ABSTRACT:
A bimetallic reed for a circuit protecting device includes an integral fusible portion as a failsafe interrupting mechanism. The bimetallic reed includes a body of electrical conductive materials and having a first end mountable to a terminal and a second end forming an interruptible contact portion. The body is shaped to deform at a central portion of the body when the body is heated to a predetermined temperature. The body includes a plurality of apertures adjacent to the contact portion defining a plurality of electrical conductive pathways connecting the central portion and the contact portion, wherein the plurality of conductive pathways is fusibly responsive to a predetermine electrical load condition to form a fusible link.
