Why Choose the ABB S802S-K63 Miniature Circuit Breaker?
The ABB S802S-K63 is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding electrical installations. Part of the ABB S800S high-performance MCB series, it combines a Type K tripping characteristic with high current-limiting performance for reliable protection of circuits supplying motors, transformers and other loads with elevated functional current peaks.
With a rated current of 63 A and an ultimate short-circuit breaking capacity of 50 kA at 400/415 V AC, the S802S-K63 provides robust protection where high prospective fault currents must be safely interrupted. Its Type K characteristic makes it particularly suitable for appropriately designed circuits where normal equipment operation can produce significant starting currents.
The S802S-K63 incorporates separate thermal and electromechanical tripping mechanisms for overload and short-circuit protection. Its 2-pole construction, current-limiting operation, DIN-rail mounting and AC/DC capability make it suitable for industrial distribution systems, machinery, automation panels and other professional electrical installations.
