ABB 3HAC026525-001 Cooling Fan for DSQC639 Cabinet

Controller Cooling Fan for ABB IRC5 Computer Cabinet

Specifications

Industrial Applications

• Used in ABB IRC5P, IRC5C Compact and IRB 14000 (YuMi) robot controllers to cool the DSQC639 main-computer cabinet.
• Keeps controller electronics within safe temperature limits in automotive welding, material handling, machine tending and electronics-assembly cells.
• Prevents controller overheating that can trigger thermal shutdown or shorten component life.
• Routine preventive-maintenance replacement for aging or noisy fans in IRC5 control cabinets.

Design Purpose

The DSQC639 main computer runs the controller's core processing and runs hot during continuous operation. ABB fits a dedicated cooling fan to the computer cabinet so a steady airflow carries heat away from the electronics, keeping the main computer within its operating-temperature window instead of relying on the cabinet's ambient cooling alone.

Because the fan is a defined spare for a specific cabinet (DSQC639, 3HAC025527-001) across several IRC5 variants, fitment depends on the controller model — IRC5P, IRC5C Compact and IRB 14000 use this fan, while other IRC5 cabinet layouts may use a different fan. It is therefore a confirmed-fitment spare verified against the controller model, not a universal controller fan.

Common Failure Modes

• Bearing noise or grinding from age and dust accumulation.
• Reduced or zero airflow from a stalled or seized motor.
• Controller overheating or thermal shutdown caused by fan failure.
• Connector or wiring damage during cabinet service.
• Vibration-induced loosening of the fan mounting.
• Contamination (coolant mist, oil, dust) shortening fan life in harsh cells.
