Description Of Function

The pick-up current setting is user-adjustable within the Monitored Current Range below. An external current transformer can be used to extend the range beyond 10 amperes. The drop-out setting is adjustable from 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 (t) 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.

Operation

The COKP Series is used to detect an overcurrent condition. The pick-up current setting is user-adjustable within one of three ranges: 0.1-1A, 0.5-5A, and 1-10A. An external current transformer can be used to extend the range beyond 10 amperes.

The drop-out setting is adjustable from 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 (t) 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.
