3 Phase Monitor SPDT electromechanical relay Neutral is not required LED indicators CSA Certified

The Model 246 3-Phase Monitor is designed to continuously monitor 3-phase power lines for phase loss, phase reversal, low voltage and high voltage. This device features solid-state voltage and phase angle sensing circuits, which drive a SPDT electromechanical relay. A neutral is not required, allowing the Model 246 to be used with either Wye or Delta systems.

Three versions of the Model 246 cover the 120 and 208/240VAC, 60Hz and the 380VAC, 50Hz. In addition, the models A246 and B246 are now CSA Certified.

Each option on the Model 246 monitor is adjustable throughout its operating range. The adjustment pots and LED indicators for OVER VOLTAGE and UNDER VOLTAGE are mounted on the front of the unit for easy access.
