Trip Curve K means the magnetic trip threshold sits between 8 and 12 times the rated current. That is higher than a B-curve (3–5×) or C-curve (5–10×), so it tolerates the inrush from motor loads, transformers, or lighting ballasts without nuisance tripping — but still trips fast on a hard short. For a 32 A breaker, that magnetic pickup is roughly 256–384 A. ## Where it fits in a panel Two-pole width (2 modules at 17.5 mm each) means it occupies 35 mm of rail space — standard for a 2P MCB in this class. No extra clearance needed beyond the usual finger-safe terminal shrouds.","metaTitle":"ABB S202MUC-K32 MCB, 2P K 32A, DIN Rail","metaDescription":"ABB S202MUC-K32 S200MUC series MCB, 2-pole, Trip Curve K, 32 A, 277 VAC / 500 VDC, 6 kA AC / 10 kA DC interrupting capacity.
