LINE VOLTAGE / PHASE MONITORS

ICM line voltage monitors continuously monitor incoming line voltage to provide superior motor protection from premature failure and damage due to voltage unbalance, high and low voltages, phase loss, phase reversal, faulty power, incorrect sequencing and/or rapid short cycling. Some models include LED indicators or LCD diagnostic displays to indicate the current system condition. Single phase line monitors provide high performance surge protection. They are suitable for rugged environments and protect against lightning power surges and voltage surges from air conditioners, generators or motors. All ICM line voltage monitors are quality made in the USA. Contact us for additional information or help finding a compatible line voltage monitor.
