Short Description

Circuit breaker

Long Description

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

The trip point is always at maximum allowable current, independent of ambient temperature. With unique arc chute design which results in high interrupting capacities. Up to 6 poles which all break its electronic circuits when 1 breaker trips, for optimal protection of the system. Wide range of currents and options available.

Application

To be used in high current or high voltage applications where electrical systems, circuits or components must be protected against excessive currents that can cause overheating. Circuit protection is essential where conductor sizes change or where transformers and electronics need fast overload sensing. The ER circuit breaker can be used in all railway applications requiring overload and short-circuit protection, e.g. HVAC, door control, braking and passenger information systems.
