Solution
Specify And Cross Reference
Most projects start with a part number from a catalogue that is no longer easy to buy. The first job is not quoting, it is confirming exactly what the existing part is.
Process
How It Works Step By Step
1Send What You HaveA part number, a photograph of the rating plate, or the busbar and cable dimensions. Email or WhatsApp both work.
2Identify The FrameThe cross reference library covers the Lovato, Rayleigh, Hobut, Crompton, MBS, IME, EFEN and Lumel families frame by frame, by window size and primary range.
3Confirm The Electrical SpecRatio, secondary current, accuracy class, burden and short time thermal rating are checked against what the application actually needs, not only against the old label.
4Match The MountingDIN rail, side base, busbar, panel or split core. The mechanical fit is where most substitutions fail.
5Quote And SampleA written quotation with the confirmed part, and samples on the popular frames before a production order.

FAQ
Questions Buyers Ask
What if I only have a photograph?
That is usually enough. The rating plate carries the ratio, class and burden, and the busbar window can be measured from the picture with a reference object.
Do you sell the brands in the cross reference library?
No. Those pages exist so you can identify the frame you already use; what we supply is the QIANWEI equivalent.
