AC STANDARD CM Series The CM Series is used to detect either an overcurrent or undercurrent 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. current sensing relays | plug-in Monitors AC currents 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 LED indicates output relay status Choice of compact 8 Pin SPDT or 11 Pin DPDT plug-in case 10A output contacts 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, and will de-energize when the monitored AC current is below the drop-out setting. The time delay on both pick-up and drop-out is fixed at 100ms.
