FIELD: electricity.
SUBSTANCE: invention relates to electrical devices. An interlocking device (2) for locking at least the first and second circuit breakers of an electric circuit, i.e. for preventing the simultaneous closed condition of the above circuit breaker, comprises two actuating arms (10R, 10L) moved independently between the first and second operating positions, which are coupled functionally to the first and second circuit breakers of the electric circuit respectively; the device contains also two kinematic mechanisms actuated by the actuating arms (10R, 10L).
EFFECT: preventing the simultaneous connection of the power consumer to two power systems.
