For power transmission & distribution, busbars are the main electrical conductors in an electrical control panel that supply current to all consumers in the cabinet. The traditional busbar technology is beset with problems like large size, inconsistent material, connections through holes and fasteners, slow and labour-intensive assembly process, metal corrosions and similar. With an open execution, traditional busbars are also inherently unsafe to the people working in the electrical panel.

Traditional busbars did not have competition, until Wöhner® busbars became available. With their cohesive and modular approach, Wöhner® electrical busbar systems offer outstanding advantages over their traditional equivalents.



For over 90 years, the name Wöhner® has been synonymous with top performance and technology innovation. With over 100 registered patents, it is well known and recognised worldwide as a competent and reliable partner for energy distribution - a specialist for international fuse and busbar systems.



  •          Compliance with IEC 61439and UL 508 standards including IP20 touch-safe protection.
  •          Small size of busbar with close stacking pitch, resulting in significant reduction of panel                       dimensions.
  •          Inherent safety due to touch-safe, all-around covered construction.
  •          Direct mounting on DIN rails, without use of external busbar supports.
  •          Speed of installation, the busbars and their connected components can be installed and wired               without any drilling, tapping, or crimping of lugs.
  •          Clamp-on connections ensures that busbar is not drilled and there is no loss of metal mass.
  •          Simplicity and convenience with snap-fitting and clamping of parts
  •          Ease of expansion by stacking other busbar modules
  •          Compatibility with all standard switchgear that directly mount on the busbar.
  •          Adaptability with various Wöhner® supplied functional modules that mount directly on the                   busbars.
  •          Long, corrosion-free life.
  •          Free online utilities to help busbar user:

o   Configure the busbar selection and design.

o   Calculate the current metal surcharge.

o   Verify design as per IEC 61439 standards.

o   Calculate current carrying capacity, thermal derating, and short-circuit capability of busbars.

o   Shortlist the adaptor and connector types.

  •          The reports generated from online utilities can certify compliance to mandatory IEC 61439 and             UL 508 standards without requiring expensive consultancy, or laboratory tests.
