CA 2196578

An interlock assembly is provided for a fusible switch which has a fuse in series with a switch and an operative mechanism for controlling the operation of the switch. The interlock assembly is mechanically coupled to the operating mechanism and includes an indicator member disposed adjacent to the fuse for indicating the status of the fuse and an actuator member mechanically coupled to the operating mechanism for actuating the operating mechanism to open the switch when the fuse is BLOWN. A toggle member may be coupled to the indicator member and to the actuator member for mechanically communicating the status of the fuse to the actuator member from the indicator member wherein the toggle member is in one position when the fuse is CONDUCTIVE and the toggle member is in an another position when the fuse is BLOWN.

L'invention porte sur un ensemble d'interconnexion (12) pour coupe-circuit (10) à fusible comportant un fusible (44) monté en série avec un coupe-circuit, et sur un mécanisme de commande (32) régissant le fonctionnement du coupe-circuit (10). L'ensemble d'interconnexion (12), relié mécaniquement au mécanisme de commande (32), comporte un indicateur (14) adjacent au fusible (44) indiquant l'état dudit fusible (44), et un élément actuateur (16) relié mécaniquement au mécanisme de commande (32) et agissant sur le mécanisme de commande (32) pour ouvrir le coupe-circuit (10) lorsque le fusible (44) a sauté. Un élément basculant (18) est relié à l'indicateur (14) et à l'élément actuateur de manière à communiquer mécaniquement à l'élément actuateur (16) l'état du fusible (44), l'élément basculant (18) se trouvant dans une position lorsque le fusible (44) est conducteur, et dans une autre position lorsque le fusible (44) a sauté.
