6.6 Fuses and commutating reactors
6.6.1 Commutating reactors
Commutating reactors can be selected from Catalog DA93.1.
The line impedance including commutating reactors must be equivalent of between 4% and 10%
short-circuit voltage. Commutating reactors can be provided by the customer to limit commutating
voltage dips in the supply system (subject to local regulations).
6.6.2 Fuses
For technical data, configuring data and dimension drawings, please refer to Catalog DA94.1.
It is essential to use "UL-listed" or "UL-recognized" fuses for protection of devices in accordance
with UL standards.
