Circuit Breakers

Protection of electric applications

Specially designed and certified for use in railway applications

Miniature Circuit Breakers

Compact hydraulic magnetic circuit breaker for railway applications, to protect electronic equipment and components against unintended high currents. Optional with integrated auxiliary contacts to monitor the circuit.

Wabtec circuit breakers can be used in any application where electrical systems, circuits or components need to be protected against excessive currents. This situation can occur when, under load or heavy use, a motor or other load-generating component in the equipment draws additional current from the power source. High currents cause the wires or components to overheat and eventually burn out.
