Center Side Break Switch, Copper (GCH4)

The GCH4 is a two insulator, side opening outdoor air disconnect switch constructed primarily of copper. Operation is accomplished by the rotation of two insulators making the center break switch the easiest operating of all group operated switches. Proven by years of field experience, this switch takes full advantage of unique construction methods to provide both simple operation and long-term dependability.
