Availability of option
This option is available for the following S120 Cabinet Modules:
● Line Connection Modules, only with option L43 (for Basic Line Modules)

If the Basic Line Module or Smart Line Module is supplied via a separate transformer, or if
the supply system has a sufficiently low supply short-circuit power, the standard line reactor
can be omitted.

conjunction with the Basic Line Module (option L43).
The Smart Line Module with option L22 is supplied without a standard line reactor.
