The present invention concerns a method and a device for locking a disconnecting breaker. During locking of a single-poled or multiple-poled disconnecting breaker, the actuator of the breaker is first locked both electrically and mechanically. When the breaker is in the open position, the distance between the contacts of the breaker comprises the conductor spacing for the isolation function. The electrical and mechanical locking of the actuator is indicated both electrically and mechanically. Subsequently, the link system of the breaker is mechanically locked. The link system is locked in the interlocked position. Locking of the link system is indicated by at least one indicator. Locking of the actuator of the breaker can be controlled manually via a key- and lock device, or remotely.
