The invention concerns a safety device for monitoring heat for connections in electrical installations. Said device comprises a first connecting element (14) in thermal relationship with an electrical connection to be monitored. A second element (35) is also designed to be connected to the ground of the general electric installations. Electrical connecting means (21) connect said two elements and can adopt two states, one an insulating state in normal operating conditions and the other an interrupting state wherein there is contact and hence earthing of the first element with the second when a critical temperature is reached.
L'objet de l'invention est un dispositif de surveillance thermique de sécurité pour des connexions dans les installations électriques. Un tel dispositif comprend un premier élément de liaison (14) en relation thermique avec une connexion électrique à surveiller. Un second élément (35) est également prévu pour être relié à la terre de l'installation électrique générale. Des moyens (21) de connexion électrique relient ces deux éléments et peuvent prendre deux états, l'un isolant en fonction normal et l'autre de rupture dans lequel il y a contact et donc mise à la terre du premier élément avec le second lorsqu'une température critique est atteinte.
