Frequently Asked Questions
What is NMB-MAT 3615KL-05W-B60?
NMB-MAT 3615KL-05W-B60 is a 24 VDC brushless axial cooling fan from the 3615KL family. Multiple commercial sources identify it with a 92 × 92 × 38 mm frame, 0.55 A current rating and two-wire electrical connection. It is commonly marketed for industrial inverter and electronic equipment cooling.
What is the rated voltage of 3615KL-05W-B60?
The nominal supply voltage is 24 VDC, consistently identified in commercial product records. A B60-specific manufacturer operating voltage range has not been independently confirmed. Before installation, use the full fan label and applicable equipment documentation to verify the DC supply requirements.
What are the dimensions of 3615KL-05W-B60?
The documented fan frame measures 92 mm wide, 92 mm high and 38 mm deep. This is commonly described as a 9238 cooling fan. Matching dimensions alone does not establish compatibility, so mounting hole positions and cable clearance should also be checked.
What is the rated current of 3615KL-05W-B60?
Multiple independent supplier records identify the B60 model as a 24 VDC fan rated at 0.55 A. This differs from the lower-current B50 model. The actual fan label should be checked to confirm the electrical rating of the supplied unit.
What is the input power of 3615KL-05W-B60?
A nominal electrical input of 13.2 W follows from multiplying 24 VDC by 0.55 A. An independent supplier also lists 13.2 W. This value is appropriate for preliminary electrical-load identification, but actual running power may vary under operating conditions.
What is the fan speed of 3615KL-05W-B60?
One supplier specifies 4500 RPM for the B60 configuration. However, the published standard NMB 3615KL catalog lists several speed classes without separately establishing a B60 rating. Therefore 4500 RPM should be treated as a supplier-reported value rather than a fully verified manufacturer rating for every assembly.
What is the maximum airflow?
An independent supplier reports 83.9 CFM, approximately 2.38 m³/min. A matching exact-model manufacturer airflow curve has not been independently located. The figure should be confirmed with the manufacturer or verified by the equipment specification when airflow performance is critical.
What is the maximum static pressure of 3615KL-05W-B60?
A manufacturer-verified maximum static pressure value for the exact B60 configuration has not been established. Static pressure ratings from 3615KL-05W-B50 or 3615KL-05W-B70 should not be substituted because the models have different electrical and cooling characteristics.
What bearing type does 3615KL-05W-B60 use?
Commercial listings describe ball bearing construction. Published 3615KL series documents also identify ball bearings in standard configurations. However, the exact B60 assembly and its life expectancy should be verified if bearing design or service life is a specific purchase requirement.
Does 3615KL-05W-B60 have two wires?
Yes. Commercially documented B60 versions feature two wires for DC power. Red is identified as the positive supply connection and black as negative. Certain versions use a two-pin E1-style plug, while others may have different terminations. The supplied connector should match the installed equipment.
What is the difference between 3615KL-05W-B60 and 3615KL-05W-B50?
Both belong to the 24 VDC 3615KL family and share a nominal 92 × 92 × 38 mm frame. The manufacturer-documented B50-P00 version is rated at 0.24 A, 4000 RPM and 76.2 CFM. Commercial B60 listings identify 0.55 A, with one supplier reporting 4500 RPM and 83.9 CFM. These differences mean the two models should not be considered automatically interchangeable.
What should be checked before ordering 3615KL-05W-B60?
Verify the exact model number 3615KL-05W-B60, any additional assembly markings such as EQ1, nominal 24 VDC voltage, documented 0.55 A current rating, 92 × 92 × 38 mm dimensions, two-wire arrangement, connector type, polarity, mounting hole spacing, airflow direction and equipment compatibility. For applications with strict cooling performance requirements, obtain verified fan speed, airflow, static pressure and operating temperature specifications for the exact assembly. Do not assume that B50, B60 and B70 models are direct replacements for one another.
