CJX2-F225 4P High Ampere AC Contactor 225A
The 4P version of the CJX2-F225 switches the neutral with the three phases, which TN-S and TT installations need when the neutral has to be isolated together with the load. Current ratings are the same as the three pole model, and the body is 40mm wider at the A dimension.
Pole Configuration
Four main poles, all rated 225A in AC-3 duty at 380/400V and 137A at 660/690V. Conventional thermal current in AC-1 duty is 275A. The fourth pole carries the neutral, not an auxiliary signal.
Motor Capacity
Three-phase cage motors are rated 110kW at 380/400V and 132kW at 660/690V, and the neutral pole is rated for the neutral current of the same load.
Footprint
The A dimension grows from 171mm on the three pole model to 211mm here, with the same B and C dimensions and the same M10 main pole terminals. Panels laid out for the three pole F225 need about 40mm more width.
Life and Protection
Electrical life is 1 million AC-3 operations and mechanical life 6 million, at up to 600 operations per hour. The matched fuse is an NT2 link rated 315A. Tell us the neutral current and coil voltage and we will confirm the model.
