Abstract
A protective thermal device for manual replacement for electrical appliances, comprising a bimethal disk with a convex shape carrying two movable contacts, designed to reverse automatically by firing its curvature, interrupting the circuit, when it is exposed to a temperature higher than a preset value and to be returned by hand by firing to the normal curvature when it is desired to restore the circuit, characterized in that it comprises a base of insulating material, intended to be fixed on the apparatus to be protected, having a substantially cylindrical shape, with an internal step, in the wall intended to be close to the apparatus to be protected and an external step in the remote part of the apparatus itself, and a central body, also made of insulating material, carrying the bimetal disk, on which the two mobile contacts are applied, and two contacts fixed, intended to cooperate with the two mobile contacts and extending radially to the exterior with respect to the central body so as to form two terminals substantially coplanar with the fixed contacts, and by the fact that the central body is mounted inside the base, free to run axially with respect to the base itself, connected to it in the sense of its distance from it by the application of a step of the central body with the external step of the base, the bimetallic disk having such dimensions that it is appropriate to contact the inner step of the base.
