FN3258H-100-35

Overview

The Schaffner FN3258H-100-35 is a three-phase EMC/RFI power line filter designed for ultra-compact installation. It features a rated current of 100 A and operates at frequencies from 0 Hz to 60 Hz with a voltage rating of 480 VAC. The unit utilizes terminal block termination and chassis mounting. Key electrical specifications include a leakage current of 4.7 mA and a maximum operating temperature of +100°C. Physical dimensions are approximately 240 mm in length, 150 mm in height, and 50 mm in width, weighing 1.4 kg.

Feature Summary

• Ultra-compact design optimized for space-constrained industrial enclosures
• High current capacity suitable for demanding three-phase applications
• Low leakage current configuration for enhanced safety compliance

Applications

• Industrial machinery power conditioning
• Factory automation equipment filtering
• Servo drive input protection

Procurement Notes

Verify the specific suffix 'H' against official datasheets to confirm exact leakage current and dimensional tolerances, as variations exist within the FN3258 series. Ensure terminal block compatibility with existing busbar or cable configurations. Confirm that the 100 A continuous current rating aligns with the actual load profile and ambient temperature conditions to prevent thermal derating issues during operation.

Selection Notes

Select this model when high current handling is required in a minimal footprint. Compare leakage current requirements against sensitive downstream equipment limits. Verify that the chassis mounting style fits the available panel space. Consider the operating temperature range if the installation environment exceeds standard ambient conditions.

Part Context

This component belongs to the Schaffner FN3258 series, which focuses on ultra-compact three-phase filtering solutions. The series is engineered for industrial environments where space efficiency and high performance are critical. It complements other models in the lineup by offering higher current ratings in similar physical constraints.

Replacement Considerations

Direct substitutes may include other FN3258 variants with adjusted current ratings, such as FN3258-75-34, provided the lower current capacity meets system requirements. Cross-series replacements like FN3270H-35-33 are unsuitable due to significantly lower current ratings.
