What ships under this order code
The ABB ACS880-01-156A-5+D150+L503 is a wall-mount low-voltage AC drive from the ACS880-01 family, rated for a 3-phase 380-500 V input, ordered with the +D150 and +L503 factory option codes baked in. The drive is listed at 54.88 kg, the figure a panel builder uses for the lift-in plan and cabinet structural loading. The suffix string is the part most people miss on a second source request: +D150 and +L503 are factory-installed option codes on the base ACS880-01-156A-5, not field-installable add-ons, so any cross-reference has to honor the full order code.
Base frame vs configured frame
A drop-in retrofit from a panel specified around the base ACS880-01-156A-5 generally clears mechanically, but the +D150 and +L503 options change the I/O and fieldbus map, so the controller program and the terminal schedule need a review before commissioning, not a wiring re-pull.
Family context and what 156 A actually drives
The ACS580-01-180A-4 sits at 54.43 kg per the peer row, a different control firmware stack, so it is a substitution only at the spec stage, not a late-stage field swap.
Sourcing posture
A configured string like +D150+L503 is best sourced to order against the ABB ordering channel, with the full suffix string quoted on the line so the factory applies the option cards at build rather than a distributor trying to retrofit them at the bench. The base catalog code is a 156 A wall-mount unit at 54.88 kg; an RFQ carrying the full ACS880-01-156A-5+D150+L503 string is the cleanest way to lock the configuration before the BOM freeze.
