Why Choose the ABB S201MT-K50UC Miniature Circuit Breaker?
The ABB S201MT-K50UC is a high-performance single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. Part of the specialised ABB S200 MT UC series, it provides dependable universal-current protection for demanding AC and DC installations, including industrial, railway and traction applications.
Featuring a Type K tripping characteristic, the S201MT-K50UC is particularly suitable for circuits supplying equipment with relatively high starting or inrush currents. Its 50 A rated current and 10 kA short-circuit breaking capacity provide robust circuit protection while helping reduce unwanted magnetic tripping in appropriate inductive-load applications.
The compact single-pole construction allows the S201MT-K50UC to be integrated efficiently into distribution boards, control panels and transportation electrical systems. Its AC/DC capability, DIN rail mounting and robust S200 MT UC design make it a practical choice where reliable protection and efficient use of panel space are required.
