Abstract

Improvements in the electrical circuit breakers, with fixed and mobile contacts and with a mechanism that includes a handle to manually operate the circuit breaker, a shaft fixed in the circuit breaker case, a lever with two arms of unequal length, pivoting this lever on said shaft and it can be rotated in the direction of the circuit breaker interlock by the handle, and a helical spring with legs, set on the same shaft and acting on said two-arm lever, characterized in that the shaft (1) also has a slotted lever (2) mechanically coupled to the handle (5), because the arms of the two-arm lever (3) form an angle of approximately 90º with each other, the vertex of which coincides approximately with the shaft (1) and because the mobile contact (4) is mounted on the short arm of the two-arm lever (3).
