The Time Mark B263 3-Phase Monitor continuously monitors 3-phase power systems for phase loss, low voltage, and phase reversal. The monitor consists of a solid-state sensing circuit, driving an electromechanical relay. The D263 model offers 208/240VAC of nominal AC voltage, 160-240V adjustment range, 60Hz frequency, automatic reset, and 1.5W power consumption.

Applying correct voltage and phase rotation energizes the relay. When properly adjusted, a fault condition will cause the relay to de-energize, even when regenerated voltage is present.

The Model 263 does not require a neutral connection and can be used on Wye or Delta systems. Each of the five different voltage ranges is adjustable to allow the monitor to be set for existing conditions. NORMAL and TRIP LED indicators are provided to aid in adjustment and system troubleshooting.
