Abstract
Described is a fuse for an electrical circuit, comprising two contact arms, each having at least one connecting pin for inserting into a hole of a printed circuit board, and a spring which connects the two contact arms in an electrically conductive manner. According to this disclosure, it is provided that the spring is fastened to at least one of the two contact arms by means of a fastening means that loses its strength at a trigger temperature of the fuse, wherein the fuse is formed in such a manner that by inserting the connecting pins into holes of a printed circuit board, the spring is loaded such that the spring lifts from the at least one contact arm by spring force as soon as the fastening means loses its strength due to overheating. Moreover, a printed circuit board comprising such a fuse is described.
