G&W Electric model LPFI 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 switches are designed for use on 3-phase systems with voltages up to 27kV, 630A load break and continuous current, and 12.5kA symmetrical fault interrupting ratings. They feature compact footprints due to their front access construction.
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.
