it sits between B and C curves, with a magnetic trip threshold of 8–12x rated current. It's not for general lighting or resistive loads — those want a B or C curve. The 2-pole configuration protects both legs of a single-phase 277 VAC circuit or a 480Y/277 VAC line-to-neutral tap. ## Deployment context DIN rail mount means it integrates into a standard control panel enclosure — snaps onto the rail, shares the same busbar system as other modular devices. The 2-pole width takes up two 18 mm module spaces. In a cement plant or similar dusty environment, the sealed thermoplastic housing keeps the grit out of the trip mechanism; no breathing parts to clog. Rated for 277 VAC, so it handles the common control voltage in North American industrial panels without derating.","metaTitle":"ABB S202-K30 Miniature Circuit Breaker, 30A, 2-Pole, Curve K","metaDescription":"ABB S202-K30 30A 2-pole miniature circuit breaker, Trip Curve K, 277 VAC, 6 kA interrupting rating, DIN rail mount.

The S202-K30 is 2-pole, 30 A, Curve K. Different pole count, amp rating, and trip curve; it won't drop in without rewiring and re-coordinating the protection scheme."},{"question":"What compliance documentation does ABB provide for the S202-K30?","answer":"The S202-K30 is UL 1077 listed as a supplementary protector.
