PROPERTY OF CONTACT MATERIAL
The contact material of the vacuum circuit breaker should have the
following property.
The material should have high electrical conductivity so as to pass
normal load currents without overheating.
The contact material should have low resistance and high density.
The material should possess high thermal conductivity so as to
dissipate rapidly the large heat generated during arcing.
The material should have a high arc withstand ability and low
current chopping level.
