Multiquip Serial & Model Number Guide
Every Multiquip generator carries a model/serial label. Here is where to find it, what each part of the number means, and how to use it for parts, service and age.
Where to find it: the DCA nameplate on the unit. You need the FULL model number (every segment below) to find the correct manual or electrical schematic — Multiquip's own tech-support process is keyed to it.
What the number means
Worked example — DCA300SSJU4F2:
| Part | Meaning | Detail |
|---|---|---|
DCA | Product line | Diesel Coupling Alternator — Multiquip's own name for the line, per their official nomenclature bulletin. |
300 | Power rating | The kVA rated output. |
SS | Enclosure | SS = Super Silent (US = Ultra Silent instead). |
J | Engine manufacturer | C = Cummins, I = Isuzu, J = John Deere, K = Kubota or Komatsu, V = Volvo. |
U | Assembly location | U = assembled in the USA (no U = assembled in Japan). |
4F | Emissions tier | The digit is the engine emissions tier; F = Final (I = Interim instead). |
2 | Revision | Revision within the series (a C instead denotes white paint, CAN a Canadian-market model). |
Using the serial number
This full breakdown comes directly from Multiquip's own "DCA Model Numbers Nomenclature" technical bulletin — quote the complete model number, not just the DCA power rating, when ordering parts or manuals. No public serial-to-build-date formula was found.
