Description

Arc Resistant Busway System Tested to IEC 61641

The OH-DCB-ARC series is for runs where incident energy at the main distribution level is high enough to drive the arc flash boundary beyond the available working space. Pressure relief paths, reinforced joint covers and front only access are combined with IEC 61641 testing at 50kA so the containment claim is supported by a test report rather than a design note.

Key Features

  • IEC 61641 Arc Tested: Verified containment with indicator cloth test at joint and tap off positions
  • Pressure Relief Paths: Rear and top relief flaps with flame arrestor direct gas away from operator side
  • Reinforced Joint Covers: 3.0mm steel at joint zones resists deformation during an internal arc event
  • Front Access Design: Operator side stays clear so maintenance follows arc flash boundary rules
  • Labels and Boundaries: Arc flash labels and boundary drawings supplied with every run

Applications

  • Main distribution busway fed directly from the transformer
  • AI data center white space with limited arc flash boundary distance
  • Facilities audited against NFPA 70E incident energy limits
  • Brownfield upgrades where upstream protection cannot be changed
