BTRI_IR Fault Indicators are typically installed on overhead taps, near underground transitions, at overhead midfeeder disconnects, and near unfused taps or riser poles. The BTRI_IR Fault Indicator's 1 ms response time and true timed reset functionality make it especially useful for locating momentary faults. Nominal trip ratings are factory-set to your specification. Specify an LED flash-clearing time that best coordinates with line crew response times.
A nonreplaceable battery version is available, which requires no maintenance. Manually test, activate, or clear a flashing LED using the CRSRTT tool (sold separately). Single hot stick installation and a super bright LED display make the BTRI_IR a smart choice.
Applicable on overhead taps, overhead-to-underground transitions, and overhead midfeeder disconnects.
No minimum load current is necessary for reset.
Time delay between system restoration and reset makes the BTRI_IR a good choice for troubleshooting momentary faults.
The inrush restraint feature allows coordinated integration with automatic reclosing schemes, preventing false tripping.
