ACQ580-01-026A-4+B056: pump duty, enclosure and control checks
ABB ACQ580-01-026A-4+B056 is an ACQ580 drive configuration intended for water-process motor control. ABB identifies an 11 kW, 25 A nominal 400 V reference for this size and lists the B056 enclosed version as IP55 in its product declaration.
Technical data for identification
| Technical item | Verified value / selection note |
|---|---|
| Complete designation | ACQ580-01-026A-4+B056 |
| Application family | ABB ACQ580 water-industry drive |
| Nominal power reference | 11 kW at 400 V |
| Nominal current reference | 25 A in ABB representative product declaration |
| Supply class | Three-phase 380–480 V AC family |
| B056 option | IP55 enclosure option; confirm ordered assembly |
| Duty selection | Verify normal/heavy-duty current and ambient derating |
For a drive or softstarter, compare the motor nameplate, overload profile, upstream protection, cabling, heat rejection and stop category with the actual machine. The installation drawing and the fitted option codes govern the final selection.
Order-code and compatibility review
For ACQ580-01-026A-4+B056, Verify the exact B056 enclosure, local panel, network option, analog I/O, pressure or level feedback scaling, EMC requirements and upstream protection. Do not infer an installed communications adapter or pump application macro from the base drive code.
Before substituting ACQ580-01-026A-4+B056, compare the complete label with the engineering drawing, ABB configuration data, installed accessories and site approval record. A partial designation or a similar enclosure cannot establish interchangeability.
Verification checklist
- Match nameplate and order code.
- Check site electrical or process limits.
- Prove interfaces and protective response.
Where this configuration fits
ACQ580-01-026A-4+B056 should be assessed in the actual equipment arrangement. Review pump curve, static head, minimum flow, dry-run protection and control philosophy. The drive rating should be checked against motor current, start and stop behavior, any bypass arrangement and the site's expected operating envelope.
A request for ACQ580-01-026A-4+B056 should identify the host system, process or motor duty, available supply and the expected normal and fault behavior. This makes the selection review specific to the installed equipment.
