ABSTRACT:
A fusible link having two body members separably coupled to one another and normally prevented from separating by a collapsible strut. One body member has an opening in which the other body member is slideably accommodated, such other body member having an abutment which bears against the body at one marginal edge of the opening. The strut is accommodated within the opening and reacts between the two body members to preclude movement of the slideable body to a position in which the abutment can pass through the opening in the other body. The strut includes a eutectic alloy which melts when its temperature rises to a predetermined level. Melting of the eutectic alloy permits the overall length of the strut to shorten by an amount sufficient to permit the abutment on the slideable body to pass through the opening in the other body and effect separation of the bodies.
