The SEL-BTRIP is designed for 4,160 V to 69 kV overhead system applications. It is quick and easy to apply using a single hot stick. A super bright flashing LED display provides clear indication of an overcurrent event. The SEL-BTRIP is completely powered by a 3.6 V high-capacity 8.5 Ah lithium battery with a 20-year shelf life.
The SEL-BTRIP is available in five program selection choices, each containing four field-selectable nominal trip ratings. Specify which program setting is to be factory-set, or select/change the nominal trip rating in the field using the CRSRTT tool. The SEL-BTRIP’s versatility and efficiency make it useful in locating momentary fault occurrences or as a permanently installed fault indicator. No maintenance is required.
Troubleshooting for Overhead and Underground Lines—Field-select one of four fixed trip values: 50 A, 100 A, 200 A, or 400 A. Use lower trip values at the ends of circuits due to lower available fault currents. Use higher nominal trip ratings near the substation. Conveniently keep SEL-BTRIPs on the truck. Temporarily apply the SEL-BTRIP at key points along the circuit to troubleshoot a fault. Remove the SEL-BTRIP after the fault is located.
Timed-Reset Intervals—Manually reset the SEL-BTRIP using the CRSRTT magnet test tool so that units can be reapplied to another part of the circuit to further narrow down the faulted circuit section. If you don’t have the opportunity to reset the units, designate a four-hour timed-reset interval, and the units will clear after four hours to conserve battery life.
