ABB 3AXD50000049451

ABB 3AXD50000049451 is a long-life axial cooling fan designed for ABB ACS880 R8/R9 IP55 drives. It is used as a replacement cooling component to maintain adequate airflow and thermal management inside the drive system. ABB-related product listings identify it as “FAN ACS880 R8/R9 IP55” and as a replacement fan kit/component.

Product Parameters

The published technical information specifies 24 V, 3.4 A and IP55; the source also notes that the current/power value on the fan label may represent a maximum value depending on the manufacturer. 

Core Function

The 3AXD50000049451 provides forced-air cooling for compatible ABB drives. Its main functions include:

• Removing heat generated by power electronics during operation.
• Maintaining airflow through the drive cooling path.
• Supporting stable operation of power components.
• Serving as a replacement for worn or failed cooling fans.
• Helping prevent excessive internal temperature caused by insufficient ventilation.

The part is specifically listed for ACS880 R8/R9 IP55 applications. 

Design Features

The fan uses an axial-flow design optimized for drive cooling applications. Its IP55 designation makes it suitable for the specified protected drive enclosure environment. ABB-related documentation also identifies 3AXD50000049451 as the long-life fan used in the ACS880 R9 main fan kit. 

An ABB product document for 3AXD50000025544 R9 Main Fan Kit states that the kit includes two 3AXD50000049451 long-life fans, together with a grill/steel plate kit and screws. 

Hardware Composition

The primary component is the 24 VDC axial cooling fan. Depending on the replacement configuration, associated mounting hardware or a grill/plate assembly may be supplied separately as part of a larger fan kit. The individual 3AXD50000049451 should therefore be distinguished from complete ABB fan-kit part numbers. 

Application Scenarios

Typical applications include:

• ABB ACS880 R8/R9 drive cooling
• ACS880-01 drive systems
• Compatible ACx580-01 R8/R9 applications
• Industrial motor drive cabinets
• Variable-frequency drive cooling systems
• Replacement maintenance for aging or failed drive fans

A recent industrial procurement document also lists 3AXD50000049451 specifically as an ABB ACS880 axial fan for LV variable-speed-drive cooling applications. 

Maintenance Points

When replacing this fan, verify:

1. The drive frame size and model are compatible with R8/R9 requirements.
2. The replacement part number is exactly 3AXD50000049451.
3. The fan's 24 VDC supply and electrical characteristics match the installed unit.
4. Airflow direction and mechanical mounting are correct.
5. Fan blades and ventilation paths are free from dust and obstruction.
6. Abnormal noise, vibration or reduced airflow is investigated promptly.

Because the cooling fan is directly involved in thermal management, replacement should be performed according to the applicable ABB drive maintenance procedures.

Comprehensive Evaluation

ABB 3AXD50000049451 is a dedicated long-life axial cooling fan for ABB ACS880 R8/R9 IP55 drive applications. Its key identification parameters are 24 VDC, 3.4 A, IP55, with an approximate net weight of 0.8 kg. It is particularly relevant for maintenance and replacement of cooling components in high-power ABB drive installations.
