Product Specifications

Review the technical data used for replacement matching, procurement comparison and engineering approval.

External seller reference — verify supplied version: The seller reference shows NMB BM5125-04W-B59 labelled T11 and 12V DC 0.32A. The full model, T11 marking, input and corresponding blower housing are visible in both the source and historical listing photographs. Both show red/black/pale three-wire leads. The source shows a pale three-position housing; the historical connector is partly outside the frame, so its complete shape, pitch and keying are not established. Source additional marking 1073163 differs from historical 7073163; their meanings and equivalence have not been verified. Photographic identity and prior third-party processing history have not been independently verified. This is not an untouched-original recovery or proof of current shipping stock, supplied condition, measured dimensions, equipment fit or interchangeability. Confirm the actual complete label, supplied harness, full connector, wire order, pin assignment and mounting before ordering. The historical listing photographs are retained in store records outside this gallery.
