Robot downtime is rarely caused by “mysterious software.” More often, it’s something brutally physical: a cable that has spent years being flexed, pulled, vibrated, and cooked by cabinet heat. When a power/control cable starts to fail, the symptoms can look random—unexpected stops, intermittent faults, or axis-enable problems that disappear the moment you open the cabinet door and wiggle the harness. That’s why OEM-identified cables matter.
ABB 3HAC026787-002 is listed by ABB with the straightforward description “Control cable power 15m.” In the spare-parts market, it is consistently presented as a 15-meter robot control/power cable, and at least one major MRO reseller describes it specifically as a robot control cable with a 15 m length and 1x male / 1x female connection.
What this part is best used for is equally straightforward: restoring correct cable length, connectors, and fit in ABB robot installations where cable performance is part of system reliability—not an afterthought.
Product Identification (What You Are Actually Buying)
Because “3HAC…” part numbers are frequently used across ABB robotics spares, procurement accuracy matters. The safest way to purchase is to anchor on the ABB part number and the ABB description, then confirm connector gender and cable length before shipping.
| Field | Specification / Market-Observed Detail |
|---|---|
| Manufacturer | ABB |
| ABB part number | 3HAC026787-002 |
| ABB description | Control cable power 15m |
| Cable length | 15 m |
| Connector statement (as listed by a reseller) | 1x male / 1x female connection |
| Common channel category | Robot cable & accessories / robot control cable |
| Typical controller context in listings | “IRC5 controllers” appears in third-party listings |
| Weight (reseller listing) | 45.28 lbs shown on one reseller page (often a shipping/handling weight; verify for logistics) |
Note on specifications: ABB’s public product page snippet is minimal (name + description). For electrical ratings (voltage/current), insulation class, conductor size, or connector part series, you normally confirm via the robot’s spare-parts manual, the controller wiring documentation, or the labeling on the existing cable you are replacing.
What “Control Cable Power” Implies in Real Applications
The phrase “control cable power” is not just marketing. It implies a cable intended to carry power-related connections within a robot control ecosystem, where reliability is influenced by:
-
Mechanical durability (routing, bend radius, vibration)
-
Connector integrity (locking, contact wear, contamination)
-
Electrical stability (consistent contact resistance, proper grounding path where applicable)
Third-party listings commonly label this part as an ABB robot power/control cable and associate it with ABB robot systems and IRC5 controller environments. Even if you treat those listings as “context, not gospel,” the consistency across channels supports the practical view: this is a robot-system cable, not a generic industrial extension lead.
Where This Cable Fits Best
Most users buy a part like 3HAC026787-002 for one of three reasons:
-
Corrective replacement
A known cable fault exists (damage, intermittent stops, visible jacket wear, connector damage). Replacement with the correct ABB-referenced cable restores baseline system behavior. -
Preventive maintenance on high-cycle cells
In high-throughput robot cells, cable wear is a function of cycles and routing geometry. Swapping a stressed cable before failure can be cheaper than losing a production shift. -
Standardization of spares
Plants with multiple ABB robots often keep standard-length OEM-referenced cables to reduce mean time to repair. Since this part is explicitly a 15 m cable, it is easy to stock as a known length.
Buying and Inspection Checklist (Avoid “Looks Right” Mistakes)
Cables are a classic trap for purchasing teams because many problems only show up after installation. Use the checklist below to reduce returns and commissioning risk.
| Step | What to Check | Why It Matters |
|---|---|---|
| 1 | Part number matches exactly: 3HAC026787-002 | Prevents “close variant” substitution |
| 2 | ABB description aligns: Control cable power 15m | Confirms you are not buying a signal cable or different harness type |
| 3 | Length confirmed as 15 m | Routing slack and strain relief depend on length |
| 4 | Connector gender matches (1x male / 1x female per reseller listing) | Avoids “can’t mate to existing hardware” failure |
| 5 | Condition declared and understood (new/used/refurb) | Used cables can be fine, but lifespan is unknown |
| 6 | Visual inspection on arrival | Cuts, crushing, tight bends, oil ingress, connector pin damage |
| 7 | Basic electrical checks (as permitted by your maintenance SOP) | Continuity/contact issues are common early-failure causes |
A practical note: one large reseller explicitly states it is not an authorized distributor (common in the MRO world) and offers its own warranty terms. If your customer is strict about channel authorization, confirm sourcing rules up front.
Installation Notes That Improve Reliability
This section is intentionally “field boring,” because boring is what you want from power/control cabling.
-
Route for motion discipline: avoid sharp edges, avoid pinch points, and keep a consistent bend radius.
-
Do not use the connector backshell as a handle: pulling on connectors damages contacts and strain relief.
-
Secure the cable where it is meant to be fixed: uncontrolled movement leads to fretting corrosion at connectors and jacket wear.
-
Document the swap: record the part number, date, and reason for replacement. Cable history is useful when diagnosing recurring faults.
If you’re replacing a cable after intermittent faults, don’t throw the old one away immediately—label it and keep it long enough to confirm the fault is truly gone after several production cycles. That’s not superstition; it’s basic causality testing.
Summary
ABB 3HAC026787-002 is an ABB-identified spare part described as a “Control cable power 15m,” making it a clear fit for ABB robot installations requiring a 15-meter power/control cable with correct system-compatible fit. Market listings consistently reinforce the same identity and add practical details such as robot control cable, 15 m length, and 1x male / 1x female connection.
