1. Main applications:
GN19-12(C) indoor high-voltage isolating switch is used in the AC 50Hz power system with rated voltage of 12kV and with rated current of less than  1250A for closing and opening circuit under the voltage without load. The isolating switch can be equipped with a CS6-1 manual operating mechanism and an optional live display device.

2.Technical Parameters:
 

Model	Rated voltage (kV)	Rated current (A)	Rated peak withstand current (kV)	Rated short- time withstand  current (kA/4S)	Power frequency withstand voltage for 1 minute (kV)	Lightning impact voltage (kV)
