Abstract

La resistenza comprende una guaina tubolare (11) di protezione del resistore e mezzi interruttori termosensibili di protezione da sovratemperature. Tali mezzi includono contatti fissi e mobili (22a-24a-26a-26b), normalmente chiusi, ed organi spintori (27) per l'apertura rapida dei contatti. Gli spintori sono soggetti a rispettivi mezzi elastici precaricati (33) normalmente mantenuti in posizione tensionata da elementi di ritegno (31) vincolati da arresti (35) di materiale termofusibile associati alla guaina (11). Al superamento di una prefissata temperatura della guaina, gli arresti (35) fondono liberando i mezzi elastici (33) che producono l'apertura dei contatti. (Rif. Fig. 3).
