GN19-12C-630AGN19-12 (GN19-12C) indoor high-voltage isolation switch is suitable for AC 5Hz, rated working voltage of 6.10kv; In power systems with rated operating currents of 200, 630, and 1250A. As an indoor switchgear used for breaking and closing circuits under voltage and no load conditions. This isolation switch is equipped with a CS6-1 manual operating mechanism.


2： Model and meaning of isolation switch GN19-12C-630A



The isolation switch GN19-12C-630A needs to be explained that the GN19-12 indoor high-voltage isolation switch model is divided into GN19-12 flat structure type; GN19-12C is a through wall type (with conduit); Among them: C1- rotation on the casing side C2- disconnection on the casing side, C3- both sides are casing. The GN19-12Y flat structure is equipped with a charged display device. The common models are as follows:


GN19-12A400A GN19-12/630A GN19-12/1000A GN19-12/1250A GN19-12C/400A GN19-12C/630A GN19-12C/1000A GN19-12C/1250A
