Abstract
1,102,829. Heavy current switches; switch contacts. SQUARE D CO. 23 June, 1966 [1 Oct., 1965], No. 28126/66. Heading HlN. A contact structure for a low-voltage power circuit-breaker includes a contact frame 80 pivoted on a conducting shaft 76 and carrying a main contact pivot-pin 87 on which pivot several movable main contact arms 109 and the two legs 114, 115 of a hinge fork 116 providing part of the operating member, the fork 116 carrying a pin 120 on which pivots a movable arcing contact arm 121, and the shaft 76 carrying spring-pressed pivotable conducting contact pressure fingers 90, 90a for biasing the movable contact arms 109, 121, respectively. Movement of the operating member 129/128/116 causes the arcing contacts 41, 122, to engage before the main contacts 51, 110, the arcing contact arm 121 rotating about its pivot-pin 120 against the bias of fingers 90a, and then the main contact arms 109 rotating about pivotpin 87 against the bias of fingers 90 after contacts 51, 110 have engaged. The contact pressure is determined by springs 102. Upon break, the main contacts 51, 110 separate first (Figs. 8, 9, not shown)' A conventional magnetic trip means (not shown) is used for actuation. Eleotrodynamic forces hold the contacts closed.
