The rotary lever drive for 2- to 4-pole devices is available for mounting on the switchboard door. Due to the ergonomic shape of the rotary lever, switching is particularly effortless. It features a lockable mechanism for the OFF position, which prevents the high-performance circuit breaker S800 from being turned on. The lockable mechanism's elongated hole can accommodate up to 3 padlocks with a shackle diameter of 7 mm (not included). The operation of the release and visibility of the identification data are not obstructed. Additionally, a rotary lever drive for machine switching is also available, which has a red handle on a yellow background.
