摘要： A thermal overload relay includes an inversion operation mechanism that is driven by a releasing lever to open or close a contact. The inversion operation mechanism includes a movable plate supported at one end so as to be inverted, and a tension spring for driving the movable plate for inversion. The releasing lever presses a middle of a wire of the tension spring to drive the movable plate for inversion. A projection is formed in the middle of the wire of the tension spring to contact with the releasing lever. Thus, a stable inversion operation can be made regardless of the positioning of an adjustment dial.

摘要： A reset rod (43) of a thermal overload relay is configured to be switchable between a manual reset position in which a reversal mechanism (21) is manually returned to an initial state prior to reversal by performing a pushing-in operation, and an automatic reset position in which a pushed-in state is held by a pushing and rotating operation from this manual reset position, and the reversal mechanism (21) is automatically returned to the initial position. In addition, axial runout restriction portions (17b, 17d, 51, 46 and 47), which restrict axial runout of the reset rod (43) when the reset rod (43) is held in the automatic reset position, are provided.
