The ABB 3ABD00015749-S is the R3 frame for a drive rated 31 A at 380 V. IE2 efficiency class covers fixed-speed motor loads without premium-efficiency expectations.
Frame size and panel fit
The R3 frame is the mechanical envelope for the 31 A, 380 V variant. If you're swapping into an existing panel, verify the gland-plate cutout and DIN-rail or screw-mount pattern against the R3 footprint — the next frame up (R4) carries higher current and won't share the same hole centers.
