ABSTRACT:
An alarm indicator fuse (1) for large current and high temperature applications. The fuse assembly comprises apparatus (16, 121, 162) slidably engaging alarm indicator apparatus (14, 15) coupled between one conducting member (12) and a fuse element (13) electrically connected to another conducting member (11) to electrically couple the fuse element to the one conducting member and enable release of the alarm indicator apparatus upon opening of the fuse element. The electrically coupling and release enabling apparatus shortens the current path of the fuse between the electrical conducting members to increase the current capacity and improve the temperature characteristics of the fuse.
