Description:
The ABB 3AXD50000010152 is an Inverter R9 Row Cable Package / power interconnect cable harness assembly designed for ABB ACS6000 (and certain ACS5000) medium-voltage drive inverter sections. It comprises the pre-formed flexible copper straps or laminated bus bar jumpers with silver/tin-plated crimp lugs that link the R9-indexed power semiconductor modules (IGCTs or high-power IGBTs) within a single inverter phase leg or across the “row” of series-connected cells, ensuring correct current distribution, minimal stray inductance, and mechanical compliance for thermal expansion in the high-current DC-link to AC-output path.
Application Scenarios:
A metals rolling mill running a 12-pulse ABB ACS6000 SD drive for its 7 MW main stand motor noticed abnormal heating on the lower-phase-link straps of Inverter Section A during a thermal imaging patrol. Closer inspection revealed one of the original flexible copper jumpers had work-hardened and cracked near the crimp after 14 years of thermal cycling, increasing resistance and hot-spot temperature by ~25 °C. Rather than fabricate a custom jumper (which risks incorrect cross-section or poor crimp), the electrical crew ordered the official ABB 3AXD50000010152 R9 Row Cable Package for that inverter row. They isolated the drive, removed the top and bottom DC-link/disconnect isolators per LOTO, unbolted the degraded straps, installed the new pre-shaped links from the package using new factory-supplied hardware and the specified torque values, and reapplied power. Post-run infrared check showed uniform temperature across all row connections within 3 °C. This case illustrates why the 3AXD50000010152 matters: it is not a generic cable but a dimensionally and electrically matched interconnect set — using the wrong homemade link can introduce stray inductance that stresses the semiconductors or creates local hot spots that precipitate failure.

Technical Principles and Innovative Values:
- Innovation Point 1 — Optimized Stray Inductance via Matched Geometry. The ABB 3AXD50000010152 straps are pre-formed to the exact bend radius and spacing specified in the inverter’s EMC/stray-inductance budget. This minimizes di/dt voltage overshoot during IGBT/IGCT turn-off — a critical factor in preventing false dv/dt stress on the power semiconductors that a randomly fabricated jumper cannot guarantee.
- Innovation Point 2 — Silver-Plated Contact Surfaces & Controlled Crimp Quality. All load-bearing contact faces are silver-plated (or tin-plated per design rev) and the crimps are produced on calibrated hydraulic tooling to ABB’s pull-test standard. This ensures micro-ohm contact resistance and long-term stability under hundreds of thermal cycles — far exceeding field-made alternatives.
- Innovation Point 3 — Complete Kit with Torque-Certified Hardware. Unlike loose straps, the 3AXD50000010152 ships with the correct grade-8.8 / A4 stainless bolts, spring washers, and plain washers sized to the original M12/M16 holes, plus reference to the official torque value (typically 35–70 N·m depending on bolt size). Including the correct hardware removes guesswork and prevents under/over-tightening — a leading cause of connection overheating in MV drive rows.
