Why Choose the ABB S201MT-B25 Miniature Circuit Breaker?
The ABB S201MT-B25 is a high-performance single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding railway and traction applications. As part of the specialised ABB S200 MT traction MCB series, it combines dependable circuit protection with construction developed for rolling stock electrical installations.
This miniature circuit breaker has a 25 A rated current, Type B tripping characteristic and 10 kA short-circuit breaking capacity. The B characteristic is suited to circuits with relatively low inrush currents, providing effective protection for auxiliary, control, distribution and other electrical loads where high starting currents are not normally expected.
The S201MT-B25 is a compact 1-pole DIN-rail MCB with an individual product weight of approximately 0.115 kg. The S200 MT range is specifically engineered for traction applications and is rated to 15 kA Icu according to IEC/EN 60947-2, with R26/HL3 classification according to EN 45545 and Category 1, Class A/B classification according to IEC 61373.

Reliable Circuit Protection for Railway and Traction Systems
Miniature circuit breakers such as the ABB S201MT-B25 protect cables and electrical equipment by automatically interrupting current when an overload or short circuit occurs. Thermal protection responds to sustained overload conditions, while magnetic tripping provides rapid interruption when a sufficiently high short-circuit current is detected.
The S200 MT series is specifically developed for demanding traction installations. Its combination of high short-circuit performance, railway fire-safety classification and resistance to rolling stock shock and vibration conditions makes the S201MT-B25 well suited to electrical distribution and auxiliary circuits aboard railway vehicles.
Typical Applications
- Railway rolling stock electrical systems.
- Train auxiliary electrical circuits.
- Traction electrical distribution panels.
- Rail vehicle control cabinets.
- Power and distribution circuits with relatively low inrush currents.
- Railway equipment requiring compact DIN-rail circuit protection.
