FN3258H-16-45

Overview

The Schaffner FN3258H-16-45 is a three-phase ultra-compact EMC/RFI line filter designed for chassis mounting. It operates within a frequency range of DC to 60 Hz and supports a rated voltage of 440 VAC with a current rating of 16 A. The component utilizes terminal block connections and exhibits a leakage current of 33 mA. Official documentation classifies this specific part number as obsolete, indicating it is no longer manufactured by TE Connectivity / Schaffner.

Feature Summary

• Three-phase configuration for industrial power line noise suppression
• Ultra-compact physical design optimized for space-constrained chassis installations
• Terminal block termination method for secure wiring integration

Applications

• Industrial machinery power conditioning
• Manufacturing equipment EMC compliance
• Power distribution units requiring three-phase filtering

Procurement Notes

This component is officially listed as obsolete and no longer in production. Sourcing new original parts from authorized distributors is not possible. Verification of authenticity is critical if purchasing from secondary markets, as availability is limited to existing stock or surplus channels. Buyers must confirm the exact condition and origin of any available units before acquisition.

Selection Notes

Engineers should evaluate alternative models within the FN3258 series that remain in active production. Selection criteria must align with the original electrical requirements, specifically the 16 A current capacity and 440 VAC voltage rating. Compatibility with existing chassis mounting structures and terminal block interfaces should be verified when choosing a replacement to ensure seamless integration without mechanical modifications.

Part Context

The FN3258H-16-45 belongs to the Schaffner FN 3258 family of three-phase power line filters. This series is characterized by its ultra-compact form factor and high performance in suppressing electromagnetic interference. The manufacturer, TE Connectivity / Schaffner, produces these components for global industrial applications, though specific variants may reach end-of-life status over time.

Replacement Considerations

Consult official Schaffner databases for current equivalents. Potential substitutes include other FN3258 variants with matching 16 A ratings and terminal block terminations. Verify that replacement models maintain compatibility with 440 VAC systems and chassis mounting constraints.
