ABB ACH580-01-145A-4 HVAC AC Drive 75 kW 145 A

Where the ACH580-01-145A-4 fits in a building

ACH580-01-145A-4 is a wall-mounted ABB ACH580 drive made for heating, ventilation and air conditioning. ABB’s catalogue rates it at 75 kW and 145 A in no-overload use on a 380 to 415 V network, and builds it on frame R6. Typical jobs are supply and extract fans, chilled-water and heating pumps, cooling-tower fans and similar variable-torque loads in commercial and industrial buildings. It is the only 75 kW rating and sole occupant of frame R6 in this table.

Among the HVAC features in the control program are real-time clock scheduling, PID controllers for process control, motor flying start and motor preheating. Related products are in AC drives and on the ABB ACS580 page.

Technical specifications

Reading the 145 A rating

Start from 138 A: this is the continuous light-duty current at 400 V, enough for a 75 kW fan or pump motor, with 110% for one minute (about 151.8 A, derived). If the motor is wound for 460 V or 480 V, read the 124 A, 100 hp column instead. The nominal 145 A figure is for loads without any overload demand.

Frame R6 in IP21 form stands 727 mm tall including the gland box (548 mm without it), 252 mm wide and 369 mm deep, and weighs 42.4 kg. The IP55 build measures 727 x 252 x 380 mm at 43 kg. The catalogue lists no switch or C1 variant for frames above R5.

ABB’s selection guide for IE4 synchronous reluctance motors names the ACH580-01-145A-4 as the matched drive for 55 kW M3BL225SMF4 at 3000 rpm (122 A nominal, motor efficiency 95.3%, package efficiency 92.6%); 55 kW M3BL250SMA4 at 1500 rpm (121 A nominal, motor efficiency 95.7%, package efficiency 93.1%). 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.

Options that change the order

An order line starts with ACH580-01-145A-4: 01 marks the wall-mounted drive, 145A is the rating field and 4 the voltage class. Typical plus codes are +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.

Add a fieldbus only when the building network needs one: PROFINET IO via FPNO-21 (+K492), EtherNet/IP via FEIP-21 (+K490) and PROFIBUS DP via FPBA-01 (+K454) are among the choices.

On board you get six digital inputs and two analog inputs, two analog outputs and three relay outputs, a 24 V DC auxiliary supply of 250 mA, thermistor inputs for PTC and Pt100, Pt1000, KTY or Ni1000 sensors and an operating range of -15 to +50 degrees C.
