120 mm 24 V case fan

This 120 mm fan operates at 24 V and draws 0.70 A, making it suitable for industrial control cabinets and similar enclosures. It uses genuine double ball bearings for reliable rotation and is built to the 1238HH24B-WDB specification. The frame measures 120 by 120 by 38 mm. The part matches ABB reference 3HAC029105-002 and ships new with its plug attached.

Who this suits

Engineers maintaining ABB robot controllers or other 24 V DC cooling slots will find a direct-fit replacement. Technicians who need a 38 mm thick axial fan with a factory-fitted connector can install it without rewiring.

Who should look elsewhere

Builders working on standard 12 V PC chassis should choose a 12 V model instead. Anyone requiring PWM speed control or a different connector pin-out will need a different fan.

Capacity and headroom

At 24 V and 0.70 A the fan delivers steady airflow for controller cabinets and comparable industrial housings. The double ball bearing supports continuous duty in warm environments. It is not designed for variable-speed PC curves or voltages outside the rated 24 V supply.

Questions about this item

Will this 24 V fan run from my standard PC 12 V header?

No, it requires a 24 V supply; a 12 V header will not power it.

Can I replace the 120 mm fan in my older ABB cabinet that used the 3HAC029105-002?

Yes, the 1238HH24B-WDB matches the 120×120×38 mm footprint and plug of that part.

How do I confirm the double ball bearing is spinning correctly after install?

Listen for smooth, steady rotation and verify 0.70 A draw at 24 V with a multimeter.
