Overview

Power Monitor, 3-Phase, 480 Volt AC, 380 - 480 Volt AC Range, 3.7 Watt per Phase, Phase Loss or Reversal, Under Voltage, 10 Amp, Single Pole, Double Throw Contacts, Yellow, Auto Reset
The Model 258 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. 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 deenergize the relay. When the fault is corrected, the monitor will automatically reset (a manual reset version is also available).
