A fault protection device such as a fuse may have a body portion and a displaceable portion mounted to the body portion and displaceable from the body portion as a result of use or operation of the fault protection device. An authentication device is secured to the fault protection device. The authentication device may have a first portion secured to the body portion and a second portion secured to the displaceable portion in a manner that removal of the first portion or the second portion from the body portion and the displaceable portion, respectfully, results in irreparable damage to the authentication device. Furthermore, displacement of the displaceable portion from the body portion as a result of use or operation of the fault protection device results in irreparable damage to the authentication device. The authentication device may also include verifiable indicia authenticating a characteristic of the fault protection device as being genuine.
