Bi-Metallic Circuit Breaker Lug
B20

Description

TriCab Bi-Metallic lugs are specifically designed to terminate our flexible aluminium cables without the need for Copper Tails or Reducing Links. This saves enormous installation cost and time. They are manufactured using a friction welding process, which provides optimal transition between aluminium barrel and copper palm.

Suitable for TriCab ALI-FLEX cables only.
