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 thermal overload relay of the type which uses a shifter to transmit thermal bending of the main bimetallic element to one end of the temperature compensating bimetallic element which is connected to a release lever which controls the closing of the relay and which includes an adjusting link which has an eccentric stem whose degree of rotation controls the setting of the release lever. As a calibration control to correct for unintended manufacturing variations and aging effects, the adjusting link supports an adjustment pin with an eccentric stem which abuts the eccentric stem of the adjusting dial to provide further control of the setting of the release lever.
