What the order code names
The ABB ACS510-01-04A1-4 is a wall-mount inverter drive in the ACS510 family, sized for 380 - 480 V three-phase supplies at 50 - 60 Hz. The "-04" frame rating and A1 terminal style with the -4 enclosure designation are how ABB distinguishes this build from higher-current siblings in the same series.
Rated 380 - 480 V at 50 - 60 Hz per the supply spec; panel spec should match the motor's rated voltage and frequency class. Within the ACS510 line, heavier siblings such as the 025A-4 at 11.2 Kg and the 072A-4 at 26.5 Kg sit above this frame in current rating.
Cabinet footprint and handling
Chassis dimensions of 40 cm x 24 cm x 48.5 cm with a wall-mount posture — leave panel depth and clearance for the cooling path on the heatsink side and the gland plate below the A1 terminals. At 8.2 Kg (9.5 Kg shipping weight), it is a one-person lift but the panel backplate still needs to be rated for the mass — not a shelf part.
Frame-2 swap question against the 09A4-4
Both the 04A1-4 and the 09A4-4 are frame-2 ACS510 units sharing the 8.2 Kg chassis mass and the same 380 - 480 V, 50 - 60 Hz supply class, so electrical fit at the bus and the motor leads is the same family.
Sourcing posture
Quoted lead time on this line is 1 - 10 working days, which is the window an MRO planner should use to schedule the swap and arrange the panel outage. Specifying this drive into a BOM or ordering against an existing line is the route to a firm quote — ABB-original material with the ACS510 series designation, no declared successor in this evidence set.
