An extra-sensitive circuit breaker, characterized by the fact that the hand-operated lever, interposed between the two terminals of the circuit to be protected, is resolved in three different essential organs and articulated with each other; of which one is a hinged lever articulated with an axis supported by two pins connected to one of the two terminals of the switch; subjected this lever to the reaction of a spring, and connected to this terminal; the second organ consists of a profile lever U that surrounds the first one, articulated with the aforementioned axis itself, but electrically isolated from this axis because its bearing bearings are insulating; and the third organ consists of a bridge articulated with an axis supported by the fins of the lever in U, subjected to the reaction of a spring of its own, and that when connecting supports its legs, on the lateral plates of the piece in which it is supports the axis of the anchor that will fit with the hole provided in the U, and in which piece is fixed one of the ends of the thermoreatable conductor that determines the rotation of that axis, and that is fixed and connected by its other end with the another terminal of the circuit to be protected.
