Locking device, OFF position, for padlocking
The circuit breaker can be locked in the OPEN position with padlocks. It is therefore safety
locked, for example, for service and inspection work.
The two hinged covers can always be moved independently of each other and thus locked
individually.
Three different locking devices can be supplied for padlocks:
● Locking device made of plastic for up to three padlocks with a diameter of 4 mm (0.16")
● Locking device made of metal for one padlock with a diameter of 7 mm (0.28") or for a
padlock holder
● Locking device made of metal for up to 2 padlocks with a diameter of 8 mm (0.32")
This locking device fulfills the conditions for a supply disconnecting (isolating) device
according to EN 60204-1.
The locking device with padlocks can be used as an alternative to the protection device for
the ON and OFF buttons or as an alternative to the locking device for padlocks. It is not
possible to use both the protection device and the locking device for padlocking at the same
time.
The padlocks or padlock support are not included in the scope of delivery of the locking
device and must be provided by the customer.
