CJX2-18 AC Contactor 18A for 7.5kW Motor Loads

The CJX2-18 switches three-phase motors up to 7.5kW at 380/400V from a compact three-pole frame. It fills the step between the 12A and 25A models in the CJX2 line, where panel space and wiring cost matter as much as breaking capacity.

18A Frame

AC-3 rating is 18A at 380/400V and 12A at 660/690V, with a 32A thermal current behind it. AC-4 duty is rated 7.7A at 380V and 3.8A at 660V, so inching and plugging stops stay inside the contact rating.

Motor Capacity

The contactor controls 4kW at 220V, 7.5kW at 380/400V and 10kW at 660V three-phase motors. Insulation voltage is 690V and wiring capacity 2.5mm², which suits small pumps, fans, conveyors and machine tool spindles.

Coil Circuit

Coil options run AC 36V, 110V, 127V, 220V and 380V. Closing power is 70VA, holding power 8VA and coil loss 1.8W to 2.7W, with pick-up at 85% to 110% Us and drop-out at 20% to 75% Us.

Life and Matching Parts

Electrical life reaches 1 million AC-3 operations and mechanical life 10 million, at up to 1200 operations per hour. Pair it with RT16-32 fuses and JR28-25 thermal relays. Tell us the motor rating and coil voltage and we will confirm the model for your panel.
