Why Choose the ABB S802S-UCK63 Miniature Circuit Breaker?
The ABB S802S-UCK63 is a high-performance 2-pole miniature circuit breaker (MCB) engineered for demanding DC circuit protection. Part of ABB's S800S-UC range, it protects cables and conductors against overloads and short circuits while providing the high fault-interruption performance required in industrial DC systems.
With a rated current of 63 A, a UC-K / Type K tripping characteristic and an ultimate short-circuit breaking capacity of 50 kA at 500 V DC, the S802S-UCK63 is suited to circuits where functional current peaks may occur during normal operation. Its 2-pole architecture enables operation at up to 500 V DC while maintaining ABB's specified high breaking capacity.
The S802S-UCK63 combines thermal overload protection with electromechanical short-circuit protection and rapid arc extinction. Its compact modular construction, screw terminals and compatibility with S800 accessories make it a robust choice for industrial DC distribution, machinery, automation systems and other professional applications requiring dependable high-performance protection.
