THE REFERENCE CONDUCTOR
• nVent ERIFLEX Flexibar is composed of multiple
layers of thin electrolytic copper, available in plain
(
Standard and Summum) or tin plated (Advanced &
Standard
• Flexibar connections are made by punching directly
through the laminates. There are no lugs to purchase,
which eliminates faulty connection problems and makes
installation easier and faster
• The insulation is a high-resistance, self-extinguishing TPE
(
Flexibar Advanced), Silicone (Flexibar Summum) or PVC
(
Flexibar Standard) compound
• Traceability code and designation Part Number
on product
• Easily formed, Flexibar improves assembly flexibility and
aesthetics of panels
• Optimal alternative to large cable & rigid busbar
• Quality: 100% production dielectric tested
• Full range from 24 mm

ENHANCED FLEXIBILITY
nVent’s exclusive manufacturing process offers
superiorflexibility:
• Copper laminates are free to slide within the insulation
• High insulation quality
• Wide variety of bending, twisting & folding possibilities
INNOVATIVE PATE NT I N SUL ATI O N
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 to reduce the contact surface
between the central conductor and the insulation material. This
results enhances the flexibility of the flexible busbar.
Result: <20% of the inner surface is in contact with the central
conductor.
This nVent ERIFLEX patent idea makes
ever and allows users to optimize the design of their electrical
power connection.
* This patent is applicable for the cross section indication by “*” on

WHY IS FLEXIBAR ADVANCED A
SAFER INSULATION?
Low smoke features:
• Generates less corrosive smoke ISO 5659-2
• Improves visibility for people to be able to easily locate the
emergency exit and also allows rescue workers to better assess
an emergency situation
The halogen–free feature enables:
• Reduction in the quantity of toxic smoke
• Minimum of toxicity with no halogens
(
according to IEC 60754-1
• Use in enclosed spaces for specific applications such as
submarines, switchboards, and other enclosed environments
that require a low emissions solution
The flame retardant portion of the test illustrates the
self-extinguish feature:
• Compliant with the UL 94-V0 Glow wire test @ 960°C
(
IEC 60695-2) testing standard
• Reduces the risk of the spread of fire
• Less damage to your electrical installation
)
• Conductor is electrolytic tinned copper (Cu-ETP
• Insulation is a high-resistance TEP Low Smoke.
Halogen Free and Flame Retardant (LSHFFR).
