The Time Mark 257BM 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 257BM model offers manual reset, 208/240 VAC of nominal AC voltage, red case color, 160-240VAC adjustment range, 60Hz frequency, and 2.4W 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 257 series 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 in adjustment and system trouble-shooting.
