What shows up at the pad
The ABB ACS550-PD-125A-4+C192 is not a bare ACS550 chassis module — it ships as a factory-built pump panel built around the ACS550 platform, listed in the ABB irrigation-drive family and wired for 480 V three-phase service. Supply side is 3-phase at 380 to 480 V AC; output is 3-phase to the motor. The supply window matches transformer secondaries commonly seen on irrigation services.
Cabinet contents and what the integrator sees
The enclosure is NEMA/UL 3R rated and listed as service-entrance rated, with the ABB Advanced Keypad mounted on the door. That combination means it can sit outdoors at the pump pad with the disconnect landed directly to the line side — no upstream disconnect cabinet needed. Front-of-door controls are 22 mm pilot devices: a 5k speed pot, a Hand/Off/Auto selector, and three pilot lights for drive ready, drive run, and drive fault. The HOA and the speed pot set day-to-day pump operation: manual run at the panel or auto run from a remote contact. Surge protection is fitted at the line side, a control power transformer with an extra 100 VA of capacity is included, and a condensation heater lives inside the cabinet. The heater is the giveaway that the panel is built to sit through cold, damp nights — without it the ACS550 control board would be the first thing to suffer condensation on a spring morning. Cabinet footprint is 49 in tall by 32.36 in wide by 22.88 in deep, with a unit weight of 330 lb. At that mass the panel is a two-person lift onto a wall bracket or pad, and the wall or pad must be rated for the load — not something to surface-mount on a wooden pump-house wall.
Sourcing and supply posture
ACS550-PD-125A-4+C192 carries the full ABB pump-panel option code — the +C192 suffix bundles the NEMA 3R enclosure, the HOA / speed-pot pilot devices, and the CPT / surge / heater set into a single orderable string. Specifying it that way keeps the BOM line to one part number instead of a kit.
