Abstract
Disclosed herein are efficient mechanical fuse devices that are capable of functioning at high current levels. These devices comprise mechanical features configured such that the fuse devices have a non-triggered state, which allows current to flow through the device, and a triggered state, which does not allow current to flow through the device. In some embodiments, the devices are configured such that a certain pre-determined current level flowing through the device will generate a sufficient electromagnetic field to cause the mechanical elements to transition the fuse device into the triggered state and thus interrupt a connected electrical circuit, device or system. In some embodiments, these devices can also comprise hermetically sealed components.
