| Series Features |
| COKP Series AC OVERCURRENT |
| Series Description: Current sensing relays can be used in several applications where protection of sen- sitive or expensive equipment against over or under current conditions is required, such as detecting (sensing) conveyor jam-up conditions, machine tool wear, no load conditions or monitoring status of heater or lamp loads. The COKP 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 Selec- tion Table below. An external current transformer can be used to extend the range of these products. 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. |
