The K-curve is designed for inductive and motor loads, tripping between 10 and 14 times rated current on short circuits — a tighter band than the Z-curve but wider than the B-curve, giving it selectivity with downstream motor starters while still protecting the cable.","metaTitle":"ABB S203-K6A Miniature Circuit Breaker, 6A K-Curve","metaDescription":"ABB S203-K6A miniature circuit breaker, 6A K-curve, current production.
