G&W model GRAM-RP 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 38kV and 630A load break and continuous current. These switches are extremely flexible and are offered in many different styles. Switches are typically sold with the switch operators on the front side. The high voltage connections can be positioned on the bottom, top, or side to ease cable training and installation.
The switches are designed to IEEE C37.71 and C37.74 for load break capability.
