Abstract

a. Dispositif de coupure pour circuits électriques. b. Ce dispositif comprend un fusible permanent et des résistances en parallèle sur celui-ci par l'intermédiaire d'un conducteur de liaison, l'ensemble étant branché entre une source d'énergie électrique et une charge afin de couper l'alimentation de celle-ci en cas de courts-circuits. Selon l'invention, au moins les surfaces extérieures des résistances en parallèle, voisines des éléments reliés au conducteur de liaison sont couvertes d'un revêtement isolant. c. Protection des circuits électriques.
