I've gone through the usual sites and not found that much outside of stratospheric cost.
Is there a moderate cost two pole 240V DIN rail mountable GFCI, suitable for NEC 2020 installs powering an EV outlet?

GFL2B200102 is a 20A version with a 10ma Trip, but the GFCI versions cap out at 25A,
and the factory is no longer accepting orders regardless on that product. A similar variant
caps out at 16A for the 2020 NEC trip threshold.

 
I used to get feed thru SQ D breakers that could be panel mounted using an adapter.. But what is the application? Are you mounting in an enclosure and were I’ll it be inspected?
 
I don't understand. Why are you looking for a DIN rail product instead of using a typical GFCI breaker in the panel, or a spa panel in between?
 
You are conflating “Ground Fault” devices with being the same as “GFCI” devices, they are NOT the same. All GFCIs are GF devices, but not all GF devices are GFCI.

The term “GFCI” ONLY applies to Class A devices, meaning they must trip at 5mA (4-6 actually). The 10+ mA trip types would NOT meet the NEC requirement for GFCI protection. They would be “GFEP”, Ground Fault Equipment Protection, which does NOT satisfy the new requirements for GFCI in residential installations. Forget all of those cheap IEC devices, they do NOT qualify. Unfortunately, it appears that all of the search engines make this conflation mistake and will show you the IEC devices even though they are INCORRECTLY applying that terminology.

If you want a UL listed GFCI breaker for a residential EV, assuming 30A+, the only options are to find a way to put it in the existing panel, or add the “Spa Panel” option mentioned by Jaggedbean.

If you are an equipment manufacturer, making listed control panels, you could look buying an OEM breaker base and then using a standard plug-in GFCI breaker. These bases are basically the guts of a spa panel.

Yes mounting in an enclosure and being inspected both.
It's a custom industrial application.
The Square D QUO breaker series has panel mounting clips, but also DIN rail clips, but also is not available in GFCI AFIK.

I am talking about using standard QO breaker on a QO2MB mounting base. I don't know if they are rail mountable.

Looks like no DIN rail clips, which is too bad.
But it's a great product to know about, thank you. Much better than actual spa panel guts.

List price is $59 even without the breaker, which is a lot given the number I will need to install.
