ABB ACH580-01-026A-4 HVAC AC Drive 11 kW 25 A

A 11 kW ACH580-01 for 400 V HVAC motors

At 11 kW it tops frame R2 and covers many mid-size pump sets. The catalogue type that matches is the ACH580-01-026A-4: three-phase, 11 kW typical motor power, 25 A nominal current, frame R2. It is the HVAC-optimised sibling of ABB’s general purpose drive and keeps the same all-compatible platform, so panels, PC tools and fieldbus adapters carry over.

Functions that building automation asks for come with the drive, for example belt-loss (under-load) detection, real-time clock scheduling, PID controllers for process control and motor flying start. Other sizes are listed in AC drives, and the related general-purpose family is on the ABB ACS580 drive page.

Technical specifications

Sizing the ACH580-01-026A-4 against the motor

The catalogue gives three ratings for this type. Nominal use is 25 A for 11 kW. Light-duty use on 380 to 415 V is 23.8 A for 11 kW, which allows 110% overload for one minute in ten (about 26.2 A, derived). On a 440 to 480 V supply the light-duty current is 23 A, matching 15 hp. ABB states that all ACH580 ratings apply at +40 degrees C ambient.

The catalogue dimension table lists 473 x 125 x 229 mm and 6.6 kg for IP21 frame R2 (the 432 mm height applies without the gland box). IP55 is 503 x 128 x 239 mm and 6.8 kg. With a main switch or C1 filter variant the IP55 body becomes 503 x 128 x 257 mm and 7.5 kg.

ABB’s selection guide for IE4 synchronous reluctance motors names the ACH580-01-026A-4 as the matched drive for 11 kW M3AL132SMC4 at 3000 rpm (25 A nominal, motor efficiency 92.6%, package efficiency 90.0%); 11 kW M3BL160MLA4 at 3000 rpm (25.0 A nominal, motor efficiency 92.6%, package efficiency 90.2%); 11 kW M3AL132SMC4 at 1500 rpm (24 A nominal, motor efficiency 93.3%, package efficiency 90.6%). Package values are calculated for the drive and motor together, so treat the table as a selection aid rather than a commitment for other motors.

How the code is built

Four fields make up ACH580-01-026A-4: the ACH580 series, 01 for wall mounting, 026A for the rating and 4 for the voltage range. Without plus codes you receive the IP21 drive with the assistant panel; options include +L512 for CHDI-01 with 115/230 V inputs, +B056 for IP55, +F278 for a main disconnect switch with auxiliary contact and +F316 for the disconnect switch plus a C1 filter.

Network options are ordered with +K codes. Examples from the table are LonWorks via FLON-01 (+K452), ControlNet via FCNA-01 (+K462) and EtherCAT via FECA-01 (+K469); the standard protocols stay available regardless.

On board you get 5 to 95% relative humidity without condensation, altitude derating of 1% per 100 m between 1000 and 4000 m, coated circuit boards, a DC choke built to IEC 61000-3-12 and Safe Torque Off certified to SIL 3 / PL e.

Applications in HVAC and building services

At this rating the ACH580-01-026A-4 is typically applied to larger air handling unit fans, chilled-water primary and secondary pumps, condenser-water pumps, cooling-tower fans and booster pump sets in commercial buildings, hospitals, hotels and district cooling plants. These are variable-torque loads, so energy use falls steeply as speed is reduced, and the built-in PID controllers let the drive hold a pressure or temperature set point directly from a transmitter signal. Real-time clock scheduling allows simple time-based operation where a full building management system is not used, and belt-loss detection warns of a slipping or broken belt on belt-driven fans.

Motor flying start is useful on fans that may already be turning when the drive starts, for example under the influence of wind or a neighbouring fan, because the drive can catch the spinning motor instead of tripping.

Selection and integration with the BMS

Select the drive from the motor nameplate current and the supply voltage, using the light-duty column for typical fan and pump service and the nominal column only where no overload is needed. If the motor is wound for the higher voltage range, read the corresponding column. Where the motor will be a new high-efficiency synchronous reluctance type, the SynRM pairing data on this page gives a starting point, with the motor datasheet as the final reference.

For building management integration, agree with the controls contractor which signals are exchanged over the network and which remain hardwired. The standard protocols remain available, and the network options listed above cover other systems. If a local isolator is required at the fan or pump, consider the main disconnect switch options listed in the ordering codes.

Installation practice in Oman and GCC plant rooms

Ambient temperature is the main concern in Omani plant rooms, particularly on rooftops and in poorly ventilated basements. The catalogue ratings apply at the stated ambient, so check the expected room temperature in summer and apply derating where needed. Choose IP55 when the drive is mounted near the equipment in a dusty or humid area, and IP21 for clean, ventilated electrical rooms. In coastal cities, keep the drive away from fresh-air intakes that bring in salt-laden air. Use shielded motor cable earthed correctly at both ends, separate control wiring from power cables, and keep the gland box fitted on the IP21 version for a tidy, inspectable installation.
