It is listed at 31.75 kg, the figure that drives panel-cut planning and the two-person lift call-out rather than any electrical fit decision. ## Where this class gets used Motor Drives in this catalog tier are specified to vary AC induction motor speed and torque on industrial machinery — pumps, fans, conveyors, mixers — where the drive sits between the supply and the motor and handles the soft-start, ramp, and protection profile. ## Same-frame alternates to weigh The ACS550-U1-072A-4+B055+L512 is the closest same-frame alternate at 34.02 kg, with the +L512 suffix swap for +K466 as the engineering check before any drop-in call. The ACS550-U1-059A-4+B055 is the next-down current frame in the same +B055 option family at 36.29 kg, and the ACS550-U1-096A-4 is the next-up current frame without the +B055 suffix at 19.96 kg — neither is a like-for-like swap for this order code, so treat them as frame neighbours rather than substitutes. ## Sourcing posture","metaTitle":"ABB ACS550-U1-072A-4+B055+K466 Drive, 31.75 kg","metaDescription":"ABB ACS550-U1-072A-4+B055+K466 ACS550-series motor drive, 31.75 kg.
