FN3258H-7-45

Overview

The Schaffner FN3258H-7-45 is a three-phase delta EMC/EMI line filter rated for 7 A at DC to 60 Hz. It features chassis mounting and terminal block termination. The unit has a leakage current of 33 mA and operates within a temperature range of -25°C to +100°C. This single-stage filter is designed for power line conditioning in industrial environments.

Feature Summary

• Provides electromagnetic interference suppression for three-phase delta configurations
• Utilizes terminal block connections for secure electrical integration
• Engineered for chassis mounting to facilitate panel installation

Applications

• Industrial machinery power supply filtering
• Three-phase motor drive input protection
• Power distribution unit noise reduction

Procurement Notes

Verify the specific suffix '45' against official datasheets to confirm terminal type and leakage current specifications. Ensure the application voltage does not exceed the component's rated limits. Confirm availability status as this part may have restricted supply conditions compared to standard series items.

Selection Notes

Select this model when a compact three-phase delta filter with low current rating is required. Compare leakage current requirements against sensitive equipment standards. Verify that the terminal block interface matches the existing wiring harness or busbar configuration for seamless integration.

Part Context

This component belongs to the FN3258 series, which offers ultra-compact three-phase filtering solutions. The 'H' variant typically denotes specific construction or performance enhancements within the family. It serves as a specialized solution for applications requiring precise current handling and minimal footprint.

Replacement Considerations

Check for direct substitutes such as the FN3258-7-44 if pinout compatibility is critical. Verify that alternative models maintain the same three-phase delta configuration and current rating to ensure circuit integrity.
