Combination Display Provides Optimal Indication—Apply this dual-display faulted circuit indicator for excellent visual indication, even in low-light conditions. The combination BEACON LED and target display provides optimal night and day indications. The Daylight Restraint feature conserves battery life by activating the LED only in reduced ambient light conditions. Use at strategic intervals along overhead conductors and at midfeeder disconnects to minimize fault-finding time and optimize reliability statistics. The inrush restraint feature prevents false tripping during recloser operations, and the unit automatically resets upon restoration of system voltage. The mechanical target and sensor remain operational regardless of the amount of charge on the battery.
Low Load Current—Install a BER BEACON Electrostatic Reset where there is insufficient load current to power a current reset fault indicator. These sensors use voltage for power and reset.
Replaceable Battery—Replace the industry-standard battery by hand. No tools required.
