Abstract (en)
[origin: EP0175349A2] A vacuum circuit breaker has a vaccum vessel (2) in which are disposed a pair of opposing electrodes (8, 9) so as to be moved into and out of contact with each other, each of the electrodes (8,9) being made of a material consisting essentially of a main component such as Cu, Ag or the like and a low-melting point metal such as Bi, Pb, Te, Se or the like. A film (13) is formed on the surface of each electrode (8, 9) by, for example, evaporating a metal having a melting point equal to or higher than that of the main component of the electrode material.
