Indoor high voltage load break switch FZN25 details listed as belows:
Application
It is used in the ring network city distribution and industrial equipment of 12KV and three-phase AC 50Hz to cortrol load and short-circuit. Because the switch with fuse protecting transformer etc more reliably than circuit breaker. It is especialy suitable for ring network clouble radial distribution and package substation.
