More Information
Summary: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.
