FAULT CLEAR ®
T r i p l e - S i n g l e

A u t oR e c l o s e r

Our product contributes to improve “ Your Grid Reliability”.

▶Working directly with SEL controller
FAULT CLEAR® works directly with “SEL-651R-2” and 32-pin control cable for three-phase/triple-single
application and “SEL-351RS” controller with 10-pin control cable for single-phase application.

▶Pole-ready design
FAULT CLEAR® is also ready to “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 UVenvironments.

▶10-year warranty*
FAULT CLEAR® is designed to have a long service life by selecting reliable materials and parts,
which allows us to offer 10-year warranty at no extra cost.

FAULT CLEAR® has a high-speed mechanism.
Closing time

:38msec±10ms

Opening time

:14msec±10ms

High speed opening time leads to decrease clearing time.
It helps to achieve correct coordination with other equipment.
Type test result“Time-current tests”

FAULT CLEAR® has a high-precision mechanism.
Simultaneity of poles:less than 4msec

Bouncing duration of the main contacts :less than 3msec
Simultaneity of poles is important to avoid nuisance trip (51G).
And, also it helps to suppress switching surge.
