Abstract
The thermal cutout comprises a casing (1) in which at least a portion of casing (3) is of heat-conducting material, two terminals (5) carried by an electrically insulating plug (4) and an electrically conductive moving element (6) maintained in contact with each terminal (5) by a member (8) which is deformable under the action of heat and which is in turn in contact with the heat-conducting portion of casing (3). The cutout essentially comprises a translationally displaceable electrically insulating member (7) forming a separation between on the one hand the heat-deformable member (8) and on the other hand the terminals (5) and the electrically conductive element (6).
