For a panel builder, that collapses to three numbers to lock down before the BOM freezes: 380 to 480 V input, 2.4 A output current, and R1 footprint. Anything else about the panel — breaker sizing, line reactor, EMC filter — is downstream of those three. ## Why the R1 frame matters R1 is the smallest chassis in the ACS355 series, so the cabinet cut-out, the heatsink clearance and the surrounding wiring duct all key off that frame size. Step up the current rating and the drive walks to R2, R3, etc. — which is why an order-code swap inside the same series is not a panel drop-in.","metaTitle":"ABB ACS355-03U-02A4-4 VFD, 480V, 0.75 kW / 2.4 A, R1","metaDescription":"ABB ACS355-03U-02A4-4 machinery drive on a 380 to 480 V three-phase supply, rated 2.4 A / 0.75 kW (1 HP) in an R1 frame.
