Current Monitoring Relays

CO Series Overcurrent

Macromatic Products Menu :

The CO Series is used to detect an overcurrent condition. The pick-up current setting is user-adjustable within one of three ranges as shown in the Product Selection Table below. An external current transformer can be used to extend the range beyond 10 amperes.

Choose between a fixed drop-out current setting at 95% of the selected pick-up setting or an adjustable drop-out setting of 50-95% of the selected pick-up setting. The relay will energize when the monitored AC current is above the pick-up setting for a period longer than the adjustable time delay of 0.1-10 seconds. This delay prevents nuisance tripping caused by inrush currents. It will de-energize when the monitored AC current is below the drop-out setting.

  • Monitors AC single phase currents for overcurrent conditions
  • Adjustable time delay of 0.1-10 seconds on pick-up
  • Three separate current monitoring ranges covering 0.1 - 10 amperes
  • External CT can be used to extend ranges
  • Adjustable Pick-up Setting with either Fixed or Adjustable Drop-out Setting
  • Choice of compact 8 Pin SPDT or 11 Pin DPDT plug-in case
  • 10A output contacts
