CJX2-2510 3 Pole AC Contactor 25A with One NO Contact

The CJX2-2510 carries a 25A AC-3 rating on three main poles and adds one normally open auxiliary contact for the control circuit. It is the size most often specified for 11kW motors in pumps, compressors and packaging lines.

Three Main Poles

AC-3 rating is 25A at 380/400V and 18A at 660/690V, backed by a 40A thermal current. AC-4 rating is 8.5A at 380V and 4.4A at 660V, which keeps reversing and inching duty inside the contact rating.

Auxiliary Contact

The 10 suffix adds one NO auxiliary contact, rated 10A at AC-15 380V and DC-13 220V with 360VA AC-15 control capacity. It can hold a seal-in circuit or drive a panel lamp without a separate relay.

Motor and Coil Data

The frame controls 5.5kW at 220V, 11kW at 380/400V and 15kW at 660V motors. Coil voltages cover AC 36V to 380V, closing at 70VA and holding at 8VA, with pick-up at 85% to 110% Us.

Life and Wiring

Electrical life is 1 million operations at AC-3 and 200,000 at AC-4, mechanical life 10 million, at up to 1200 operations per hour. Wiring capacity is 4mm², with RT16-40 fuses and JR28-25 relays as matching parts. Send the motor rating and coil voltage for a quote.
