Zusammenfassung:An electrical switching apparatus (12) includes a plurality of poles (58, 60, 62), each of the poles including a terminal (4, 8, 4',8'). The terminal (4, 8') of a first one of the poles is proximate the terminal (8, 4') of a second one of the poles. A jumper (2; 32; 42; 52) is electrically connected between the terminal of the first one of the poles and the terminal of the second one of the poles. The jumper includes a plurality of heat transfer members (16, 18, 20, 22; 34, 36, 38, 40; 44, 46; 57), each of the heat transfer members being separated from others of the heat transfer members. L'invention concerne un appareil de commutation électrique (12) comprenant une pluralité de pôles (58, 60, 62), chacun des pôles comprenant une borne (4, 8, 4',8'). La borne (4, 8') d'un premier pôle est à proximité de la borne (8, 4') d'un second des pôles. Un cavalier (2, 32, 42, 52) est connecté électriquement entre la borne du premier des pôles et la borne du second des pôles. Le cavalier comprend une pluralité d'éléments de transfert thermique, (16, 18, 20, 22, 34, 36, 38, 40, 44, 46, 57), chacun des éléments de transfert thermique étant séparé des autres éléments de transfert thermique.
