RPFI – Load Break Switching & Fault Interrupting

RPFI - Load Break Switching & Fault Interrupting

G&W Electric 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 Electric’s 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.

Features and Benefits

  • Construction – Available compact construction with front accessible switch operators and bushings. Vault construction is also available with top or bottom bushings or top access to operators and bushings.
  • Visible Break – Load break ways are equipped with visible break to view the open and closed positions.
  • Fault Interrupting – Three phase fault interrupting up to 12.5kA with selectable industry curves including fuse emulation curves.
  • Automation – Available for motor automation with portable or permanently mounted motor and controls. A variety of relays such as SEL, ABB, and GE are available with G&W Electric programming and cabinet construction. Cabinets can be ordered in a low voltage enclosure for padmount, pedestal or IP68 rated submersible for vault installed switchgear. Programming for automatic source transfer, or LaZer custom solutions are available.
