What the buyer is actually looking at
The ABB ACS880-01-156A-5+B056 is a wall- and cabinet-mount ACS880-series low-voltage drive, listed under the ACS880-01 frame family at 9.07 kg — the form-factor an integrator expects when sizing a panel cut-out and gland plate around an ACS880 line spare. Catalog placement is Drives / Motor Drives inside Motors & Motor Controls, which is the class the integrator selects from when the motor on the BOM is paired to a direct-to-line replacement in the same enclosure footprint.
Frame-class siblings worth knowing on the BOM line
The same ACS880-01 frame is populated by ACS880-01-052A-5, which carries the identical 9.07 kg mass — meaning a cabinet prepped for that rating will accept this drive on the same mounting pattern, with the motor and parameter block re-sized to the higher current code rather than re-cut into the panel.
What a service swap actually involves
At 9.07 kg the unit is a one-person lift into a cabinet, but the AC bus-bar landing and PE bond are the parts of the swap that decide whether the drive comes back up clean — the mass is incidental to the wirework, and the wirework is what the commissioning engineer verifies first. For a like-for-like swap inside the ACS880-01 frame, the panel cut-out, gland plate entries, and option-module slot pattern carry across from one current rating to the next; the commissioning pass is parameter download, motor ID run, and the safety-circuit re-check, not mechanical rework.
Lifecycle and sourcing posture
Lifecycle status is not stated in the source data, so production posture is left qualitative; ABB ACS880-01 frame units of this code are commonly procured to order against a BOM line through the authorized channel.
