Locking device, OFF position, Ronis lock
They are locked by a Ronis cylinder lock, which is installed in the operator panel. With this,
the circuit breaker can be locked in the OPEN position. The cover of the accessories
compartment can be removed when locked to enable maintenance work in this area.
If multiple circuit breakers are locked with cylinder locks, this can be implemented in two
versions depending on the lock numbers chosen:
●
Locks with different lock numbers: Each lockable circuit breaker has its own key.
The lock number can be selected from a choice of four different lock numbers.
●
Locks with the same lock numbers: Every key fits in every lockable circuit breaker.
The protection device with a key prevents access to the OFF button and the ON button
simultaneously. It is not possible to push both buttons. Access is only possible with the
relevant key.
This locking device fulfills the conditions for a supply disconnecting (isolating) device
according to EN 60204-1.
A Ronis cylinder lock is included in the scope of delivery.
Padlockable protective cover ON / OFF
With this version, one or both buttons can optionally be protected from being operated. If
only one button is protected, the other button can be operated.
●
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")
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 for padlocking can be used as an alternative for the protective cover
against unintended mechanical operation or as an alternative to the padlockable protective
cover ON/OFF. It is not possible to use both the protective cover 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.
