CJX2-0910 AC Contactor 9A for Three-Phase Motor Control

The CJX2-0910 is a 9A AC contactor built for switching three-phase motors in machine control panels. The 9A AC-3 rating at 380/400V covers 4kW motors, and 6.6A at 660V carries the same duty on higher voltage supplies.

Motor Switching Duty

The AC-3 rating reaches 9A at 380/400V, driving 2.2kW at 220V, 4kW at 380/400V and 5.5kW at 660V. AC-4 rating sits at 3.5A for plugging and inching duty, and the 20A thermal current leaves margin for motor inrush.

Coil and Control

Coil options cover AC 36V, 110V, 127V, 220V and 380V. Pick-up at 85% to 110% Us and drop-out at 20% to 75% Us keep the contactor stable when supply voltage swings. Closing power is 70VA, holding power 8VA, and coil loss runs 1.8W to 2.7W.

Contacts and Life

Three main poles carry the motor current, and one NO auxiliary contact rated 10A at AC-15 380V handles the control circuit. Electrical life reaches 1 million operations at AC-3 and mechanical life 10 million, at up to 1200 operations per hour.

Panel Matching

Insulation voltage is 690V and wiring capacity is 1.5mm². The contactor pairs with RT16-20 fuses and JR28-25 thermal relays for short circuit and overload protection. Send your motor rating and coil voltage for a quote.
