These were Heinemann CF breakers, and 100A was a standard size, although only 60A was used in the PVGFP. The ones with studs were CDs. Back in the day the dealer source was Rainshadow Solar of (I think) Orcas Island, Washington. I don't have a source for them now.

Those part numbers indicate an item from between 2003 and 2008 from AEE. I don't remember what they are though, and do not see those items codes in any old AEE catalogs. Besides Schneider, Magnum also sold similar breakers in 70A and 100A I think. You could probably source them from a breaker distributor but at much higher cost.

    Hello, Mechanics~

    I sold this early GFI for PV arrays to a homeowner decades ago.
    Page 2-5 of the attachment mentions a custom enclosure from AEE
    Solar; AEE part number 53.0090 and breaker mounting plate 53-0094.
    I'm sure that's probably what I bought for mounting the GFP
    assembly. The breaker plate is pre punched to fit the mounting
    tabs on back of these CF style breakers. This may also be known as
    an E-series breaker.

    I suspect this box was a joint project involving Dave Katz & Robin
    Gudgel. Now I need to add a suitable single pole DC breaker but
    all I have found so far are those with terminal studs that poke
    out out the back of the breaker. Two different eBay vendors had a
    photo that looked right but the product they shipped had the
    studs. I'm sure the breaker is non-custom but I haven't found an
    easy source for quantity one.

    I think the breaker body is 1" wide. Ideal specs would be 100 amp
    rated, and any voltage rating above 50. 80 amp rating would
    probably also work. It's for a 24v battery off grid setup. If
    anyone has a part they could sell to me, please reply off-list
    with a description of the age & condition, & requested prepayment
    including slow boat shipping to the SLC region, Utah.

    OR: if anyone could suggest a vendor who's likely to have this,
    all suggestions would be welcomed. Thanks in advance; the Wrench
    List is the Bomb~
