POWER SYSTEMS / DATA CENTER BUSWAY
Overhead copper your electricians tap in minutes.
VoltFab builds data center busway as a system: open-channel track busway rated 160–800A, UL 857 listed to 600V and IEC 61439-6 type-tested, feeding tool-free tap-off boxes from 80–400A — every box 100% pre-tested before it leaves the factory.
SPEC SHEET
| Ratings | 160 / 250 / 400 / 630 / 800A |
|---|---|
| Voltage | 600V · UL 857 listed · 1φ/3φ |
| Standard | IEC 61439-6 type-tested |
| Tap-offs | 80 – 400A · tool-free plug-in |
| Conductor | Copper U-bar, open channel |
| Protection | IP2X finger-safe shrouds |
| QA | 100% factory pre-test on tap-offs |
OPEN CHANNEL VS CABLE TRAY
Add a rack without a rewiring project.
Cable-and-tray drops turn every rack addition into an electrician-sized event: de-energize, pull, land, label, inspect. An open-channel track busway runs overhead once, then tap-off boxes plug in anywhere along the run — tool-free, while the system stays live — turning a change that took a shift into minutes per rack. When a hall's intake outgrows the 800A track class, the same copper geometry continues as feeder busway rated to 6300A.
SYSTEM RANGE
Run, tap, meter — specified per section.
A busway order is a layout, not a line item: run lengths, tap positions and joint sets come from your rack elevation, then every section is built and verified against the type-test file.
| Section | Range | Notes |
|---|---|---|
| Track straight sections | 160 / 250 / 400 / 630 / 800A | Open channel, copper U-bar conductor |
| Feeder sections | 1600A and beyond, to 6300A | Feeding duty from service to distribution |
| Tap-off boxes | 80 – 400A | IEC / ETL to UL 857, tool-free plug-in |
| Tap metering | Per-tap current monitoring | Comms output feeds DCIM platforms |
| Voltage class | 600V, single- and three-phase | UL 857 listed for North American runs |
| Type tests | IEC 61439-6 verified | Temperature-rise and short-circuit evidence |
| Protection | IP2X finger-safe | Shrouded conductor channels throughout |
| Mounting | Threaded rod / trapeze sets | Modular joint hardware, torque-logged |
| Accessories | End feeds, telescoping joints | Blind ends and firestop-ready penetrations |
| Factory QA | 100% tap-off box pre-test | Hi-pot and resistance check on every unit |
| Layout service | Run and tap map per hall | Derived from your rack elevation drawing |
BUSWAY PRODUCTION PATH
Copper in, type-test out.
Copper forming
Bus bars punched, bent and stacked per ampacity class with plating and joint surfaces inspected.
Insulation wrap
Slot insulation and shrouds applied; creepage and clearance checked against the 600V rating.
Assembly
Straight sections jointed with torque-logged hardware; tap windows cut to your approved layout.
Temperature-rise type test
Sample runs carry rated current to IEC 61439-6 limits; every tap-off box passes a 100% pre-test.
DEPLOYMENT DETAIL
Overhead distribution that behaves like infrastructure.
Runs mount on standard threaded rod with telescoping joints absorbing building tolerances, so installs slot into weekend windows instead of outages. Each tap-off box reports its own current, letting DCIM see load at the point of change rather than only at the panel. Color-coded collars and phase markings keep future crews honest long after the original install team has rotated off the site.
FAQ
Busway questions we hear most.
Track busway or feeder busway — which do I need?
What does UL 857 cover, and how does IEC 61439-6 differ?
Can tap-off boxes really be added while the run is live?
How is every unit verified before shipping?
