CMO-120-ASE-5 ATC Diversified Electronics

The CMO Series is used to detect OVER CURRENT conditions. Theinternal relay energizes (Pick-up) when the monitored current exceedsthe preset trip point for longer than the adjustable time delay. The delayis incorporated to prevent nuisance tripping caused by motor inrushcurrents. The CMO has an automatic reset feature. The internal relay deenergizes (Dropout) when the current drops 5% below the preset trip for longer than 0.2 seconds.An External CT may be used to extend the range of the Current.
