ABB ACH580-01-046A-4 HVAC AC Drive 22 kW 45 A

ACH580-01-046A-4: 45 A of fan and pump control for buildings

The 22 kW rating closes frame R3 and typically drives larger supply or extract fans. The catalogue type that matches is the ACH580-01-046A-4: three-phase, 22 kW typical motor power, 45 A nominal current, frame R3. 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.

Among the HVAC features in the control program are stall and overload protection, Drivetune smartphone commissioning with the Bluetooth panel, override (fire) mode and four start interlocks. Related products are in AC drives and on the ABB ACS580 page.

Technical specifications

Choosing between 400 V and 480 V data

Match the drive to the motor nameplate current. At 400 V the light-duty figure is 42.8 A (22 kW) and the nominal figure 45 A; the catalogue allows a 110% overload for one minute every ten minutes, roughly 47.1 A (derived from the 110% rule). Under a 480 V supply the table shows 44 A and 30 hp. The ratings are specified at +40 degrees C.

Frame R3 in IP21 form stands 490 mm tall including the gland box (490 mm without it), 203 mm wide and 229 mm deep, and weighs 11.8 kg. The IP55 build measures 490 x 206 x 237 mm at 13 kg. With a main switch or C1 filter variant the IP55 body becomes 733 x 207 x 258 mm and 15 kg.

ABB’s selection guide for IE4 synchronous reluctance motors names the ACH580-01-046A-4 as the matched drive for 18.5 kW M3BL160MLC4 at 3000 rpm (42.8 A nominal, motor efficiency 93.7%, package efficiency 91.4%); 18.5 kW M3BL180MLA4 at 1500 rpm (42.0 A nominal, motor efficiency 94.2%, package efficiency 92.0%). 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.

Decoding the ordering code

Four fields make up ACH580-01-046A-4: the ACH580 series, 01 for wall mounting, 046A for the rating and 4 for the voltage range. Without plus codes you receive the IP21 drive with the assistant panel; options include +L523 for CMOD-02 with an isolated PTC interface, +L512 for CHDI-01 with 115/230 V inputs, +B056 for IP55 and +F278 for a main disconnect switch with auxiliary contact.

Add a fieldbus only when the building network needs one: PROFIBUS DP via FPBA-01 (+K454), DeviceNet via FDNA-01 (+K451) and CANopen via FCAN-01 (+K457) are among the choices.

Standard equipment and limits listed by ABB: a 24 V DC auxiliary supply of 250 mA, 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 and altitude derating of 1% per 100 m between 1000 and 4000 m.
