FIELD: electricity.SUBSTANCE: in switchgear (1), which is a power circuit breaker preferably with at least one input terminal (2) and at least one output terminal (3) for connection of electric wires and with the first switching contact (4) and the second switching contact, at that switching contacts (4) in closed position close current circuit between input terminal (2) and output terminal (3); in this connection there is a circuit-breaker (5) for disconnection of the first switching contact (4) and the second switching contact, at that maximum current circuit-breaker (6) and/or short-circuiting switch (7) are envisaged which have mechanical link with gear lever (8) in order to actuate the circuit-breaker by the gear lever (8); at that gear lever has at least one first arm (9) and one second arm (10) of the lever; in what connection the first arm (9) of the lever has a control wedge in order to control maximum current circuit-breaker (6) and/or short-circuiting switch (7) and the second arm (10) of the lever has a control wedge (12) to actuate the circuit-breaker (5); the control wedge is of elastic type.EFFECT: prevention of damage in switchgear.10 cl |
