Reliable Circuit Protection for DC and Traction Systems
Miniature circuit breakers such as the ABB S202MT-Z50UC 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 breaker to be reset after the electrical fault has been identified and corrected.
The ABB S200MTUC range is developed for demanding traction and industrial electrical environments and provides protection for both AC and DC circuits. The Z characteristic offers sensitive magnetic operation, making the S202MT-Z50UC particularly suitable for circuits where rapid disconnection at comparatively low short-circuit currents is required.
Typical Applications
- Railway and rolling stock electrical systems.
- DC distribution and protection circuits.
- Traction electrical installations.
- Sensitive electrical and electronic circuits.
- Industrial control panels and switchgear.
- Automation and transportation electrical systems.
