When an overloaded circuit or short-circuit current occurs, the current sensor transmits collected current signals to the intelligent controller. The controller issues a trip command to energize the tripping coil, releasing the energy-stored spring in the operating mechanism. This causes the contacts to rapidly separate, effectively extinguishing the arc.

Vacuum Circuit Breaker

The product features a precision-engineered operating mechanism that controls opening and closing operations. It includes high-efficiency terminals for stable connections and a vacuum interrupter as the core arc-extinguishing component. The contact arm is designed for drawout type breakers, while silver-plated copper contacts enhance conductivity and oxidation resistance.

Circuit Breaker Components

The drawout chassis provides reliable support for movable parts, and the insulating cylinder safely encapsulates the vacuum interrupter. Aviation connectors offer quick-disconnect functionality, and finger cluster contacts ensure stable electrical connections.

Breaker Internal Structure

This industrial-grade circuit breaker is designed for reliable performance in demanding electrical systems. The vacuum arc-extinguishing technology provides superior protection against electrical faults.
