Abstract: An electromechanical rotary latch for use in current interruption devices disclosed. In a particular embodiment, a fuse device comprises a rotary latch; a rotatable armature configured to actuate the rotary latch; and a contact configured to change between a set position that allows current flow through the fuse device and a triggered position which interrupts current flow through the fuse device; wherein the fuse device is configured such that when a threshold current level passes through the fuse device, the rotatable armature changes configuration in response to a generated electromagnetic field, which actuates the rotary latch causing the contact to transition to the triggered position.

Abstract: A multipolar electrical protection system including a plurality of devices for switching an electric current. Each switching device has a plurality of compartments each comprising an extinguishing chamber and a pair of separable electrical contacts that are connected to upstream and downstream connection terminals, the separable electrical contacts being movable between open and closed positions under the action of a tripping device. The switching devices are separate from one another, while the upstream terminals of each device are connected by a first connector in order to keep them at one and the same electrical potential and the downstream terminals of each device are connected by a second connector in order to keep them at one and the same electrical potential. The switching devices are controlled by one and the same common tripping device.
