ABB 3HAC046362-001 Fan Ax 2/3 Cooling Fan Cable Harness

ABB 3HAC046362-001 Fan Ax 2/3 Cooling Fan Cable Harness

3HAC046362-001 is the ABB cable harness that runs to the motor cooling fans on ABB robots. ABB lists it in its parts catalogue as the Fan ax 2/3 cable harness and records it as a component of the double fan unit set for the IRB 8700, kit 3HAC060886-001; the same article number is listed in ABB's IRB 6660 product manual, in section 2.3.10 Installation of cooling fan for motors (option), where a cooling fan is fitted to a motor axis. The harness carries its length on the label — the label reads Art. No. 3HAC046362-001-2.3M, and ABB's data sheet gives the net length as 2300 mm, so the length marking on the label is a direct check you can make before ordering. ABB publishes these motor cooling fan harnesses by axis combination, and more than one of them looks alike on the bench, so send us the article number and the length suffix from the label of the harness you are replacing together with the robot model, and we confirm the match before you order.

Specifications

ABB's fan option documentation states that the robot cooling fan cabling is supplied with the robot when the fan option is ordered, and that these cables are delivered pre-manufactured and ready to plug in. Send us the article number and the length suffix from the label of your original harness and the robot model, and we confirm the match before we quote.

Industrial Applications

• IRB 8700 robots running the double fan unit set 3HAC060886-001, where this harness is the wiring to the motor cooling fans.
• Robots fitted with the ABB motor cooling fan option, as described in the IRB 6660 product manual, where a fan is fitted to a motor axis and the cabling runs from the robot base to that fan.
• Replacement of a fan harness damaged by heat, oil, dust or a handling accident on a robot that works continuously with motor cooling fans.
• Repair of a cell where a fan has stopped and the drive or motor side reports an over-temperature condition, where the harness is checked first alongside the fan unit.
• Service stock for integrators and maintenance teams who keep one harness per robot family with the fan option fitted.

Design Purpose

• Carries power and signal from the robot base out to the motor cooling fans, so the motor keeps its designed thermal margin under continuous duty.
• Delivered as a finished assembly rather than loose wire, so it is fitted without field termination.
• The length is marked on the label (-2.3M), which lets the correct length be verified against the harness in the cell before the order is placed.
• Identified by axis combination, so a single robot type can carry more than one fan harness and each has its own article number.
• Supplied against a defined article number with a recorded country of origin and customs classification, which keeps the paperwork straightforward on an import.

Common Failure Modes

• One or both fans do not run after a repair or a cable replacement — check the connector seating and the harness for insulation damage along the flexing section near the robot base before condemning the fan unit.
• The drive or motor side reports over-temperature or overload warnings on a robot that should be fan cooled — the harness and its connectors are checked first, because a broken conductor and a failed fan produce the same symptom.
• Damage at the base plate or where the harness passes the connection plate 3HAC025778-001 — a harness that is broken at the plate does not seat, and the fault is often attributed to the fan instead.
• The wrong fan harness fitted for the robot's fan configuration — the ax 1/2 and the ax 2/3 harnesses are separate article numbers, and a harness that does not match the fan set leaves the motor without its cooling path.
• Cooling restored on one axis only — the fan sits on one motor axis, so the axis it is mounted on is checked against the harness article number and the robot configuration before a replacement is ordered.
