2 AC OVERCURRENT & UNDERCURRENT CAH, COH & CUH Series current sensing relays encapsulated Monitors AC current Can be used as either an overcurrent or undercurrent relay Three separate adjustable Fault Trip ranges covering amperes Built-in current transformer allows easy access & multiple loops for increased sensitivity Adjustable time delay on fault trip LED indicates fault condition 10A SPDT output contacts Encapsulated for protection in harsh environments The CxH Series is an AC current sensing relay that is available in three versions: CAH Series--can detect either an overcurrent or undercurrent fault (selectable); COH Series--overcurrent only; and CUH Series--undercurrent only. The currentcarrying wire is run through the built-in current transformer and can be looped multiple times for greater sensitivity. These relays include user-adjustable settings for Fault Trip & Time Delay on Fault Trip as well as an LED to indicate fault condition. The encapsulated construction offers protection in harsh environments. Applications such as monitoring for locked rotor or load loss condition, open heater or lamp, and process control are perfect for these products. Overcurrent Sensing After input voltage is applied & the sensing delay on power-up (t S ) is completed, the unit will begin sensing for a fault condition. A fault will occur when the monitored AC current (I) goes above the Fault Trip setting & remains above the Reset level for a period longer than the adjustable time delay period (t). The LED will turn ON immediately and the relay will energize after the time delay on pick-up (t) is completed. The relay will de-energize & the LED will turn OFF when the monitored AC current goes below the Reset level. Undercurrent Sensing After input voltage is applied & the sensing delay on power-up (t S ) is completed, the unit will begin sensing for a fault condition. A fault will occur when the monitored AC current (I) goes below the Fault Trip setting & remains below the Reset level for a period longer than the adjustable time delay period (t). The LED will turn ON immediately and the relay will energize after the time delay on pick-up (t) is completed. The relay will de-energize & the LED will turn OFF when the monitored AC current goes above the Reset level.

4 AC STANDARD CM Series current sensing relays plug-in Monitors AC currents Three separate current monitoring ranges covering 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 (with appropriate socket) sales@macromatic.com 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. 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, 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 fi xed at 100ms.

5 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 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.

6 AC UNDERCURRENT CU Series The CU Series is used to detect an undercurrent condition. The drop-out 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 for undercurrent conditions Three separate current monitoring ranges covering amperes External CT can be used to extend ranges Adjustable Drop-out Setting with Fixed Pick-up Setting Adjustable time delay of seconds on drop-out LED indicates output relay status Choice of compact 8 Pin SPDT or 11 Pin DPDT plug-in case 10A output contacts (with appropriate socket) The pick-up current setting is fi xed at +5% of the selected drop-out setting. The relay will energize when the monitored AC current is above the pick-up setting. It will de-energize when the monitored AC current is below the drop-out setting for a period longer than the adjustable time delay (t) of seconds.
