FN3268-7-44

Overview

The FN3268-7-44 is a three-phase EMC/RFI power line filter manufactured by TE Connectivity / Schaffner. It features a 7 A current rating and a 520 VAC voltage rating, designed for operation between 0 Hz and 60 Hz. The unit utilizes chassis mounting with terminal block termination and exhibits a leakage current of 2.5 mA. Physical dimensions are 160 mm in length, 40 mm in width, and 70 mm in height, weighing approximately 500 g. It operates within a temperature range of -25 °C to +100 °C and holds UL, CSA, and IEC/EN compliance certifications.

Feature Summary

• Provides electromagnetic interference suppression for three-phase power systems
• Designed for regeneration units and industrial power conditioning applications
• Utilizes a slim-line chassis mount form factor for space-constrained installations

Applications

• Regeneration units in industrial drive systems
• Three-phase power distribution panels requiring EMI filtering
• Industrial machinery with strict EMC compliance requirements

Procurement Notes

Verify the specific part number FN3268-7-44 against official TE Connectivity / Schaffner documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with existing chassis mounting hardware and terminal block wiring configurations. Cross-reference certification marks such as UL and CSA with local regulatory standards before integration into final equipment designs.

Selection Notes

Select this component when a three-phase filter with a 7 A continuous current rating is required for 520 VAC systems. Consider the 2.5 mA leakage current specification for sensitive ground references. Evaluate the thermal operating range up to +100 °C against the expected ambient conditions of the installation environment to ensure reliable performance without derating.

Part Context

This component belongs to the FN3268 series of power line filters from Schaffner. The series is characterized by compact dimensions suitable for panel mounting. The FN3268-7-44 specifically addresses low-current three-phase applications where minimal leakage current and high voltage tolerance are necessary for stable operation in noisy electrical environments.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Generic cross-references may not match the specific leakage current or dimensional constraints of the original design.
