Consider the following criteria when using mains chokes:

ƒ

Mains chokes are always required if all interconnected devices are operated with
rated current and speed.

ƒ

Mains chokes are not required if the power of the entire network is less than 50 % of
the added continuous powers of all interconnected devices (= standard case).

ƒ

The use of mains chokes for complying with the EMC category C3 has to be assessed
separately (
