hydraulic magnetic circuit breaker

详细描述

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.
The trip point is always at maximum allowable current, independent of ambient temperature. Mid-trip handle to indicate clearly a breaker operation caused by electrical fault. 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.

应用

To be used in any application where electrical systems, circuits or components must be protected against excessive currents that can cause wires or components to overheat. Circuit protection is essential where conductor sizes change or where transformers and electronics need fast overload sensing. The CR-Series 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.
