Product Application

Brass Busbar that are made from copper are preferred over aluminum Brass Busbar, electrical Brass Busbar because of the better electrical conductivity that copper bus bars offer. It is due to the greater electrical conductivity of copper, which enable installers to use smaller Brass Busbar if they are made of copper.
