Abstract
A breaker comprises: a first terminal piece on which a fixed contact is formed; a movable piece having a movable contact, for pressing the movable contact against the fixed contact so as to contact therewith; a thermally-actuated element deforming with a change in temperature and moving the movable piece so that the movable contact is separated from the fixed contact, and a second terminal piece electrically connected to the movable piece. The movable piece is provided, within a contact portion contacting with the second terminal piece, with a protrusion projecting toward the thermally-actuated element.
