ABB 3HAC027104-001 is an ABB Robotics spare part described as a “Process Cable Package 1-3 MH.” ABB product documentation for this part explicitly links it to the IRB 6660 robot family, with technical information noted for IRB6660 130 kg / 3.1 m variants and category placement under Base and Frame Harness.
In a high-payload robot cell, cables are not passive accessories. They are moving mechanical elements that must carry signals and sometimes auxiliary power while surviving constant motion, vibration, abrasion risk, and electrical noise. A “process cable package” is typically part of the robot’s process interface and dress-pack architecture: it provides the structured path for process-related connections between the robot base/frame harness area and the external tooling environment. When this component is healthy and correctly routed, it disappears into the background. When it begins to fail, it produces the most expensive kind of downtime: intermittent faults that depend on axis position, acceleration, and environmental conditions.
The name “1-3 MH” strongly implies a defined length class used by ABB for this package. ABB’s document also includes physical and logistics data that is valuable for spares planning, shipping, and warehouse control: it lists product net weight 7 kg, gross weight 7 kg, and key dimensions such as net length/depth 2000 mm, height 100 mm, and width 115 mm.

What This Process Cable Package Does in Practical Terms
On an IRB 6660-class robot, the “base and frame” area is where routing discipline matters most. This region sees high mechanical stress from repeated axis movements, and it is typically where cables transition between protected internal routing and external dress-pack or cell routing hardware. ABB’s categorization of this part under Base and Frame Harness indicates that 3HAC027104-001 is designed to integrate into that controlled routing architecture rather than being a generic stand-alone cable.
In most robot cells, a process cable package supports at least three operational goals:
-
Repeatable motion without cable interference
A defined cable package helps keep bend radius controlled and prevents the harness from becoming a “soft collision object” that can snag, rub, or fatigue early. -
Stable signal transmission in a noisy electrical environment
Robots operate next to servo drives, switching contactors, welding equipment, and VFD-driven peripherals. A purpose-built cable package reduces the probability of noise-induced process faults and intermittent tool feedback issues. -
Serviceability and fast restoration
A known ABB part number allows maintenance teams to replace a worn harness assembly quickly and restore the intended routing and connectorization instead of rebuilding a custom harness under time pressure.
Dimensions, Weight, and Trade Classification
ABB’s product document provides the kind of data that procurement and logistics teams care about (and that technicians appreciate when planning onsite replacement work).
| Parameter | ABB Published Value |
|---|---|
| Product Net Weight | 7 kg |
| Gross Weight | 8.5 kg |
| Product Net Length / Depth | 2000 mm |
| Product Net Height | 100 mm |
| Product Net Width | 115 mm |
| Customs Tariff Number | 85444290 |
| Country or Territory of Origin | Sweden |
That tariff classification and declared origin are frequently used in real-world import/export documentation, especially when robotics spares are shipped cross-border under urgent downtime conditions.
Stocking and Service Context
ABB’s document also lists stocking locations (warehouses) and references multiple geographic points, including Menden, Germany and Shanghai, China as stocked-at locations. This is operationally important because cable packages are often treated as “critical spares” for large robot cells: lead time and regional availability can determine whether downtime is measured in hours or days.
Additionally, the same ABB document places this item within the Robotics service structure as a spare part for IRB 6660 variants.
Installation Considerations for IRB 6660 Cells
Because this part is associated with base/frame harnessing on a large articulated robot, installation quality matters as much as the part itself. The most common failure causes in high-duty robot environments are mechanical:
| Risk Area | What Goes Wrong | Practical Prevention |
|---|---|---|
| Tight clamp points | Cable becomes a hinge and fatigues near the clamp | Use proper strain relief and allow controlled motion |
| Sharp edges or rubbing | Jacket wear leads to shield/conductor damage | Route through intended guides and protect at contact points |
| Incorrect bend radius | Internal conductor break over time | Keep bends gradual, especially near transition points |
| Re-routing near power lines | Noise couples into sensitive process signals | Maintain separation from motor/power cables where feasible |
After replacement, a disciplined test routine should include slow jogging through extreme positions first, then full-speed cycles under normal payload and process conditions. This helps reveal tension points and routing errors before production is resumed.
Purchasing Notes and Authenticity Control
For 3HAC027104-001, the “safe” procurement approach is straightforward:
-
Match the full ABB part number exactly: 3HAC027104-001
-
Confirm the ABB catalog description: Process Cable Package 1-3 MH
-
Confirm intended robot family use: IRB 6660 base/frame harness context
-
Verify shipping weight expectations around 7 kg for planning and receiving checks
Cable packages are easy to mis-source because many sellers describe them vaguely as “robot cable” or “body cable.” The ABB product document is your anchor: it ties this part number to IRB 6660 variants and provides traceable logistics data.
Summary
ABB 3HAC027104-001 is an ABB Robotics Process Cable Package 1-3 MH used in the IRB 6660 robot family, categorized under Base and Frame Harness and explicitly referenced for IRB6660 130 kg / 3.1 m technical context. With a listed net weight of 7 kg, defined dimensions, and a published customs tariff number 85444290, it is a practical, service-oriented spare part that supports reliable process connectivity in heavy-duty robotic production environments.
