4-POLE CONTACTORS

4-Pole Contactors for Neutral Switching and Two-Circuit Control

A four-pole contactor has a fourth set of main contacts, rated for the same current as the other three. That fourth pole is what lets one device switch three phases plus neutral, or two separate single-phase circuits at once.
The CJX2 04 series covers 12, 25, 65 and 95 A with 690 V rated insulation, and the CJX2-F frames add 185, 225 and 400 A where the load is heavier. Coil options are AC 24, 36, 48, 110, 220 and 380 V.
The common mistake is using the fourth pole for a neutral that carries no current and assuming it is rated for the full load. It is rated, but it still has to be sized for whatever current actually flows through it. Units carry CE and CCC marking.

4-Pole Contactor Models

Four CJX2 04 frames cover 12 A to 95 A and three CJX2-F frames extend the range to 400 A. Confirm the coil voltage and the auxiliary contacts before ordering.
Model Current Coil options Typical use
CJX2-1204 12 A AC 24–380 V Two small single-phase circuits
CJX2-2504 25 A AC 24–380 V 3-phase plus neutral
CJX2-6504 65 A AC 24–380 V Distribution boards
CJX2-9504 95 A AC 24–380 V Larger feeders
CJX2-F185 4P 185 A AC coils High-current feeders
CJX2-F225 4P 225 A AC coils Main switching
CJX2-F400 4P 400 A AC coils Heavy duty switching

Wiring notes

  • On a three-phase motor the fourth pole is usually spare; leave it unconnected rather than using it as an earth, because the contactor is not an earthing device.
  • For two single-phase circuits, check that both poles in each pair carry the same current; the rating applies per pole, not per pair.
  • US and Canadian panels often ask for a 120 V coil; our closest standard coils are 110 V and 220 V, so confirm the control transformer before ordering.
Send the panel drawing and the coil voltage, and we will confirm the frame, the coil code and the auxiliary block.
NEUTRAL SWITCHING

Where the Fourth Pole Earns Its Cost

Per Pole, Not Per Pair

Each pole is rated individually. Both poles feeding one single-phase circuit must be able to carry that current.

Not an Earth

The fourth pole is a switching contact. The protective earth stays a separate, unswitched conductor.
COMMON QUESTIONS

Frequently Asked Questions

It switches three phases plus neutral, or two separate single-phase circuits, through one device. It is used where the neutral has to be isolated with the phases, and in panels that control two loads together.
