SKU CH-SXAF-PK59N MPN 4715KL-05W-B49Size

A 12038 mm DC24V case fan with double ball bearing and three-line wiring for industrial and server cooling

  • Reliable long-life operation with high-precision double ball bearing
  • Stable 24 V DC power draw at 0.46 A current
  • Compact 120 mm square frame fits tight chassis spaces
  • Three-wire lead allows speed monitoring or two-wire conversion
  • Suited for industrial, medical and rail cooling applications

Industrial DC24V cooling fan

The NMB 4715KL-05W-B49Size is a 120 mm square by 38 mm thick axial fan built for 24 V DC systems in elevator inverters, CNC machines, network chassis and similar industrial equipment. It targets engineers and integrators who need a replacement unit with the original mounting footprint and voltage rating.

Three-wire connection and ball-bearing mounting

The fan ships with a three-line lead that can be reconfigured to two lines if the control circuit only requires power and ground. Double ball bearings support the rotor, so the installer must avoid side loads during fitting and ensure the screw holes align with the 120 mm pitch to prevent vibration noise.

Sustained operation in continuous-duty environments

Rated at 0.46 A, the motor is designed for constant running in frequency-converter cabinets and rail-vehicle drives rather than short bursts. The bearing construction and 24 V supply maintain stable airflow over long shifts without the thermal throttling seen in lower-voltage desktop fans.

Questions about this item

How can I confirm the 120*120*38mm fan is running correctly after installation?

Measure the current draw at the 3-line connector; it should read around .46 A at DC 24 V, and the double ball bearing should spin without audible roughness.

What comes in the box and what must be sourced separately for the 4715KL-05W-B49?

The package contains the 12038 axial fan with its three-wire lead; mounting screws, a 24 V power supply and any PWM controller are not included.

Which version of the NMB 4715KL-05W-B49 should I choose for a 24 V industrial chassis?

Select the DC 24 V, .46 A model with the standard three-line wiring; a two-line variant can be requested if your controller only accepts tach and power leads.
