Copper Chromium Zirconium Contacts

Copper / Copper Zirconium / Copper Chromium / Copper Chromium Zirconium Current Carrying Parts (Non Arcing Contacts)

We offer complete range of current carrying Main Contacts, manufactured as per customer’s drawings & specifications in Copper/OFC, Copper Chromium, Copper Chromium Zirconium, Silver Bronze, Silver bearing Copper, CuZr etc.

Plant is well equipped with CNC Turning and Machining Centres having full-fledged in-house facility for full/ selective silver plating up to 100µm thickness. Silver plating can also be done selectively only on functional area as per customers requirement. All facilities under one roof helps in quick delivery of parts ready-to-assemble on the breaker pole.

Essentially non arcing contacts are made of CuCr/CuCrZr to carry current. They are generally silver plated on the legging of contact to avoid oxidation & current carrying part. Copper is preferred because of its electrical conductivity.

However, copper is having a disadvantage of losing its mechanical properties at elevated temperature for elevated temperature applications CuCr/CuCrZr is used. It can be supplied in various shapes and forms.
