Overview

A microprocessor-based relay that provides versatility and control in

automatic circuit breaker reclosing.

Features

• Ability to resume reclosing sequence if control power is interrupted.

• Individually adjustable time-delayed reclosing attempts.

• Separate high speed pilot reclose input and output are available for

transmission reclosing applications.

• Self-monitoring circuitry with alarm output.

• Optional controls limit the duration of reclose command output and the

overall reclosing cycle.

• Optional contact inputs can be used to inhibit the reset timer, inhibit

all reclose timing, obtain an alarm prior to lockout, or permit a special

reclosing sequence.

Benefits

• Program up to four reclosure attempts with contact-selectable

reclosing sequences.

• Gain flexibility with individually adjustable time-delayed reclosing

attempts.

• Optional outputs provide control for tripping schemes and blocking

load tap-changer operation during reclosing sequences.

• Reduced battery load with low burden power supply.

• Easily perform in-case system and device tests using test paddles.
