Description: A257B-480VAC 3PH PWR Mon
The Model 257 Continuously Monitors 3-Phase Power Lines For Abnormal Conditions. When Properly Adjusted, The Model 257 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 De-Energize The Relay. When The Fault Is Corrected, The Monitor Will Autom

Long Description: The Model 257 continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the Model 257 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 de-energize the relay. When the fault is corrected, the monitor will autom
