Why Choose the ABB S204MT-B6 Miniature Circuit Breaker?
The ABB S204MT-B6 is a compact and reliable miniature circuit breaker (MCB) designed to provide overload and short-circuit protection for electrical circuits in traction, railway and rolling-stock applications. As part of the ABB System pro M compact S200MT series, this four-pole breaker provides dependable circuit protection for AC electrical systems in demanding railway environments.
The S204MT-B6 combines a B tripping characteristic with a 10 kA rated breaking capacity, providing a defined protection response for suitable circuits where rapid protection against overload and short-circuit conditions is required. Its 6 A rated current makes it suitable for appropriately sized auxiliary, control and distribution circuits.
Designed for AC supply and DIN-rail mounting, the S204MT-B6 is suitable for integration into electrical distribution boards, control cabinets and railway equipment. Its four-pole configuration provides protection across a multi-pole circuit while maintaining the compact installation format associated with the System pro M compact range.

Reliable Circuit Protection for Railway Electrical Systems
Miniature circuit breakers such as the ABB S204MT-B6 protect electrical circuits by interrupting the supply when excessive current caused by an overload or short circuit is detected. The B tripping characteristic provides a relatively sensitive tripping response for suitable electrical circuits and applications where the connected loads have limited inrush current.
The S200MT series is designed specifically for traction and railway applications, making the S204MT-B6 suitable for integration into railway electrical distribution, auxiliary power and control systems where compact circuit protection is required. Its four-pole design allows multiple circuit conductors to be protected and isolated within a single compact device.
Typical Applications
- Railway rolling-stock electrical systems.
- Traction auxiliary circuits.
- Railway control and signalling equipment.
- On-board electrical distribution systems.
- Auxiliary and control circuits in rail vehicles.
- Industrial AC electrical systems requiring compact miniature circuit protection.
