ERIFLEX® FLEXIBAR Flexible Insulated Busbar


ISO 9001 certified quality control procedures and proprietary automated manufacturing processes have made ERIFLEX® FLEXIBAR a preferred conductor for panelboard designers and assemblers throughout Europe and the Americas. ERIFLEX FLEXIBAR has a long history of proven low voltage application success throughout the world.


ERIFLEX FLEXIBAR has added grooves on the inner surface of the insulation sleeve to improve sliding between the central conductor and the insulation material. The grooves help reduce the contact surface between the central conductor and the insulation material. This results in improved flexibility of the flexible busbar. Result: 20% of the inner surface is in contact with the central conductor. This innovative insulation design makes ERIFLEX FLEXIBAR more flexible than ever, and allows users to optimize the design of their electrical power connection.



  • ERIFLEX FLEXIBAR consists of a stack of thin copper laminates (available in plain or tin plated) and protected within a durable PVC insulation
  • Internal copper laminates are free to slide within the insulation, offering a wide variety of twisting and bending possibilities for panelboard assembly
  • Terminals are created by punching ERIFLEX FLEXIBAR laminates for optimum surface to surface connectivity
  • The cost of lugs and associated labor is eliminated when using ERIFLEX FLEXIBAR. It is a cost effective alternative to large diameter electrical cable with lugs or solid busbar for panelboard construction
  • The insulation is a high-resistance, self-extinguishing PVC or silicone compound
  • Traceability code and designation Part Number are marked on product
  • Easily formed, ERIFLEX FLEXIBAR improves assembly flexibility and aesthetics of panels
  • Ideal alternative to large cable & rigid busbar
  • Quality: 100% production dielectric tested
  • Full range from 27 mm2 up to 1200 mm2



  • Working temperature -25ºC up to 105ºC (-13ºF up to 221ºF) ERIFLEX FLEXIBAR
  • AWM Style 11343 Nominal voltage = 1000 V AC/1500 V DC (IEC & UL®)
  • Self-extinguishable
  • High mechanical resistance
  • High elongation value
  • High current withstanding
  • High copper quality (99.9% purity)
  • High conductivity
