CJX2-F400 4P High Ampere AC Contactor 400A

CJX2-F400 4P High Ampere AC Contactor 400A

Rated current: CJX2-F400 4P High Ampere AC Contactor 400A, 400A in AC-3 duty at 380/400V and 303A at 660/690V.

Poles: Four poles, so the three phases and the neutral are switched by one device.

Thermal current: 450A conventional thermal current in AC-1 duty.

Motor power: 200kW at 380/400V and 250kW at 660/690V for three-phase cage motors.

Endurance and size: 6 million mechanical operations, 600 per hour, NT3 630A fuse, 261mm A dimension against 215mm on the three pole version.

CJX2-F400 4P High Ampere AC Contactor 400A

The 4P version of the CJX2-F400 switches the neutral together with the three phases, as TN-S and TT installations require when the neutral must be isolated with the load. Ratings match the three pole model and the body is 46mm wider at the A dimension.

Pole Configuration

Four main poles, all rated 400A in AC-3 duty at 380/400V and 303A at 660/690V. Conventional thermal current in AC-1 duty is 450A. The fourth pole carries the neutral.

Motor Capacity

Three-phase cage motors are rated 200kW at 380/400V and 250kW at 660/690V, and the neutral pole is rated for the neutral current of the same load.

Footprint

The A dimension grows from 215mm on the three pole model to 261mm here, with the same B and C dimensions and the same M10 main pole terminals. Allow about 46mm more width in the panel.

Life and Protection

Mechanical life is 6 million operations with up to 600 AC-3 operations per hour. The matched fuse is an NT3 link rated 630A. Tell us the neutral current and coil voltage and we will confirm the model.
