Three-phase mains filter

Three-phase mains filter against interference impulses and surge voltages

REO three-phase mains filters for interference suppression in accordance with EN 55011 and EN 618003

Three-phase mains filters filter interferences in both directions – from the consumer to the network and from the network to the consumer. Typical applications are for example frequency inverters, wind turbines or power supplies.
