ABB ACH580-01-430A-4 HVAC AC Drive 250 kW 430 A

ACH580-01-430A-4: 430 A of fan and pump control for buildings

Building services engineers who need a 250 kW drive on a 400 V supply will find the ACH580-01-430A-4 in ABB’s ACH580 catalogue. The type delivers 430 A nominal output from a frame R9 housing and ships with the HVAC control program, an assistant control panel, a DC choke and Safe Torque Off. At 250 kW it is the largest wall-mounted ACH580-01 rating in the catalogue and the top of frame R9.

Software separates it from a general purpose drive: the HVAC program supplies belt-loss (under-load) detection, real-time clock scheduling, PID controllers for process control and motor flying start.

Technical specifications

Choosing between 400 V and 480 V data

Start from 400 A: this is the continuous light-duty current at 400 V, enough for a 200 kW fan or pump motor, with 110% for one minute (about 440 A, derived). If the motor is wound for 460 V or 480 V, read the 414 A, 350 hp column instead. The nominal 430 A figure is for loads without any overload demand.

Allow 380 mm of width and 418 mm of depth for the IP21 drive, plus a height of 955 mm with the gland box. The IP55 enclosure needs 380 mm by 477 mm and 955 mm in height and weighs 103 kg, against 97 kg for IP21. The catalogue lists no switch or C1 variant for frames above R5.

For energy-efficiency work, ABB’s IE4 SynRM motor table lists the ACH580-01-430A-4 alongside 200 kW M3BL315MLA4 at 1500 rpm (427 A nominal, motor efficiency 96.7%, package efficiency 94.5%). These numbers describe that specific pairing; ABB calculates them for the combined drive and motor, and other motor types need their own check.

How the code is built

Four fields make up ACH580-01-430A-4: the ACH580 series, 01 for wall mounting, 430A for the rating and 4 for the voltage range. Without plus codes you receive the IP21 drive with the assistant panel; options include +F278 for a main disconnect switch with auxiliary contact, +F316 for the disconnect switch plus a C1 filter, +C135 for flange mounting and +L501 for the CMOD-01 relay and 24 V module.

Add a fieldbus only when the building network needs one: EtherNet/IP via FEIP-21 (+K490), PROFIBUS DP via FPBA-01 (+K454) and DeviceNet via FDNA-01 (+K451) are among the choices.

Across the range ABB specifies 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, an operating range of -15 to +50 degrees C and 5 to 95% relative humidity without condensation.
