Abstract
A vacuum circuit interrupter characterized by an evacuated housing containing a pair of separable electrical contacts which can generate an arc when separated to an open position. An electromagnetic structure for diffusing the arc radially from between the electrical contacts to transfer contacts surrounding each electrical contacts and including an axial magnetic coil and including a cylindrical conductor surrounding a longitudinally movable electrode mounting one of the electrical contacts. The housing includes an end wall through which the electrode extends in a vacuum-tight and electrically insulated manner. The end wall having a high coefficient of electrical conductivity and having an annular portion extending outwardly from the end wall for good electrical contact with a bus conductor.
