What lands on the panel
The ABB ACS880-01-034A-5+C135+P940 is the wall-mount ACS880-01 frame built around the 034A current rating, with the +C135 and +P940 option codes layered on at the factory. Input is 3-phase 380-500 V, so it drops onto the standard IEC low-voltage bus without a step-down transformer. Net weight on the bill of materials is 15.88 kgs — that's a one-person lift with a panel handle, not a forklift job, but the enclosure still wants to be sized for it and the lifting plan written around it. The +C135 and +P940 suffix is the part that needs a closer read before the BOM is frozen: those codes change the I/O, feedback, or option-card set on the base 034A-5, so the commissioning engineer should reconcile them against the wiring diagram and the option-card slot map before energising.
What the option string does to the base 034A-5
Strip the suffixes and you get ACS880-01-034A-5 at 10.43 kgs. The +C135+P940 build weighs 15.88 kgs — the mass delta reflects added option hardware inside the same enclosure, not a different frame. In other words: panel cutout, mounting footprint, and cooling airflow stay the same as the 034A-5, but the centre of gravity shifts and the shipping crate has to be rated for the heavier unit. If the panel was laid out for the base 034A-5, the +C135+P940 lands in the same hole — it's the wiring side and the option-card documentation that need reconciling, not the mechanical mounting.
Where it sits in the ACS880-01 5-series ladder
The neighbouring 5-series frames in the same voltage class are ACS880-01-040A-5 at 18.14 kgs and ACS880-01-065A-5 at 23.13 kgs — both heavier, both covering the next current step up. For the controls integrator, the practical read is: a panel designed for a 040A-5 has the thermal headroom and the gland-plate area to take this 034A option build without rework. A panel designed for the lighter base 034A-5 needs a weight and a centre-of-gravity check before the swap, and a wiring-diagram check after.
Sourcing posture
For an MRO planner holding a spare, the cleanest move is to confirm the exact option-string definition against the original purchase order before issuing an RFQ — the base 034A-5 is a valid mechanical and electrical alternative only if the panel design genuinely doesn't depend on what +C135 and +P940 bring to the I/O and option-card set.
