Product Overview
The ABB WS FAN 230 68442966 Fan Kit for ACS800 is a cooling assembly used with compatible ABB ACS800 drive equipment. It supports forced-air cooling inside the drive enclosure, where power semiconductors, DC-link components, control electronics, and other heat-generating parts operate under load.
In an operating ACS800 cabinet, the cooling fan has a direct relationship with drive temperature. During continuous motor operation, high-load conditions, or installations with limited natural airflow, a properly functioning fan helps move heated air away from internal components and maintain the required thermal conditions.
The 68442966 fan kit is a service component rather than a control or power-conversion module. When replacing it, technicians should consider the fan assembly itself, its electrical connection, airflow path, filters, cabinet ventilation, and the drive’s temperature monitoring together.

Product Features
- Fan kit for compatible ABB ACS800 drive systems.
- Supports forced-air circulation through the drive cooling path.
- Helps remove heat generated during drive operation.
- Suitable for service replacement of the cooling assembly.
- Supports thermal management of high-power drive hardware.
- Intended for integration with the existing ACS800 cooling arrangement.
Working Principle
The fan assembly creates forced airflow through the drive’s designated cooling path. As the ACS800 operates, heat generated by the power stage and other internal components is transferred to the surrounding airflow and carried toward the appropriate ventilation outlet.
The fan’s effectiveness depends on more than motor operation alone. Blocked air passages, contaminated filters, incorrect installation, or restricted cabinet ventilation can reduce cooling performance even when the fan is rotating.
A fan-related fault may appear as a drive overtemperature warning or trip, increased cabinet temperature, abnormal fan noise, or reduced airflow. For this reason, service checks should compare fan operation with the complete airflow path rather than treating the fan as an isolated component.
Role in an ACS800 Drive Control Architecture
| System Element | Function |
|---|---|
| ACS800 Drive | Controls motor voltage, frequency, and operating conditions |
| 68442966 Fan Kit | Generates forced airflow for drive cooling |
| Power Semiconductor Stage | Converts electrical power and generates significant operating heat |
| DC-Link Components | Store and condition electrical energy within the drive |
| Temperature Monitoring | Detects thermal conditions and supports protective drive functions |
| Cabinet Ventilation | Supplies and removes air required by the drive cooling system |
| Motor | Receives the controlled electrical output from the drive |
The 68442966 Fan Kit supports the thermal side of the ACS800 architecture. Its condition can directly influence the operating temperature of the power stage and other heat-generating components.
Industrial Applications
| Application | Typical Use |
|---|---|
| Motor Drive Systems | Cooling ACS800 drives during continuous motor operation |
| Industrial Machinery | Thermal management for drives used in automated production equipment |
| Pumps and Fans | Maintaining drive cooling during extended variable-speed operation |
| Material Handling | Supporting drive operation in conveyors and lifting-related equipment |
| Process Equipment | Cooling drives operating under sustained load |
| Drive Maintenance | Replacement of worn or failed cooling fan assemblies |
Installation and Maintenance
- Verify the complete part number and confirm that the WS FAN 230 68442966 is suitable for the specific ACS800 drive configuration.
- Disconnect and isolate the drive according to the applicable electrical safety procedure before accessing the cooling assembly.
- Allow sufficient discharge time for the drive’s internal energy-storage components before opening the equipment.
- Record the existing fan wiring and connector position before removing the original assembly.
- Inspect the fan connector and wiring for loose contacts, damaged insulation, discoloration, or overheating.
- Check the airflow path and remove accumulated dust or debris from accessible ventilation areas before installing the replacement.
- Inspect filters and ventilation openings because restricted airflow can reduce cooling performance and shorten fan service life.
- Check the fan mounting arrangement and make sure the replacement assembly is securely positioned without mechanical interference.
- Inspect nearby cooling components for contamination or obstruction that could prevent the new fan from moving the required air.
- Restore the electrical connection carefully and verify that the fan wiring is routed away from moving or hot components.
- Run a controlled drive test after installation and check fan operation, airflow, drive temperature, and any active thermal warnings.
- Monitor the drive after returning it to service to confirm that temperature behavior remains within the expected operating condition under representative load.

Technical FAQs
What is the ABB WS FAN 230 68442966 used for?
The WS FAN 230 68442966 is a fan kit for compatible ACS800 drives. It generates forced airflow through the drive’s cooling path to help control the temperature of heat-generating internal components.
What symptoms can indicate a failing ACS800 cooling fan?
Typical indications can include abnormal fan noise, reduced airflow, fan-related alarms, rising internal temperature, or drive overtemperature faults. Restricted filters and ventilation paths can create similar symptoms and should also be checked.
Can a dirty air path cause the same problem as a failed fan?
Yes. Dust accumulation, blocked ventilation openings, or a contaminated filter can significantly reduce airflow even when the fan motor is operating. The complete cooling path should be inspected before replacing the fan assembly.
What should be checked after installing the 68442966 fan kit?
Verify the electrical connection, fan rotation or operation, airflow, mounting, and surrounding ventilation path. The ACS800 should then be operated under controlled conditions while monitoring temperature and any thermal warnings.
