Hydraulic magnetic circuit breaker for very high current 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 3 poles which all break its electronic circuits when 1 breaker trips, for optimal protection of the system. Wide range of currents from 100 A to 700 A and many options available.
Application
To be used in every high current application where electrical systems, circuits or components must be protected against too high currents. This situation can occur, when under strained or heavy use a motor or other load-generating component within the equipment will draw additional current from the power source. High currents cause the wires or components to overheat and ultimately burn up.
A circuit protection device should be employed at any point where a conductor size changes. Many electronic circuits and components like transformers have a lower overload withstand threshold level than conductors such as wires and cables. These components require circuit protection devices featuring very fast overload sensing and opening capabilities.
The FR circuit breaker can be used in all Railway applications where protection against overload and short circuit is necessary, for example HVAC systems, (door) control systems, braking systems, passenger information systems, etc.
