FN3258-30-33

Overview

The Schaffner FN3258-30-33 is a three-phase EMC/RFI power line filter designed for chassis mounting. It supports a rated voltage of 480 VAC and a continuous current of 30 A at 60 Hz. The unit features terminal block termination and exhibits a leakage current of 4.3 mA. Physical dimensions are 240 mm in length, 50 mm in width, and 85 mm in height, with an operating temperature range from -25°C to +100°C. Certified by UL, CSA, and IEC/EN standards.

Feature Summary

• Ultra-compact design optimized for space-constrained motor drive applications
• Single-stage filtering architecture for efficient noise suppression
• Terminal block connection method for secure electrical interfacing

Applications

• Motor drive systems requiring compact EMI mitigation
• Industrial machinery power supply lines
• Three-phase equipment installation panels

Procurement Notes

Verify the specific part number against official TE Connectivity / Schaffner documentation to confirm compatibility with your system requirements. Ensure that the 480 VAC rating and 30 A current capacity align with your operational parameters. Check for required certifications such as UL or CSA depending on regional compliance needs. Confirm terminal block specifications match your wiring infrastructure before procurement.

Selection Notes

Select this component when space efficiency is critical for three-phase EMC filtering. The ultra-compact form factor distinguishes it from standard filters in its class. Consider the 4.3 mA leakage current if sensitive ground references are present. Verify that the chassis mount style fits your enclosure layout and thermal management strategy within the specified temperature range.

Part Context

This model belongs to the FN3258 series, characterized by ultra-compact construction for three-phase applications. It serves as a specialized solution for environments where physical footprint constraints limit the use of larger filtration units. The series maintains consistent terminal block connectivity across variants.

Replacement Considerations

Consult official manufacturer substitution lists for verified equivalents. Generic cross-references may not preserve the ultra-compact dimensions or specific leakage characteristics required for tight fitment.
