Reliable Circuit Protection for Railway Electrical Systems
Miniature circuit breakers such as the ABB S204MT-K30 protect electrical circuits by interrupting the supply when excessive current caused by an overload or short circuit is detected. The K tripping characteristic is suited to applications where the protected circuit can experience higher starting or inrush currents while still requiring defined overload and short-circuit protection.
The S200MT series is designed for traction and railway applications, making the S204MT-K30 suitable for integration into railway electrical distribution, auxiliary power, control and signalling 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.
