AC Under Current Monitor (CMU Series)
The CMU Series AC Under Current Monitor is used to detect UNDER CURRENT conditions. The internal relay is energized (Pick-up) when the monitored current is above the preset trip point. The relay de-energizes (Drop-out) when the current falls below the trip point for longer than the adjustable delay. The delay is incorporated to prevent nuisance tripping caused by momentary line dips. The relay re-energizes when the current rises 5%above the Drop-out trip point for longer than 0.1 seconds. The relay has the automatic reset feature. An external CT may be used to extend the range of the Current Monitor.
