Abstract

A current-limiting fuse for an electronic apparatus, such as, for example, a transformer. The fuse can be withdrawable under a liquid insulating medium, such as oil, and is capable of being replaceable in the field. The fuse can include a fuse element that is encased within an electrically insulative sheath. Additionally, a plurality of contact blades can extend from a lower portion of the fuse and be securely engaged with contact clips that are in electrical communication with one or more components of the electronic apparatus. The contact blades can be positioned within a dielectric insulating medium while a reminder of the fuse between the contact blades and the enclosure can be positioned within an air gap. Further, the contact blades can accommodate seating of the fuse within the enclosure and/or an associated canister.
