Where This Product Is Used
The ABB ACS550-01-045A-4+B055 is a 22 kW (30 HP) general-purpose AC variable frequency drive engineered for demanding industrial and commercial environments. Engineers and system integrators specify this drive across a wide range of motor-control applications:
- HVAC Systems — Variable-speed control of supply/return air fans and chiller pumps in commercial buildings, data centers, and hospitals.
- Water & Wastewater — Centrifugal pump speed regulation for municipal water treatment plants, booster stations, and irrigation systems.
- Industrial Conveyors — Smooth start/stop and speed ramping for belt conveyors, roller tables, and material-handling lines.
- Compressors — Energy-efficient control of screw and reciprocating compressors in manufacturing and process industries.
- Mixers & Agitators — Precise torque control for chemical reactors, food-processing mixers, and wastewater aeration basins.
- Cooling Towers — Fan-speed modulation to maintain optimal thermal performance while reducing energy consumption.

Why Engineers Specify This Model
- Built-in EMC Filter (B055) — Eliminates the need for an external line filter, reducing panel footprint and wiring complexity. Meets EN 61800-3 Class C2 limits out of the box.
- Energy Savings — ABB’s Energy Optimizer function automatically adjusts magnetizing current to minimize losses at partial loads — critical for pump and fan applications running below full speed.
- Application Macros — Pre-configured parameter sets for HVAC, pump, fan, and general machinery reduce commissioning time from hours to minutes.
- Integrated PID Controller — Closed-loop process control (pressure, flow, temperature) without an external PLC for simple single-loop applications.
- Safe Torque Off (STO) — Meets IEC 61508 SIL 1 / EN 954-1 Cat. 3 for safety-critical stop functions without main contactor.
- Fieldbus Flexibility — Optional plug-in modules support PROFIBUS-DP, DeviceNet, CANopen, EtherNet/IP, and Modbus TCP for seamless integration into existing automation architectures.

Application-Specific FAQ
Q: Can the ACS550-01-045A-4+B055 control a 22 kW pump motor directly?
A: Yes. The drive is rated for 45 A continuous output at 400 V, which matches standard 22 kW 4-pole induction motors. Verify motor nameplate current does not exceed 45 A.
Q: Is an external EMC filter required?
A: No. The +B055 suffix denotes a factory-installed Class C2 EMC filter. This satisfies EN 61800-3 requirements for industrial environments without additional external filtering.
Q: What fieldbus protocols are supported?
A: Modbus RTU is built-in via the standard RS-485 port. Optional plug-in adapter modules add PROFIBUS-DP, DeviceNet, CANopen, EtherNet/IP, and Modbus TCP support.
Q: Can this drive be used in a HVAC BMS integration?
A: Yes. The integrated PID controller and Modbus RTU interface allow direct integration with BACnet gateways and most building management systems.
Q: What is the warranty period?
A: Konmask.com provides a 12-month warranty on all ABB drives against manufacturing defects. Extended warranty options are available — contact us for details.
