G&W Electric model PVI padmount switches include load break and fault interrupting capability. The fault interrupters provide electronically controlled, resettable over current protection in a totally sealed, dead front device. The PVI can be configured to provide 1-phase or 3-phase operation of the fault interrupting ways. The switches are designed for use on 3-phase systems with voltages up to 38kV, 630A load break, and continuous current, with 12.5kA and 20kA symmetrical fault interrupting ratings. The PVI is one of G&W Electric’s most versatile switch styles because it can be ordered with front accessible switch operators and bushings (front access) as well front and back access switch to replace existing pad mount air gear installations.
The switches are designed to IEEE C37.72, C37.74, and C37.60 for load break and fault interrupting capability. Padmount enclosures are designed and tested to IEEE C57.12.28 and C57.12.29.
