Schaffner FN 258L-30-07 Inverter Line Filter Assembly

Schaffner FN258L-30-07 is a three‑phase inverter line filter from Schaffner (now TE Connectivity Schaffner) designed to suppress EMI on inverter and power‑drive lines. This 30 A, delta‑connected, two‑stage line filter is a chassis‑mounted assembly with a terminal‑block input/output. It accepts three‑phase input up to 480 V line‑to‑line and 277 V line‑to‑ground, with operating frequency range listed from DC to 60 Hz, making it suitable for inverter drives and motor‑control applications. The unit is rated for service from −25 °C to +100 °C and carries CSA, ENEC, and UR approvals. As part of the FN258 family, the FN258L-30-07 is now obsolete and no longer manufactured; distributors commonly point to newer substitutes such as FN3288‑25‑33‑C26‑R65 for updated designs.
