The Model 257 continuously monitors 3-phase power lines for abnormal onditions. When properly adjusted, the Model 257 monitor will detect phase loss on a oaded 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.Connects via an 8 pin octal baseFor use on 160-240Vac, 60HzTime Mark, Corp. 257B
