It sits on the Motor Drives line under the ABB ACS355 family, the compact drives typically specified for fractional-kilowatt pumps, fans, conveyors and small machinery where panel space is tight. The listed supply class is 3~380-480 V per the order code. Fit depends on the panel's three-phase supply matching that input class; the ACS355-03U-02A4-4+K452 is not specified outside that range. Mounted mass is listed at 1.36 kgs, which keeps it on a standard wall or DIN-rail panel layout without special handling — one tech lifts it, and the panel does not need to be reinforced. ## Class context ACS355-class drives are general-purpose variable-frequency drives aimed at OEM machine builders and panel shops running light industrial loads — pumps, fans, mixers, small conveyors and packaging machinery. The K452 option suffix on this order code is the buyer-side signal that a factory-fitted option is bundled on the drive itself, so the BOM line stays a single part number rather than separate drive plus add-on. ## Cross-shop against the ACS310 The closest same-function sibling on file is the ABB ACS310-03U-02A6-4 at 1.36 kgs. The ACS310 line targets pump and fan loads with dedicated firmware, so cross-shopping weighs ACS355 general-purpose use against ACS310 pump/fan specialisation. Other ACS310 entries shift current rating or input class, moving them out of the same envelope.","metaTitle":"ABB ACS355-03U-02A4-4+K452 drive, 3~380-480V","metaDescription":"ABB ACS355-03U-02A4-4+K452 motor drive, three-phase 380-480 V input, listed at 1.36 kgs.
