The Time Mark 2002Y-277/480 3-Phase Voltage Unbalance Monitor is designed to continuously monitor a three-phase line with a neutral connection for unbalanced voltage conditions. The unit offers 277 VAC phase-neutral voltage, 480 VAC phase-phase voltage, ± 15% voltage range, and 2.0W power consumption.

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 the main power can be restored without resetting breakers.

The solid-state sensing circuit drives an internal electromechanical relay. Indicator lights on the monitor show when the voltage balance is within an acceptable range, when an unbalance exists, and when the relay is actually tripped.
