ABSTRACT:
A circuit protector is connected in a circuit to protect the circuit from overloading. The circuit protector includes a casing inside which first and second terminals electrically connected to the circuit are fixed. A first cantilever member is fixed to the first terminal and has a cantilever arm that assumes a first shape in a normal condition and is convertible into a second shape in an overloading condition. A second member is supported in the casing by a pivot and has one end fixed to the second terminal by a fastener and an opposite end forming a contact engageable with the cantilever arm in the first shape and separable from the cantilever arm in the second shape. The fastener has a low melting point whereby an overloading causes the fastener to melt and break and thus allowing the second member to rotate and separating the contact from the cantilever arm. The second member is biased by a spring to facilitate separation of the contact from the second member when the fastener is broken.
