Lockability

The removable locking device integrated into the handle is suitable for padlocks with a shackle diameter of 4.5 to 8.5 mm (locks according to DIN 7465).

Up to three padlocks with a shackle diameter of 8.5 mm and up to five padlocks with a shackle diameter above 6 mm can be used.

Non-interchangeability

In order to ensure that all the components ate assembled together in the correct order when installing control and door-coupling rotary operating mechanisms, they are equipped with non-interchangeability features (rivels and lugs).

Stops

Stops serve to prevent damage owing to excessive torque. These are supplied loose with the rotary operating mechanisms and can be installed on need. Stops are fitted at the factory to size 1 and 2 rotary operating mechanisms with a 90° operating angle (exception: 3RV motor starter protectors).

tolerance compensation

8UC7 rotary operating mechanisms are capable of taking up a radial eccentricity of max. 3 mm between the actuating shaft of the switching device and the operating mechanism. Supporting the extension shaft is recommended with greater tolerances.

Permissible radial eccentricity and axial tolerance compensation in mm

Pull-out strength

The pull-out strength of interlocked operating mechanisms, e.g. pulling off the shaft or destruction of the operating mechanism, amounts to 800 N when the pulling force acts directly onto the operating mechanism in direction of shaft.
