Time Mark 158BR - 3-Phase Monitor with LED indicator and Timer, 208/240VAC, 160-260VAC, 60Hz, .5W

The Time Mark 158BR is a 3-phase monitor with an additional LED indicator for RESTART and a 5-minute short cycle timer, to delay restarting the motor. The unit offers 208/240VAC input voltage, 160-260VAC adjustment range, 60Hz frequency, and .5W power consumption. The unit continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the Model 158 monitor will detect phase loss on a loaded motor even when regenerated voltage is present.

This device consists of a solid-state voltage and phase-angle sensing circuit, driving an electromechanical relay. When the correct voltage and phase rotation are applied, the internal relay will energize. A fault condition will de-energize the relay. When the fault is corrected, the monitor will automatically reset.

The Model 158 series does not require a neutral connection and can be used with Wye or Delta systems. Voltage ranges are sufficient to allow for proper adjustment to existing conditions. A front-mounted LED failure indicator is provided.
