Note: Image shown is for illustration purpose only, actual product may vary 3-Phase monitor Automatic reset Nominal AC(phase to phase): 415VAC Case color: Yellow Adjustment range: 340-440VAC Frequency: 50Hz Power: 3.3W ABS plastic cover 8-pin socket mounting (sold separately) The Time Mark EX257B-415VAC/50HZ 3-Phase Monitor continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the unit will detect phase loss on a loaded motor even when regenerated voltage is present. The EX257B-415VAC/50HZ model offers 415 VAC of nominal AC voltage, yellow case color, 340-440VAC adjustment range, 50Hz frequency, and 3.3W power consumption.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 (a
