phase unbalance monitoring relay / panel-mount / three-phase
120 - 480 V | 2002Y series
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.
