GN38-12 Indoor disconnector (isolator) 12KV

The GN38-12 isolation switch is suitable for indoor devices with three-phase AC 50Hz and rated voltage of 12KV. Used for switching on and off high-voltage equipment with voltage and no load.

Product Features

Adopting a busbar through wall type integrated insulation base plate, completely separating the switchgear, busbar compartment, and circuit breaker compartment

Equipped with a different axis manual integrated operating mechanism, it not only ensures the mechanical performance of the isolation switch, but also reduces the operating height for easy operation

Product Detail

Single breakpoint three station structure ensures reliable switch action

Equipped with complete mechanical interlocking devices

Coaxial "refers to the fact that the transmission main shaft and the operating mechanism shaft are the same shaft

'Different shaft' refers to the fact that the transmission main shaft and the operating mechanism shaft are two shafts, with a connecting rod or gear transmission in the middle

The "integrated mechanism" refers to the integrated structure of the isolation switch and operating mechanism, with its external dimensions, installation method, and performance indicators carefully adjusted before the product leaves the factory.
