A repeatable fuse is provided to reduce temperature deviation by varying the line thickness of a shape memory alloy spring according to the shape memory alloy. A repeatable fuse includes a base part(100), a first lead terminal(112), a second lead terminal(114), a contact plate(130), and an elastic member(120). The base part has a base plate and a first protrusion. The first protrusion is formed in one side of the base plate. The contact plate and the elastic member are arranged in one side of the base part. The first and second lead terminals are electrically connected to the contact plate and the elastic member. The first and second lead terminals are exposed to the other side of the base part. An elastic member includes a main spring and an auxiliary spring. The contact plate is arranged between the main spring and the auxiliary spring. At least one of the main spring and the auxiliary spring includes the shape memory alloy.
