3HAC025466-001 is a fan listed among the IRC5 controller spare parts. It supports the cooling arrangement of the applicable controller assembly. Match the complete part number and installed fan connection before replacement; the controller parts list alone does not establish the fan electrical ratings.
Use the complete -001 item reference when comparing the installed fan with the replacement. Check the mounting pattern and connector arrangement together. Housing dimensions alone do not establish electrical compatibility or identify all included harness and mounting parts.
Keep the controller ventilation path unobstructed and follow the applicable ABB maintenance instructions for ducts, fans and filters. IRC5 cooling options vary by cabinet configuration; do not transfer a cooling option or maintenance arrangement to another cabinet solely because the fan looks similar.
Controller-cabinet work requires qualified personnel and mains isolation in accordance with ABB instructions. Retain the documented mounting and lead routing, and check the fan installation before returning the cabinet to operation. No energized replacement procedure is asserted for this item.
Engineering check: Confirm 3HAC025466-001 is the IRC5 fan at the documented parts-list position. Match the connector keying, lead routing, mounting orientation and airflow arrow to the removed unit; keep wiring clear of the impeller.
Acceptance test: After installation, command the controller through a normal warm-up cycle. Verify immediate fan start, unobstructed airflow, no rubbing or abnormal vibration, and stable cabinet temperature without fan or thermal alarms.
