Product DescriptionThe 3-phase monitor continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, it 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 with one SPDT and one SPST contact. 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 it will automatically reset. Does not require a neutral connection and can be used with WYE or DELTA configured systems. Adjustment ranges are sufficiently wide to allow for proper adjustment to existing conditions. Two LED indicators are provided to aid in adjustment and system troubleshooting.
