摘要

Improvements in automatic control and protection equipment for electrical circuits, of the type that is organized in a general dielectric chassis and an equally dielectric plate that closes it and comprises, in combination: a fixed contact and a mobile contact-carrying arm; a mechanism for moving said movable arm and bringing it to the positions of closed or open circuit; an automatic trigger mechanism in which a thermosensitive element of bimetallic nature intervenes which, with its deformations, originates the movement of said movable contact arm to bring it to the open circuit position; a coil that upon being excited produces the firing of the device bringing said movable contact to the open circuit position; terminals for including said equipment in an electrical circuit, one of which connects with said thermosensitive element and allows some movement between the terminal and the bimetallic element; according to the improvements, a housing is provided in the dielectric chassis to receive, with absolute autonomy, the coil that causes, by magnetic effect, the release of the mechanism that opens the electric circuit, whose coil is retained on a chassis with a screw practicable from the outside of the chassis to regulate the moment of the shot according to which the coil is more or less next to the device of stirrup of the firing mechanism.
