ReliaGear® High Power Busway for commercial and industrial applications uses less space and material


The new ReliaGear® High Power Busway from ABB Electrification Products division, available in copper and aluminum, provides an efficient and economical alternative to power cabling in building and industrial applications that occupies less space and uses less material.
  • ReliaGear High Power Busway is UL® 857 Listed
  • It also features factory-mounted copper or aluminum conductors that deliver power to electrical loads
“The new ReliaGear High Power Busway has a rating of 600 volts,” said Senthil-Kumar Natarajan,  local busway product manager, ABB Electrification Products division. “The busway’s totally encased, non-ventilated, low-impedance sandwich construction makes it ideal for indoor power-to-load applications in a variety of construction and manufacturing environments.”

The copper or aluminum conductors are epoxy resin coated, and are available in tin or silver-coated finishes. The bar is housed in aluminum casing that grounds the busway and is available in indoor-feeder, indoor plug-in and sprinkler-proof configurations, as well as ingress protection ratings of IP55 and IP67. It also is available with multiple bar configurations to suit project requirements, such as neutral, double neutral, ground and half ground.

ReliaGear High Power Busway ranges up to 5,000 amps in copper and 800-4,000 amps in aluminum, with a maximum six-cycle RMS symmetrical short-circuit rating of 200kA.

Elbows, offsets, flanges, tees, end and center feed units, expansion units, and splices that are commonly required for busway installations are also available, as well as installation hangers. Bus plugs with fusible switches or circuit breakers are available 15-800 amps. There are up to five bus plug points for each side on a 12-foot length. All bus plugs have mechanical/electrical interlocks with a ground-first/break-last safety feature. A patented process for pressed-out tags for bus plug connections is also available. 

ReliaGear High Power Busway is painted RAL 7035 gray, with other colors available upon request.  Joint-pack construction with double-headed shear nuts provides quick installation.

In addition to being UL857 Listed, ReliaGear High Power Busway is manufactured in a certified management system environment where Quality ISO 9001, Safety OHSAS 18001 and Environmental 14001 standards apply to all aspects of manufacturing and installation. It also meets NEMA, CSA (cUL), IEEE, ANSI, IEC and CE requirements. ReliaGear High Power Busway is certified for seismic withstand capability and has a qualification level of High (Zone 5) in accordance with IEEE standard 693-2005.
