G&W model RPFI padmount switches include load break and 3-phase fault interrupting capability. The fault interrupters provide electronically controlled, resettable over current protection in a totally sealed, dead front device. The RPFI is G&W most compact and economical SF6 insulated switch. The switches are designed for use on 3-phase systems with voltages up to 27kV, 630A load break and continuous current, with 12.5kA symmetrical fault interrupting ratings.
The switches are designed to IEEE C37.72 and C37.74 for load break and C37.60 for 12.5kA symmetrical fault interrupting capability. Padmount enclosures are designed and tested to IEEE C57.12.28 and C57.12.29.
