MECHANISM OF CIRCUIT BREAKER FOR SUNK ELECTRICAL DEVICES Russian patent published in 2013 - IPC H01H23/04 

FIELD: electricity.

SUBSTANCE: mechanism of a circuit breaker for sunk electrical devices is designed for placement in a central hole (5a) of a frame (5) and being fixed by clamps (7) to a fastening plate (6), is integrated in a sunk unit of an electrical device. The mechanism comprises a body (1), inside of which there are electric contacts, and a cover (2), which is fixed to the specified body (1). From the upper rectangular hole of the cover a rocking lever (3) appears, rotary motion of which prompts a rotary contact (21), installed inside the body (1), to move. The rocking lever (3) rotates from outside whenever the element (4) of the external working element fixed on the rocking lever (3) by means of ledges on its lower side, which are inserted into ribbed holes (17) in the upper part of the specified rocking lever (3) is activated. Side surfaces of the cover (2) have guides (8) for positioning above contacts (9) on the outer sides of the body (1), sent in this positioning motion by vertical flanges (10), making it possible to install and fix the cover (2) on the body (1). Two ends of the cover (2) have grips (14), which make it possible to fix the assembly of the body (1) and the cover (2) to the fastening plate (6).

EFFECT: possibility to be configured in a different manner in one closed element, which may simply be installed in a frame and a support of a sunk unit.
