Product Description

Fzn25 Indoor LBS Vacuum Load Circuit Breaker-Fuse Combination

Product Information 
It is used in the ring network city distribution and industrial equipment of 12KV and three-phase AC 50Hz to control load and short-circuit. Because of the switch with fuse protecting transformer etc more reliably than circuit breaker. It is especially suitable for ring network cloud radial distribution and package substation.
