■FAULT CLEAR^®

FAULT CLEAR^® consists of three independent solid dielectric insulators
(Embedded vacuum interrupter(VI)) that enable operation by phase.
The equipment is for MV overhead distribution line.

❚ Working directly with SEL controller

FAULT CLEAR^® works directly with “SEL-651R" and 32-pin control cable for three-phase/triple-single application and "SEL-351RS^® "controller with 10-pin control cable for single-phase application.

＊ SEL-351RS^® is a registered trademark of the Schweitzer Engineering Laboratories, Inc.(SEL)

FAULT CLEAR^® can be operated by either three modes depending on controller settings:

  1) Single-phase trip / single-phase lockout

- Each phase shall trip and lockout independently.

  2) Single-phase trip / three-phase lockout

- If one phase trip, the other two phases shall also trip to lockout to prevent single-phasing.

  3) Three-phase trip / three-phase lockout

- All phases trip and close simultaneously.

❚ Pole-ready design

FAULT CLEAR^® is “pole-ready” design for easy installation at the site, which is included lightning arresters, NEMA pads, PTs for the controller.

❚ Long-term reliability

FAULT CLEAR^® is designed to have a long service life by selecting reliable materials and parts. Bushings are made of Hydrophobic Cycloaliphatic Epoxy (HCEP) with silicon sheds for high UV environments.
