The order code itself is the engineering handle, naming the U1 enclosure and the 157 A current class on the 4 variant. ## Cabinet and handling envelope At 89.81 kgs the ACS550-U1-157A-4 is the heaviest chassis in the four-row peer set — well over double the 36.29 kgs / 34.02 kgs chassis mass of the 059A-4 and 072A-4 frames, and the 19.96 kgs of the 096A-4 sibling. That mass is what dictates two-person lift, cabinet reinforcement, and how the drive is staged onto a mounting plate during a swap.","metaTitle":"ABB ACS550-U1-157A-4 Low Voltage AC Drive, 89.81 kgs","metaDescription":"ABB ACS550-U1-157A-4 low-voltage AC drive, 89.81 kgs, in the Motor Drives line.
