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.
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.
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.
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.
