The Red Lion APMR Phase Loss monitor helps protect 3-phase equipment from destructive line conditions. Specifically, it detects Phase Reversal, Phase Loss, Phase Unbalance and Low Voltage. All of these conditions, except for Phase Reversal, produce excessive heating of motor windings, causing immediate or cumulative damage to the motor. Phase Reversal will cause a motor to operate in the reverse intended direction, possibly damaging the machinery.

The output is SPDT relay and LED. The relay is typically connected in series with a motor contactor coil to inhibit motor start or to disconnect the motor in the presence of a fault condition. The relay automatically resets when the fault clears. The relay is typically used in a latching configuration so the motor has to be restarted after the fault is cleared. The LED illuminates green when all conditions are normal - no fault. When the LED is green, the relay is energized. When a fault occurs, the LED turns red and the relay is de-energized. If phase loss occurs on L1 or L3, the LED turns off and the relay is de-energized.

There are 3 models available: 230 ACV, 380 ACV and 480 ACV. The 230VAC model is used with 208, 220, 230 and 240 VAC rated equipment. The 380VAC model is used with 380 and 415 VAC rated equipment. The 480VAC model is used with 440, 460 and 480VAC rated equipment. The electrical connection is 3-wire Delta or WYE configurations.
