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: Component assemblies and methods of manufacturing component assemblies that include a magnetic yoke assembly for electromechanical contactors and relays are disclosed. In a particular embodiment, a component assembly that includes a magnetic yoke assembly for electromechanical contactors and relays is described. In this embodiment, the magnetic yoke assembly includes a movable contact and a ferromagnetic upper yoke mounted in above the moveable contact and separate from the moveable contact. The magnetic yoke assembly also includes a ferromagnetic lower yoke mounted under the moveable contact.
