HKL-3S-12 Hot Selling Outdoor Type Vacuum Circuit Breaker

Overview
HKL-3S-12 series outdoor high-voltage three-phase permanent magnet vacuum circuit breakers are a new generation of intelligent vacuum circuit breakers on poles mounting developed by our company, which integrates domestic and foreign advanced technology, learns from others, adopts new design concepts and the latest technology. This product can be used as a pole mounting switch in the distribution network, and can be easily realized, protected, measured and communicated with various control units produced by our company. It is the first-choice equipment to realize the automation and miniaturization of the distribution network.
