23
3-Phase Monitor with Trip and Restart DelaysRead moreThe Model 23 is a microcontroller-based universal 3-phase monitor for protecting 3-phase motors from abnormal power conditions. It can detect under voltage, over voltage, voltage unbalance, reverse phase, and single-phasing even when regenerated voltage is present. The Model 23 includes adjustable trip and restart delays to prevent nuisance tripping during power fluctuations and short cycling in compressor applications. The LED status indicators and adjustment pots for Voltage Adjustment, % Unbalance, Restart Delay and Trip Delay are mounted on the front of the unit for easy access.The Model 23 has 2 contacts (1 SPDT, 1 Normally Open SPST). It can be used on either Wye or Delta systems and does not require a neutral connection.
All versions of the Model 23 are available with optional gold flashed silver contacts for low current applications.
