Why Choose the ABB S201MT-B3 Miniature Circuit Breaker?
The ABB S201MT-B3 is a specialised single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. Part of the ABB S200 MT series, it is engineered for demanding electrical installations, including industrial, railway and rolling-stock applications where dependable circuit protection is required.
Featuring a Type B tripping characteristic, the S201MT-B3 provides sensitive magnetic overcurrent protection for circuits with relatively low normal inrush currents. Its 3 A rated current makes it suitable for low-current control, signalling and auxiliary circuits, while its 10 kA rated short-circuit breaking capacity provides robust protection against electrical faults.
The compact single-pole breaker occupies just one DIN module, helping conserve valuable space within control and distribution assemblies. ABB identifies the S200 MT platform for rolling-stock applications, with the series designed to provide overload and short-circuit protection while meeting the demanding environmental requirements associated with transportation equipment.
