Abstract
Electrical cut-off device including a fuse used to open a power line in which a direct current circulates, a movable drawer connected to the fuse and capable, once the fuse is broken, of moving in a fixed chamber under the action of a compression spring mounted between the fixed chamber and the movable drawer, and an auxiliary contact whose fixed contact part is secured to the fixed chamber and movable contact part is secured to the movable drawer whose movement will cause the opening of the normally closed auxiliary contact.
Claims11
An electrical cut-off device including a fuse used to open a power line in which a direct current circulates, wherein the electrical cut-off device further includes a movable drawer connected to the fuse and capable, once the fuse is broken, of moving in a fixed chamber under an action of a compression spring mounted between the fixed chamber and the movable drawer, and a normally closed auxiliary contact whose fixed contact part is secured to the fixed chamber and movable contact part is secured to the movable drawer whose movement will cause the opening of the normally closed auxiliary contact, wherein the normally closed auxiliary contact is galvanically isolated from the power line.
An electrical cut-off device including a fuse used to open a power line in which a direct current circulates, wherein the electrical cut-off device characterized in that it further includes a movable drawer connected to the fuse and capable, once the fuse is broken, of moving in a fixed chamber under an action of a compression spring mounted between the fixed chamber and the movable drawer, and a normally closed auxiliary contact whose fixed contact part is secured to the fixed chamber and movable contact part is secured to the movable drawer whose movement will cause the opening of the normally closed auxiliary contact, wherein the movable drawer is fixed to one end of the fuse by a first fixing screw.
An electrical cut-off device including a fuse used to open a power line in which a direct current circulates, wherein the electrical cut-off device characterized in that it further includes a movable drawer connected to the fuse and capable, once the fuse is broken, of moving in a fixed chamber under an action of a compression spring mounted between the fixed chamber and the movable drawer, and a normally closed auxiliary contact whose fixed contact part is secured to the fixed chamber and movable contact part is secured to the movable drawer whose movement will cause the opening of the normally closed auxiliary contact, wherein the movable drawer is made up of a slide sliding in the fixed chamber and of a stopper bearing against the fixed chamber and fixed to the slide by a second fixing screw.
