Abstract

The device prevents the blade from flying out under centrifugal force in the event of a short circuit and has an element (24) for transferring a blocking force directly from the contact arrangement (3) to the isolating blade in the event of a short circuit. The element can move, especially pivot, essentially in a plane perpendicular to the longitudinal axis of the isolating blade.
