Center Vee Side Break Switch, Copper (GCH4V)

The GCH4V is a two-insulator, side opening outdoor air disconnect switch constructed primarily of aluminum. Operation is accomplished by the rotation of two insulators in a low profile base design. Unique construction methods through years of field experience, coupled with simple design concepts provide ease of installation as well as long-term dependability.
