Eaton C321MP1 – Frequently Asked Questions

1) Which Eaton mounting plate do I order for an IEC Size G starter versus a Size C contactor?
The frame size drives the part number on the Eaton Freedom mounting plate. C321MP1 covers IEC Size A-F contactors and D15 multipole relays, C321MP3 covers IEC Size A-F starters, C321MP2 covers IEC Size G-K Freedom starters, and C321MP4 covers IEC Size G-K starters. So a Size C contactor takes C321MP1 and a Size G starter takes C321MP2 or C321MP4. Ordering across the A-F / G-K split will not mount correctly.
2) Will the Eaton Freedom mounting plate fit D15 multipole relays?
Yes. The A-F size plate is made to accept all D15 multipole relays along with IEC style contactors, starters and overload relays. That is the C321MP1 version; the starter-specific plates are ordered separately.
3) Can I use one Eaton C321MP plate for a mix of contactors and starters?
No. Within the A-F range, the contactor and relay plate (C321MP1) and the starter plate (C321MP3) are separate part numbers. Order the plate that matches the device you are actually mounting rather than trying to cover both with one.
4) What is the Square D equivalent of the Eaton Freedom C321MP mounting plate?
There is no one-to-one Square D part, because the plate follows the device family it mounts. The Eaton C321MP is a Freedom series plate for Eaton IEC Size A-F and G-K starters, contactors and D15 multipole relays. On the Square D side, the AK5PA231 is a Linergy HK component mounting plate and the LAD31 is a TeSys Deca DIN-rail mounting plate - each matched to its own series. Order the plate that matches the contactor or starter already specified.
5) How much space does the Eaton Freedom mounting plate take up inside a control panel?
It measures 6.1 in wide by 8.8 in long/deep, and stands only .5 in high off the mounting surface. That half-inch profile is what lets it drop into a crowded enclosure without eating clearance around adjacent devices, but you still need a clear 6.1 x 8.8 in footprint on the subpanel.
6) Is the Eaton Freedom mounting plate listed for use in industrial control panel assemblies?
It is cUL Listed, which is what inspectors and panel shops look for when the assembly has to hold up in industrial motor control work. No other rating is carried on the plate itself.
7) Do I need this plate, or can I just mount an Eaton contactor straight to the subpanel?
The Freedom mounting plate is an accessory, not a required part of the contactor. Its use is giving panel builders one common, standardized surface to hang IEC style contactors, starters and overload relays on, and to keep hole patterns consistent across Size A-F or G-K devices. If you are drilling and tapping the subpanel for each device anyway, you do not need it; if you want a repeatable pattern for OEM builds or retrofits, you do.
8) What is the difference between the Eaton Freedom mounting plate and a DIN-rail mounting plate like the Square D LAD31?
The Eaton Freedom plate is a flat panel plate sized to the Freedom line and matched by IEC frame size, A-F or G-K. The Square D TeSys Deca LAD31 is a DIN-rail mounting plate built around the TeSys Deca line, so it is the choice when your devices are TeSys and your panel is rail-based. Square D also offers the Linergy HK component mounting plate, and ABB has a THQC 1-pole front mounting plate for THQC breakers. Plates are line-specific, so match the plate to the brand and series of the device you are mounting.
9) Can I use an ABB THQC front mounting plate in place of the Eaton C321MP?
They serve different devices. The ABB TQCFMP1 is a THQC series 1-pole front mounting plate, tied to that breaker line. The Eaton C321MP is a Freedom series plate for IEC style contactors, starters and overload relays across IEC Size A-F, and is cUL Listed. Substituting across the two will not give you the mounting pattern the Eaton motor control device expects.
