Abstract

723,837. Arc-rupturing in switches. ETABLISSEMENTS MERLIN & GERIN. Oct. 13, 1952 [Oct. 15, 1951], No. 25562/52. Addition to 702,834. Class 38 (5). .The centre C of the surface, against which the arc develops, of each insulating plate of the parent Specification is so spaced from the tips of A, B of the conducting components 3, 4 that the angle A C B is equal to or less than 45 degrees. Spacing members 11 between adjacent plates limit sideways expansion of the arc.
