Claims

[Scope of utility model registration request]

a crossbar that is engaged with a reversing movable part for a normally closed contact that performs a reversing operation, moves in a direction to open the normally closed contact by the reversing action of the reversing movable part, and closes the normally open contact by this movement; A thermal actuator equipped with a contact mechanism that is supported movably in a direction perpendicular to the movement direction and has a reset bar that returns the crossbar in the state after the movement and both contacts to the state before movement by pressing the crossbar. In the type overcurrent relay, the pressing piece is integrally formed with the reset bar, and when pressed together with the reset bar further than the pressing position, it engages with the cross bar and causes the cross bar to close to the normally closed contact. 1. A thermal overcurrent relay comprising a pressing piece having an engaging portion that moves the relay in the opening direction.
