ABB ACH580-01-088A-4 HVAC AC Drive 45 kW 88 A

45 kW HVAC drive on frame R5

At 45 kW it opens frame R5, a size seen on central plant pumps and large fans. The catalogue type that matches is the ACH580-01-088A-4: three-phase, 45 kW typical motor power, 88 A nominal current, frame R5. 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.

ABB equips the ACH580 with building functions rather than generic machine macros, among them an energy optimiser with kWh counters, stall and overload protection, Drivetune smartphone commissioning with the Bluetooth panel and override (fire) mode. See more ratings under AC drives; the sister platform is described on the ABB ACS580 page.

Technical specifications

Sizing the ACH580-01-088A-4 against the motor

The catalogue gives three ratings for this type. Nominal use is 88 A for 45 kW. Light-duty use on 380 to 415 V is 82.7 A for 45 kW, which allows 110% overload for one minute in ten (about 91 A, derived). On a 440 to 480 V supply the light-duty current is 77 A, matching 60 hp. ABB states that all ACH580 ratings apply at +40 degrees C ambient.

Allow 203 mm of width and 295 mm of depth for the IP21 drive, plus a height of 732 mm with the gland box. The IP55 enclosure needs 203 mm by 320 mm and 732 mm in height and weighs 29 kg, against 28.3 kg for IP21. With a main switch or C1 filter variant the IP55 body becomes 1023 x 203 x 342 mm and 33 kg.

The catalogue’s SynRM selection guide matches this drive with 37 kW M3BL200MLB4 at 3000 rpm (84.6 A nominal, motor efficiency 94.8%, package efficiency 92.7%); 37 kW M3BL250SMF4 at 1500 rpm (82.0 A nominal, motor efficiency 95.2%, package efficiency 93.1%). Read the package efficiency as a calculated value for the drive and motor together, useful when comparing options but not a substitute for the motor’s own datasheet.

How the code is built

An order line starts with ACH580-01-088A-4: 01 marks the wall-mounted drive, 088A is the rating field and 4 the voltage class. Typical plus codes are +B056 for IP55, +F278 for a main disconnect switch with auxiliary contact, +F316 for the disconnect switch plus a C1 filter and +C135 for flange mounting.

BACnet MS/TP, Modbus RTU and N2 need no adapter. Other networks plug in as F-series adapters, such as DeviceNet via FDNA-01 (+K451), CANopen via FCAN-01 (+K457) and LonWorks via FLON-01 (+K452).

Standard equipment and limits listed by ABB: thermistor inputs for PTC and Pt100, Pt1000, KTY or Ni1000 sensors, an operating range of -15 to +50 degrees C, 5 to 95% relative humidity without condensation, altitude derating of 1% per 100 m between 1000 and 4000 m and coated circuit boards.

Documents and quotation

Figures come from the ABB drives for HVAC ACH580 series catalogue (3AUA0000186691, revision F, dated 9.14.2019), linked on this page. Seven Star LLC supplies the ACH580-01-088A-4 on request from Muscat; send the motor nameplate, supply voltage, enclosure class and building-network protocol with your RFQ, and the quotation states availability and lead time.

Confirm before ordering: the complete type code with plus options, motor current at your supply voltage, site temperature and altitude, and that this catalogue revision still matches ABB’s current listing for the type.
