Magnetic trip threshold is 8–12× rated current (80–120 A for this 10 A breaker), so it holds through the magnetizing inrush of a small transformer or the locked-rotor surge of a motor starter without opening. That makes it a common choice for panel builders feeding inductive branch circuits where a C curve (5–10×) might nuisance-trip and a D curve (10–20×) might not protect the downstream wiring tightly enough. ## Panel Integration Snap-on DIN rail mount, standard 2-pole width (36 mm). Rated for 277 V AC phase-to-neutral or line-to-line on a 2-pole single-phase or three-phase wye system. Verify the SCCR at the panel level — this breaker's rating is the maximum it can clear, not the panel's rating.","metaTitle":"ABB S202PR-K10 MCB 2P K-Curve 10A 277VAC DIN Rail","metaDescription":"ABB S202PR-K10 miniature circuit breaker, 2-pole, 10A, trip curve K, 277VAC, 10kA interrupting rating.
