FN3256H-120-35

Overview

The FN3256H-120-35 is a three-phase and neutral power line filter manufactured by Schaffner EMC Inc. It features a chassis mount design with terminal block termination for secure electrical connections. The unit supports a maximum voltage of 480V AC at 60Hz and handles a rated current of 120A. Physical dimensions are 110mm in length, 110mm in depth, and 70mm in height. It operates within a temperature range of -25°C to +100°C, with a leakage current of 1mA and power loss of 2.7W.

Feature Summary

Provides electromagnetic interference suppression for three-phase systems
Utilizes chassis mounting for stable industrial installation
Employs terminal block connections for reliable wiring

Applications

Industrial machinery power input stages
Three-phase motor drive protection circuits
Heavy-duty equipment EMI mitigation

Procurement Notes

Verify the specific voltage rating requirement against the datasheet, as sources indicate both 480V AC and 520V AC ratings for this series. Confirm that the terminal block interface matches existing panel layouts. Ensure the 120A current capacity aligns with the system load profile. Check for updated compliance certifications required for the target market before finalizing procurement orders.

Selection Notes

Select this model when high-current three-phase filtering is necessary for chassis-mounted applications. Compare thermal performance and physical footprint against alternative filters if space constraints exist. Verify compatibility with the specific terminal block configuration used in the assembly. Consider the operating temperature range limits for enclosed installations.

Part Context
