録請求の範囲第１項記載の熱動式過電流継電器。[Claims for Utility Model Registration] (1) It has a movable contact made of a thin spring material and has two cantilever parts, namely an outer beam part and an inner beam part, and the end part of the movable contact is A pressing plate spring is fixed to the normally closed movable side terminal and is pressed into engagement between the outer beam portion and the inner beam portion of the movable contact, and the movement of the thermal element provided for each phase is controlled by the inner beam portion. In the thermal overcurrent relay, a contact portion is provided on the outer beam portion, and a normally closed fixed terminal is provided opposite to the contact portion to form a snap-operated normally closed contact. 1. A thermal overcurrent relay comprising means for restraining a substantially central portion of the inner beam in a direction opposite to the direction in which the thermal element operates. (2) The scope of the utility model registration claim, characterized in that the substantially central portion of the inner beam is restrained by the engagement between the bent portion provided at the center of the inner beam and the extension of the normally closed movable side terminal. The thermal overcurrent relay according to item 1.
