MGT4012MB-R20 Equipment Cooling Fan
Select by complete product identification. The photographed PROTECHNIC ELECTRIC label identifies MGT4012MB-R20 and shows 12V and 0.11A. Confirm the equipment requirements before choosing a replacement.
Read the Original Product Label
Original label reference: PROTECHNIC ELECTRIC; MGT4012MB-R20; 12V; 0.11A. Preserve the complete -R20 suffix. The original photograph, rather than the retouched hero image, is the identity reference.
Start with the Electrical Requirements
The pictured label shows 12V and 0.11A. A voltage match alone does not establish compatibility. Confirm the equipment supply and the exact fan connection. No speed, power, airflow or noise value is inferred.
Check the Complete Mechanical Fit
Compare the actual frame width, height and depth, mounting-hole arrangement, cable exit and service clearance with your equipment. The product images are not dimensional drawings, and no size is inferred from the model code.
Inspect the Original Lead and Connector Photo
The original photograph shows red, black and white leads and a white connector housing. Confirm the connector shape, keying, orientation and equipment wiring diagram. No PWM, tachometer, alarm function or pinout is inferred from wire colour or count.
Match the Equipment, Not Just the Voltage
Check three things together: complete MGT4012MB-R20 identity, mechanical fit and the electrical interface. A matching voltage or similar connector shape is not a universal equipment compatibility guarantee. No specific H3C switch fit is established.
MGT4012MB-R20 - Before You Order
Is the complete model important?
Yes. Match MGT4012MB-R20, including -R20. A similar size or a different suffix is not proof of interchangeability.
What ratings can be read from the photo?
The original motor label shows 12V and 0.11A. These are photographed label markings, not independent test results.
Does the third wire mean PWM or alarm?
Not necessarily. The exact signal function and connector pin assignments are not established here.
Is this guaranteed to fit an H3C switch?
No exact H3C model or FRU match is established. Confirm the equipment parts reference and interface before ordering.
Are screws, adapters or multiple fans included?
Product photos do not establish package contents. Confirm the selected offer and supplied quantity separately.
