LuGao proudly leads as a dedicated outdoor vacuum circuit breaker manufacturer, showcasing the Outdoor Vacuum Circuit Breaker (Watchdog Switch)—a versatile solution offering advanced functionalities. When coupled with a reclosing controller, this breaker transforms into an intelligent recloser-type breaker. In its basic mode, the breaker, paired with a reclosing controller and PT reclosing controller, forms a three-segment compound protection system. This system includes control over switch-on rush current, overcurrent protection, and short quick break. Supporting 1-3 reclosing cycles, incorporating low-current ground protection, and featuring wired supervisory control functions, it allows for remote control beneath the pole, with continuous parameter adjustments for the reclosing meter. Beyond its basic mode, the breaker excels with a three-segment compound protection system, providing control over switch-on rush current, overcurrent protection, and short quick break. Users enjoy the flexibility of continuous protection parameter regulation. This breaker stands out in both wired supervisory control and remote control under the pole, offering a comprehensive solution for diverse power distribution scenarios. Choose LuGao for cutting-edge innovations that redefine the benchmarks of outdoor vacuum circuit breakers.
