Three Phase Monitor

Operation

When proper voltages are connected to the phase monitor, the internal relay energizes, the indicator lamp illuminates, and power application to the load is enabled. Any abnormal condition will cause the internal relay to de- energize, the indicator lamp will extinguish and power will be removed from the load until conditions return to normal. These units can be used on Delta or Wye systems, 50/ 60 HZ. Neutral wires are NOT required.
