SEL-BTRI

Overhead BEACON Timed-Reset Fault Indicator

SEL recommends selecting the SEL-AR360 and SEL-AR Overhead AutoRANGER Fault Indicators in place of the SEL-BTRI.

SEL will continue to support the warranty on the SEL-BTRIP and SEL-BTRI_IR.

Momentary Fault Troubleshooting—The timed-reset feature makes the SEL-BTRI ideal for troubleshooting momentary faults.

Recloser Coordination—The inrush restraint feature prevents false tripping during recloser operations by not responding to temporary current surges caused by transformer re-energization inrush (circuit re-energization), making it ideal for use with automatic reclosing schemes.

Timed-Reset Intervals—A factory-set 2-, 4-, or 8-hour timed-reset interval will automatically reset the SEL-BTRI. You can also manually reset the units using the CRSRTT magnet tool.

Industrial Backfeed—Circuits feeding large industrial equipment and rotating machinery can contribute energy into a fault past the FCI’s location within the fault path. Sometimes this energy is sufficient to reset a current or voltage reset-type FCI, misleading crews searching for a fault. You can use the SEL-BTRI in applications with backfeed to ensure FCIs in the fault path continue to display their fault indication for the timed-reset period, regardless of the duration or magnitude of the backfeed condition.
