Schaffner FN351-50-33 Industrial AC Line Filter

Schaffner FN351-50-33 is a three-phase, delta-connected EMI/EMC line filter designed for industrial inverters and motor drives, rated for 50 A and 440 VAC line-to-line (phase-to-phase) with a 1-stage, chassis-mount configuration. It uses a terminal-block termination and provides a phase-to-ground rating of 250 VAC, with a typical leakage current around 3.5 mA, making it suitable for clean power delivery in demanding environments. The enclosure measures about 200 x 150 x 65 mm and weighs roughly 1.6 kg, and it operates reliably from -25 C to 85 C. Note: This FN351-50-33 model is obsolete; TE Connectivity Schaffner lists FN351H-50-33 as the replacement.
