Each of the locking devices listed here is available in versions for the fixed and withdrawable
breaker versions.
● Fixed breaker:
To mount the modules on a fixed breaker, the side wall must be modified so that the main
contact position can be mechanically transmitted to the interlocking module. It is
important whether the circuit breaker is mounted on the wall or on the floor. In one case
(wall mounting), the modification must be made to the side part; in the other (floor
mounting), the base support must be modified. The necessary modification is made in the
factory before delivery for the configuration ordered by the customer. This requires the
correct article number.
● Withdrawable breaker version: Here, the modules can be directly mounted on the guide
frame; modification of the circuit breaker side wall is not required.
Mutual mechanical interlocking
With the interlocking devices, two circuit breakers can be mutually interlocked. The
interlocking device only ever releases one circuit breaker at a time, thereby ensuring that
only the released circuit breaker can be operated. The other circuit breaker remains in the
safe OFF (O) position and is blocked by the interlocking mechanism.
Both horizontally and vertically oriented circuit breakers can be mutually mechanically
interlocked.
Maximum distances between circuit breakers:
● Horizontal: max. 2750 mm
● Vertical: max. 1000 mm
