The rotary lever drive for 2- to 4-pole devices is available for mounting on the control panel door. The ergonomic shape of the rotary lever makes switching particularly effortless. It has a lock for the off position, which prevents the S800 high-performance circuit breaker from being switched on. The slot in the lock can accommodate up to 3 padlocks with a shackle diameter of 7 mm (not included). The operation of the release and the view of the characteristics are not obstructed. A rotary lever drive for switching machines is also available, which has a red handle on a yellow background.
