Time Mark B258B - 3-Phase Monitor, Auto Reset, 120VA

3-Phase Monitor Automatic reset Nominal AC voltage: 120VAC Case color: Gray Adjustment range: 85-120 VAC Frequency: 60Hz Power consumption: 1.4W Detects phase loss, low voltage, phase reversal ABS plastic cover The Time Mark B258B 3-Phase Monitor continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the Model 258 monitor will detect phase loss on a loaded motor even when regenerated voltage is present. The B258B model offers automatic reset, 120VAC nominal AC voltage, gray case color, 85-120VAC adjustment range, 60Hz frequency, and 1.4W 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 manual reset version is also available).The Model 258 series does not
