Reliable Circuit Protection for Railway and Traction Systems
Miniature circuit breakers such as the ABB S202MT-B13 automatically disconnect an electrical circuit when excessive current occurs because of an overload or short circuit. This helps protect cables, conductors and connected electrical equipment while allowing the circuit breaker to be reset after the electrical fault has been identified and corrected.
The ABB S200MT range is specifically developed for railway applications and combines dependable circuit protection with construction suited to demanding transportation environments. The B characteristic provides comparatively sensitive magnetic operation, making the S202MT-B13 particularly suitable for control, auxiliary and other circuits where substantial normal inrush currents are not expected.
Typical Applications
- Railway and rolling stock electrical systems.
- Traction electrical installations.
- Control and auxiliary circuits.
- Resistive and lower-inrush electrical loads.
- Industrial control panels and switchgear.
- Transportation and automation electrical systems.
