Padlock device for the handle

The padlock device for the handle is directly attached to the handle of the 3VA molded case circuit breaker and latched in place.

NOTE

For installation instructions, please refer to operating instructions "Padlock device for the handle".

When the padlock device for the handle is installed, the 3VA molded case circuit breaker can be locked in the OFF (O) position by up to three padlocks (shackle diameter 4.5 to 8.5 mm).

If the application requires the 3VA molded case circuit breaker to be locked in the ON (I) position as well, the metal pin ① must be removed by pliers from the handle, see illustration below. This deliberate action is a safety precaution and prevents accidental locking of the breaker in the ON position.
