Automatic current circuit breaker, essentially characterized by being constituted by a support plate carrying contact sockets, one of which connects with a thermo-electric resistance, from which part a conductor connected to a metal sheet carrying a mobile contact pole, and another lower bimetallic sheet provided with an insulating protrusion capable of slightly raising the upper sheet, and being located, between both sheets, a third sheet connected to the other outlet and provided with another mobile contact pole, coincident with the other upper mobile pole, and so, normally, both poles, by the elasticity of the carrier sheets thereof, tend always to be in permanent contact, interrupting said contact, and therefore the passage of current to the governed or regulated apparatus, by heating the bimetallic sheet heating produced simultaneously by the heat coming from the resistor electric incandescence and the heat directly transmitted by contact with the governed device, heating, when determining the rise of the insulating protrusion of the bimetallic sheet causes the displacement of one of the mobile poles separating it from the other, at which time the passage of current, whereby when the bimetallic sheet is relatively cooled, and when returning to occupy its normal position, the indicated circuit is restored, determining the resumption of the running of the governed device, and this, in a way, that both mobile poles tend to be permanently in contact through a pressure regulator.
