FN3258H-130-35

Overview

The Schaffner FN3258H-130-35 is a three-phase EMC/RFI power line filter designed for high-current industrial applications. It features a rated current of 130 A and a voltage rating of 480 VAC to 520 VAC, operating within a frequency range of 0 Hz to 60 Hz. The unit utilizes terminal block connections for secure wiring and supports chassis mounting. Key electrical specifications include a leakage current of approximately 4.7 mA and a maximum power loss of 34.5 W. Physical dimensions are 240 mm in length, 90 mm in width, and 150 mm in height, with an operating temperature range from -25°C to +100°C.

Feature Summary

• Ultra-compact and slim design optimized for minimal installation space constraints
• Incorporates safety terminal blocks for rapid and reliable connection methods
• Provides effective attenuation of conducted electromagnetic interference in three-phase systems

Applications

• Motor drive and variable speed drive input stages
• Industrial machinery requiring strict EMI compliance
• Power supply units for sensitive electronic equipment

Procurement Notes

Verify the specific voltage rating requirement (480 VAC vs 520 VAC) against your system specifications before ordering. Confirm that the terminal block interface matches your existing cabling infrastructure. Ensure the chassis mounting holes align with your enclosure design. Check for updated certification status such as UL, CSA, or IEC/EN if required by your regional regulations.

Selection Notes

Select this model when high current capacity up to 130 A is required alongside stringent size limitations. The FN3258H series is suitable where standard filters exceed available depth or height constraints. Consider the thermal performance and power loss characteristics if the installation environment has limited airflow. Ensure the leakage current specification meets the safety requirements of the final application.

Part Context

This component belongs to the Schaffner FN3258 series, which specializes in ultra-compact three-phase filtering solutions. The series is engineered to address space-constrained environments in industrial automation and power electronics. It serves as a critical interface for mitigating noise generated by switching devices while maintaining signal integrity for connected loads.

Replacement Considerations

Direct substitutes may include other models within the FN3258 series with adjusted current ratings, such as FN3258-100-35, provided the lower current capacity meets system demands. Verify dimensional compatibility and terminal block configuration when considering alternative part numbers.
