drawing-ar-series-circuit-breaker(2).zip
Small 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.
• Precise, temperature independent operation
• Panel mount
• Integrated auxiliary contacts (optional)
• Small design
• Up to 6 poles configuration

Used in applications where electrical systems, circuits, or components require protection against excessive current. Overloads can occur when motors or other equipment draw more current under heavy operating conditions, potentially causing overheating and component failure. Circuit protection devices are essential where conductor sizes change. Sensitive electronic components, including transformers, require fast-acting protection with rapid overload detection and interruption capabilities to prevent damage and ensure system reliability.
