TRIPPING MECHANISM PROTECTING FROM RESIDUAL CURRENT AND TRIPPER Russian patent published in 2015 - IPC H01H71/10 

FIELD: electricity.

SUBSTANCE: tripping mechanism (102) is used together with the devices protecting from residual current, from overload and from short circuit. The tripping mechanism (102) contains a tripping bar (20) and a hammer (30) coupled with it which moves between the working position and the tripping position. The tripping bar (20) has the first (23) and the second (22A-22C) tripping sections, the first of which interacts with the bar (40) of the device, protecting from residual current, making the tripping bar (20) to move the hammer (30). The second tripping section interacts at least with one of the devices protecting from overload and from short circuit, making the tripping bar (20) to move the hammer (30).

EFFECT: prevention of cases when the mechanism can be not tripped in case of short circuit or incorrect tripping.
