AC Overcurrent

CO Series

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 fi xed
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 (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.
