FN354-25-47

Overview

The FN354-25-47 is a three-phase and neutral power line filter manufactured by TE Connectivity / Schaffner. It features a chassis mount design with terminal block termination. The unit is rated for 25 A current and 440 VAC voltage, operating within a frequency range of 0 Hz to 60 Hz. Key electrical specifications include a maximum leakage current of 200 uA and an operating temperature range from -25 C to +100 C. The component weighs 4.7 kg and holds UL, CSA, and IEC/EN compliance certifications.

Feature Summary

• Provides electromagnetic interference suppression for three-phase power systems
• Utilizes a robust chassis mount construction for secure installation
• Employs terminal block connections for straightforward wiring integration

Applications

• Industrial motor drive systems requiring EMI filtering
• Three-phase power distribution units
• Heavy machinery control panels

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before initiating procurement. Confirm that the terminal block interface and chassis mounting dimensions align with existing infrastructure. Ensure the 25 A rating and 440 VAC specification meet the target application requirements. Check for available substitute models if long-term supply stability is a priority.

Selection Notes

Select this model only when a three-phase configuration with neutral connection is explicitly required. The 25 A current capacity must match the load profile without exceeding thermal limits. Verify that the chassis mount style fits the enclosure constraints. Consider the NRND status when planning for future maintenance or system upgrades.

Part Context

This component belongs to the FN354 series of standard performance filters designed for industrial environments. It addresses noise reduction in three-phase circuits where neutral line filtering is necessary. The series is known for high reliability in demanding power conditioning applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative models from the same manufacturer should be evaluated for compatibility.
