Thermal triggering apparatus, for a protection device featuring an electrically conductive bimetallic strip and a plate of thickness (e) which supports the bimetallic strip. The bimetallic strip has a first end free that is capable of deforming and a second end or foot which is fitted into a cavity in the plate characterised in that the foot of the bimetallic strip passes through the cavity so that it protrudes below the bottom face of the plate by a length (a) that easily exceeds the thickness (e) of the plate, and the protruding part of the foot has an electrical connection point linked to a conductive part so as to form the direct heating element of the bimetallic strip.
