Function	Phase Monitor
Measuring Range	160-240 VAC
Monitoring Function	Phase Monitor
Mounting Type	Socketable
Number of Pins	8 Pin
Primary Type	Monitoring Relays
Product Description	Continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the 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 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 (a manual reset version is also available). Does not require a neutral connection and can be used with Wye or Delta systems. Voltage ranges are sufficiently wide to allow for proper adjustment to existing conditions. Both "TRIP" and "NORM" condition indicators are provided to aid an adjustment and system trouble-shooting.
