Improved maximum circuit breaker system characterized essentially by the fact that it is constituted by two operating elements of which one of them is electromagnetic constituted by an electromagnet with axially mobile core equipped with means to mechanically act on the retained part of a body of contacts and the other element has an operating electro-thermal action due to the expansion of a bimetal sheet on the own body of the aforementioned retaining piece, this element cooperating with the previous one in order to always charge the excess amperage, both instantaneous and short-circuited and slow when it does not create the necessary magnetic field for the movement and action of the moving core, comprising the system a device for retaining the body of the contact piece, a tilting support for said body of contacts and external means operatively arranged so that by manual pressing the connection and disconnection are carried out at will depending on the automatic system of the apparatus.
