G&W model GRAM-64PI vault switches feature load break switching capability with visible break and integral ground position in a totally sealed, submersible, dead front device. The integral ground position eliminates the need to handle any high voltage connections to ground the cable. The switches are designed for use on 3-phase systems with voltages up to 15kV and 630A load break and continuous current. Switches are available with the switch operators on the front side. The high voltage connections are positioned on the bottom of the switch.
The switches are designed to IEEE C37.74 for load break capability.
