That model name is an IMS product code — series, cup count, height and hole pattern are all encoded in it. IMS basket codes, decoded explains how to read one, and lists every code covered here.
The shallowest of IMS’s 54mm competition baskets — 22mm, against 24mm for the standard 2-cup and 26/28mm for the taller variants. IMS rates it 12–14.5g for a dark roast, rising to 14–16g for a light one, which makes it the one to reach for if you pull lower doses than Breville’s stock 54mm baskets assume.
Geometry is the rest of the B62 family unchanged: a Ø62.5mm border, Ø54mm internal body, ridgeless, and 583 of IMS’s E-pattern holes at 0.30mm over a Ø44mm perforated area, for a Ø53/53.4mm tamper.
A practical note on picking a height in this family: the number that matters is the dose you actually pull, not the largest one the basket allows. A basket that is too deep for your dose leaves excess headroom under the shower screen; too shallow and you cannot fit the dose at all. At 22mm this is the low-dose choice — see the 24mm, 26mm and 28mm variants for higher doses.
IMS names Breville/Sage on this product page, and each cross-referenced machine below states a 54mm portafilter on its own manufacturer page.

Other items confirmed to fit machines this one fits — useful if you're kitting out a single setup. The count is how many of those machines overlap; nothing here is a new fitment claim.
