The ABB S202-K63 is a 2-pole miniature circuit breaker rated for 63 A continuous current with a Trip Curve K characteristic — meaning it tolerates brief high inrush (typical of motor or transformer loads) while tripping quickly on sustained overloads. The K-curve holds the coil on motor starting but clears a hard short inside the half-cycle window.

Frequently asked questions
Will the S202-K63 drop into a panel specified for the S202M-C63?
Yes — both are 2-pole, 63 A, DIN-rail-mounted breakers from the same S200 family. The S202-K63 uses a K-curve (higher inrush tolerance) versus the C-curve on the S202M-C63. No rewiring needed; the footprint and terminal layout are identical.
