The ABB ACS800-17-0170-5+C129 is the 170 A rating slot in the ACS800-17 cabinet-built low-voltage drive family, with the +C129 option suffix carried on the order code. The series sits in the Motor Drives class under Motors & Motor Controls, which is the slot a buyer cross-shopping regenerative or four-quadrant ACS800 variants lands in. What jumps out on the spec sheet for someone weighing the BOM line is the 521.63 kg figure — this is a freestanding cabinet, not a wall-mount inverter, so rigging and floor-loading decide the install plan before the electrical work does. The listing text reads ACS800-17-0170-5+C129 - DRIVE by ASEA BROWN BOVERI, which is the legacy brand string ABB carried before the ABB-only nomenclature; it is still the same manufacturer of record.
What the headline numbers drive
Packaged mass of 521.63 kg places the unit in the cabinet-class range; use fork pockets or a rated lifting beam and verify the receiving floor takes the point load without deflection.
Where the class is applied
ACS800-17 units are the cabinet-integrated, low-voltage industrial drives used for process-line motor control — pumps, fans, conveyors, mixers, and extruders where the line-side disconnect, contactor, and sometimes line filter are built into the same enclosure as the inverter. The +C129 suffix is an option-code addition to the base 170 A frame, so the cabinet you receive reflects both the frame rating and whatever option bundle C129 defines.
Sourcing posture
This is a configured ACS800-17 build rather than an off-the-shelf inverter, and the +C129 suffix means the supply line is order-specific — quoted against an RFQ, not pulled from a shelf. Send the BOM line with the option-code suffix and the cabinet rating you need validated, and the response carries the build configuration.
