Line reactor

A line reactor protects the inverter when connected to dirty line supplies. A line reactor
supports the overvoltage protection, smooths the harmonics in the line supply and buffers
commutation dips.
The line reactors for Power Modules, frame sizes FSA ... FSC, are suitable for base
mounting as well as for installation next to the inverter.
Note
When do you require a line reactor?
Without line reactor, the inverter is suitable for line supplies with Uk ≥ 1 %. For Uk < 1 %,
you must use a line reactor.
Mounting position
Clearances to other devices
For a line reactor, a minimum clearance to other devices must be maintained on all sides.
