Claims

[Claims for Utility Model Registration] A normally closed movable contact having a normally closed contact at one end and an insulating plate at the other end is rapidly reversed by deflection of the bimetal to open the normally open contact, and In a thermal overcurrent relay that presses a normally open movable contact whose normally open contact is fixed by an insulating plate of the normally closed movable contact to close the normally open contact, a normally closed movable relay that presses the normally open movable contact. A thermal overcurrent relay characterized in that a locking portion for locking a normally open movable contact side end is provided on a side surface of an insulating plate end of a contact.
