Mfr. Schaffner, type FN258
3-phase mains filter in metal housing for chassis mounting. Supplied with 2 separate choke coil steps for each phase. Therefore the FN258 provides good attenuation of both symmetric and asymmetric interferences. No connection of the zero-conductor. Connection by fixed cables. Adapted for lengths of cables for up to 50 m. Type with max input voltage 690 V is offered on demand.
Approvals: CSA, Enec, UL (rec).
