Why Choose the ABB S201MT-B13NA Miniature Circuit Breaker?
The ABB S201MT-B13NA is a specialised 1P+N miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding railway and traction electrical systems. Part of the ABB S200 MT traction MCB series, it combines a protected phase pole with neutral switching in a compact modular device for rolling stock distribution, auxiliary and control circuits.
This miniature circuit breaker features a 13 A rated current, Type B tripping characteristic and 10 kA short-circuit breaking capacity. The B characteristic is suited to circuits with relatively low starting and inrush currents, making the S201MT-B13NA suitable for compatible auxiliary, control, signalling, monitoring and distribution loads.
The 1P+N configuration enables coordinated switching of the phase and neutral conductors while providing overcurrent protection on the phase pole. Combined with the traction-focused S200 MT platform and DIN-rail mounting, the S201MT-B13NA provides a practical circuit-protection solution for railway electrical distribution and control assemblies.

Phase and Neutral Switching for Traction Circuits
The 1P+N configuration combines an overcurrent-protected phase pole with a switched neutral pole, allowing both conductors to be disconnected together. This arrangement is useful in railway auxiliary and control circuits where coordinated phase and neutral isolation is required while overcurrent protection is applied to the live conductor.
The Type B characteristic is suited to circuits with relatively low temporary inrush currents. During sustained overload conditions, the thermal tripping mechanism disconnects the protected circuit, while magnetic operation provides rapid response to severe short-circuit faults. Together with the specialised S200 MT traction platform, these characteristics make the S201MT-B13NA suitable for dependable protection of compatible railway electrical circuits.
