CA 2425714

An externally controllable circuit breaker includes a set of main contacts, an operating mechanism for opening and closing the main contacts; and a set of secondary contacts electrically connected in series with the main contacts. A control mechanism to open and close the secondary contacts includes an electromagnet with an armature having a first position, which opens the secondary contacts, and a second position, which closes the secondary contacts. The electromagnet also includes a coil electrically interconnected with the main contacts for energization therefrom and adapted for control by one or two external signals from one or two external contacts to operate the armature between the first and second positions.

Disjoncteur à commande externe comprenant une série de contacts principaux, un mécanisme de commande pour l'ouverture et la fermeture desdits contacts et une série de contacts secondaires reliés électriquement en série avec les contacts principaux. Un mécanisme de commande pour l'ouverture et la fermeture des contacts secondaires comprend un électro-aimant avec une armature ayant une première position qui ouvre les contacts secondaires, et une seconde position qui ferme les contacts secondaires. L'électro-aimant comporte également une bobine reliée électriquement aux contacts principaux pour les mettre sous tension et adaptée pour être commandée par le biais d'un ou de deux signaux externes d'un ou de deux contacts externes afin de commander la position de l'armature entre la première et la seconde positions.
