The +J400 tail is the option string that distinguishes this build from a base ACS355-03U-03A3-4, so the buyer quoting a replacement must carry the suffix through verbatim — it is part of the part number, not an accessory code. Input class is 3~ 380-480 V, matching the description on record. A motor or feed outside this range requires a different -03U- voltage designator; this build is not rated for it. ## Where this class of drive lives The part is catalogued under Motors & Motor Controls, in the Drives / Motor Drives sub-tree, which is where a panel OEM looks for compact low-voltage VFDs destined for pump, fan, conveyor, and simple machine-tool spindle duty. The ACS355 line in particular is positioned for serial-modbus and basic PID-style control loops where a full machinery drive would be overspec. ## Sibling cross-reference class The ACS310-03U-02A6-4 sits in the same 1.36 kg chassis as the ACS355-03U-03A3-4+J400, making it a cross-shop candidate when the ACS355 option code is unavailable. The 02A6 current rating is a different size point from the 03A3, and the ACS355 +J400 option set does not carry across to the ACS310 family. The ACS310-03U-06A2-4 carries the same 1.36 kg chassis at a higher current step, useful when the load was underrated on the original 03A3 build. It remains in the ACS310 family, not the ACS355 +J400 build, so the option code does not carry across.","metaTitle":"ABB ACS355-03U-03A3-4+J400 drive, 3~ 380-480V","metaDescription":"ABB ACS355-03U-03A3-4+J400 motor drive, 3~ 380-480 V input class, 1.36 kg chassis.
