Abstract
(EN) A jumper (100,200,300) is for an electrical switching apparatus (2,2') having a plurality of poles (6,8,10,12; 6',8',10',12'). Each of the poles (6,8,10,12; 6',8',10',12') comprises a terminal (14,16; 14',16'). The terminal (14,14') of a first one of the poles (6,6') is proximate the terminal (16,16') of a second one of the poles (8,8'). The jumper (100,200,300) includes a jumper member (102,202,302) having an attachment portion (104,204,304) and a heat sink portion (106,206,306). The attachment portion (104,204,304) is structured to electrically connect the terminal (14,14') of the first one of the poles (6,6') to the terminal of the second one of the poles (8,8'). The heat sink portion (106,206,306) includes a plurality of spaced apart heat transfer members (108,208,308) that are arranged in a plurality of rows (110,210,310) and a plurality of columns (120,220,320).
(FR) L'invention concerne un cavalier (100, 200, 300) qui est destiné à un appareil de commutation électrique (2, 2') ayant une pluralité de pôles (6, 8, 10, 12 ; 6' ,8', 10', 12'). Chacun des pôles (6, 8, 10, 12 ; 6' ,8', 10', 12') comprend une borne (14, 16 ; 14', 16'). La borne (14, 14') d'un premier des pôles (6, 6') est à proximité de la borne (16, 16') d'un second des pôles (8, 8'). Le cavalier (100, 200, 300) comprend un élément de cavalier (102, 202, 302) ayant une partie de fixation (104, 204, 304) et une partie de dissipateur thermique (106, 206, 306). La partie de fixation (104, 204, 304) est structurée de manière à connecter électriquement la borne (14, 14') du premier des pôles (6, 6') à la borne du second des pôles (8, 8'). La partie de dissipateur thermique (106, 206, 306) comprend une pluralité d'éléments de transfert de chaleur (108, 208, 308) espacés les uns des autres qui sont agencés en une pluralité de rangées (110, 210, 310) et en une pluralité de colonnes (120, 220, 320).
