That means it tolerates the inrush of transformer-coupled loads, motor starters, and inductive solenoids without nuisance tripping, but still clears a hard short fast enough to coordinate with downstream fuses or contactors. For a 10 A pole, magnetic trip kicks in between 80 A and 140 A — high enough to ignore a motor start, low enough to protect the cable.","metaTitle":"ABB S201M-K10 Miniature Circuit Breaker, K-Characteristic","metaDescription":"ABB S201M-K10 miniature circuit breaker with K-characteristic, 10A, current production.
