The K-curve holds the coil on motor starting but clears a hard short inside the half-cycle window.","metaTitle":"ABB S202-K63 MCB, 2P, 63 A, Curve K, 277 V AC, DIN Rail","metaDescription":"ABB S202-K63 miniature circuit breaker, 2-pole, 63 A, Trip Curve K, 277 V AC, 6 kA interrupting rating, DIN rail mount.

The S202-K63 uses a K-curve (higher inrush tolerance) versus the C-curve on the S202M-C63.
