phase unbalance monitoring relay phase unbalance monitoring relay - 120 - 480 V | 2002Y series
  • Phase unbalance monitoring relay


  • Measured/monitored value:

    phase unbalance

  • Other characteristics:

    panel-mount, three-phase

  • Trigger voltage:

    Min.: 120 V

    Max.: 480 V


The Model 2002Y 3-Phase Voltage Unbalance Monitor is designed to continuously monitor a three-phase line with a neutral connection for unbalanced voltage conditions.

This device will only energize the relay if an unbalance exists. Zero volts on all three phases is considered a balanced condition. This allows the Model 2002Y to be used with shunt breakers, so that main power can be restored without resetting breakers.
