GN19-12C-630A indoor high voltage isolating switch for AC 5Hz, rated working voltage 6,10kv; rated working current 200,630,1250A power system. As a circuit with no voltage under the conditions of breaking, closed circuit of the indoor switch equipment used. This isolator is equipped with a CS6-1 type manual actuator.
Two: isolation switch GN19-12C-630A models and meaning
 
Isolation switch GN19-12C-630A need to explain the GN19-12 indoor high voltage isolating switch models, the form is divided into GN19-12 paperback structure; GN19-12C for the wall through (with casing); where: C1 - In the casing side C2 - breaking in the casing side, C3 - both sides are casing. GN19-12Y paperback structure on the installation of live display device type. Common common models are the following:
GN19-12A / GNA GN19-12C / 1000A GN19-12C / 1000A GN19-12C / 1000A GN19-12C /
