Different versions exist depending on the input current:

• Units ? 800 A include a main control switch with fuse switch disconnector
• Units > 800 A include a fixed-mounted circuit breaker (a withdrawable circuit breaker is optionally possible)

When Line Connection Modules are ordered, the type of Line Module used must be specified:

• for Basic Line Modules: Option L43
• for Smart Line Modules: Option L44
• for Active Line Modules: Option L42

When using a Basic Line Modules, a reactor is included in the scope of delivery, and when required, can be deselected (option L22).
For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

Option main contactor, order code L13

Example of connection of a Line Connection Module for units > 800 A, < 2000 A
to connect to the Basic Line Modules, option L43

For input currents ? 2000 A, additional options are available:

• Grounding switch upstream of main circuit breaker: Option L46
• Current transformer upstream of main circuit breaker: Option L41
• Grounding switch downstream of main circuit breaker: Option L47

When Basic Line Modules that are fed via a common Line Connection Module are connected in parallel, line reactors are generally required. These are installed in the Line Connection Module.
