ABSTRACT:
Withdrawable racks for power circuit breakers should be reliably switched. To this end, the movement of the plates of a shutter in the withdrawable rack can be blocked so that the shutter is not permitted to open unintentionally. In a special embodiment, the opening mechanism for the plates can have two V-shaped linkages that are connected to a telescopic rod. The telescopic rod can be locked by a locking element so that the shutter plates, which can be moved by sliders, can no longer be displaced.
