We’ve supplied aluminum track rail to European and Indian wholesalers for over a decade. Three models take most of our repeated bulk orders: 6301 3-wire track rail, plus 6401 and 6404 four-wire track rail.

Many overseas buyers reach out to us confused about these three items. They see 6401 and 6404 look similar at first sight, and can’t figure out when to pick 6301 instead of four-wire types. We sort out real production details, cross-section specs and long-term client order feedback to give clear selection advice.

1. Internal Structure & Exact Size From Factory Drawings

All three extrusions use 6063-T5 aluminum, with 0.7mm base wall thickness and built-in reinforcing ribs. Copper bars are locked with special plastic clips, no shifting during long sea shipment.

Model 6301 – 3-Wire Single Circuit Track Rail

Three copper bars inside, including live, neutral and ground wire. It runs on one single circuit, simple and cost-effective. Outer width 34mm, total height 17mm. The ground wire meets EU and Australian safety standards, so it’s widely ordered by Indian and UK clients for home decoration and small retail shops. It works with all standard GU10 track spotlights, no extra complicated control parts needed.

Model 6401 & 6404 – 4-Wire Dual Circuit Track Rail

6401 and 6404 share the exact same internal layout and outer dimension. Four copper bars split into two independent power groups: L1+N as one circuit, L2+L3 as another separate control group. Official drawing size: outer width 32mm, full height 36mm, double-layer copper bar layout. This dual-circuit design is the biggest selling point for German, Dutch and Polish high-end store projects. Shop owners can separate spotlights into two lighting groups to adjust display brightness separately. Thick copper strips keep power stable even for 30-meter long track installation, no voltage drop or flickering lights.

The only small difference between 6401 and 6404 is partial outer slot design to fit different local power feed connectors, while circuit and load capacity stay fully consistent.
