摘要

Protective circuit breaker for electrical distribution networks characterized by a circular electromagnet fixed on the front of a main frame of insulating material, with a rotary operating handle around its axis housed in the axial hole of the electromagnet, to which a lever is articulated with its fork-shaped end and the other free end, with a ratchet which can engage the driving roller of the oscillating bridge of the movable contacts subjected to the action of an opposing spring, and by whose movement, transmitted by the handle, is tighten the movable contacts against the fixed ones, elastically or not, to the main frame inside an extinguishing chamber.
