CJX2-4011 AC Contactor 40A with NO and NC Auxiliary Contacts
The CJX2-4011 is the 40A frame of the CJX2 range, carrying one NO and one NC auxiliary contact for interlocking and status feedback. It switches 18.5kW motors at 380/400V and takes a 60A thermal current, so it suits compressors, hoists and larger machine tool drives.
Main Contacts
AC-3 rating is 40A at 380/400V and 34A at 660/690V. AC-4 rating is 18.5A at 380V and 9A at 660V for plugging and inching duty, with motor ratings of 11kW at 220V, 18.5kW at 380/400V and 30kW at 660V.
Auxiliary Pair
Two auxiliary contacts, one NO and one NC, are rated 10A thermal at AC-15 380V and DC-13 220V, with 360VA AC-15 control capacity. The pair supports interlocking between contactors and gives a positive feedback signal to the controller.
Coil Loading
Coil voltages run AC 36V, 110V, 127V, 220V and 380V. Closing power is 200VA, holding power 20VA and coil loss 6W to 10W, with pick-up at 85% to 110% Us and drop-out at 20% to 75% Us.
Life and Matching Parts
Electrical life is 800,000 operations at AC-3 and 150,000 at AC-4, mechanical life 8 million, at up to 600 operations per hour. Wiring capacity is 10mm², matching RT16-63 fuses and JR28-93 thermal relays. Send the motor rating and coil voltage and we will confirm the model.
