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.
Details
Some configurations, such as those with an LED or timed-reset feature, may contain a battery. For configurations with a battery, please see the lithium metal battery warning.
The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
