Each of the locking devices listed here is available in versions for the fixed-mounted and
withdrawable breaker versions.
●
Fixed-mounted breaker:
To mount the modules on a fixed-mounted 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.
