  • 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 Automatically Reset
  • Made in USA
