Reliable Circuit Protection for Railway Electrical Systems
Miniature circuit breakers such as the ABB S204MT-Z32UC protect electrical circuits by interrupting the supply when excessive current caused by an overload or short circuit is detected. The Z characteristic provides a defined sensitive tripping response for circuits and equipment where this protection characteristic is appropriate.
The S200MT UC series is developed for rolling-stock applications and supports universal-current operation, allowing the same product family to be used in both AC and DC circuits. ABB's dedicated S200MTUC traction range incorporates special materials addressing railway fire and smoke requirements, while its construction has been tested for the shock and vibration conditions encountered in rolling-stock applications.
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 electrical systems requiring AC/DC miniature circuit protection.
