3 Phase Monitors from Time Mark

This line of 3-Phase Monitors all use a unique voltage and phase angle sensing circuit which allow the devices to monitor conditions that would be harmful to motors and other machinery. All will detect loss-of-phase, low or high voltage and reverse phase. Differences in the models are generally limited to the type of enclosure, output contact arrangements and the addition of restart or trip delays.
