FN2520-20-08-C1111

Overview

The Schaffner FN2520-20-08-C1111 is a single-phase EMC/EMI power line filter designed for chassis mounting. It supports an input voltage of up to 277VAC and 400VDC, operating within a frequency range of DC to 60Hz. The unit handles a continuous current of 20A at +40°C. Key physical specifications include threaded post terminals (M4) for secure connection and a compact 1U rack-mount form factor. This configuration ensures effective noise suppression in space-constrained industrial environments while maintaining compliance with electrical safety standards.

Feature Summary

• Provides two-stage filtering architecture for enhanced electromagnetic interference suppression
• Features a space-saving 1U rack-mount design suitable for dense equipment layouts
• Utilizes threaded post terminals for robust mechanical and electrical connections

Applications

• Industrial machinery requiring high-current noise filtration
• Medical equipment needing stable power quality
• Telecommunications infrastructure systems

Procurement Notes

Verify the specific datasheet version for the FN2520-20-08-C1111 to confirm terminal torque specifications and mounting hole dimensions. Ensure compatibility with existing chassis cutouts due to the 1U form factor. Cross-reference the M4 threaded post requirements with available hardware. Confirm that the 20A rating aligns with the maximum load current of the target application under ambient temperature conditions.

Selection Notes

Select this model when a single-phase solution is required for currents up to 20A. The 277VAC and 400VDC ratings make it suitable for various international power standards. The threaded post interface offers higher mechanical stability compared to faston connectors. Consider the 1U height constraint during panel design to ensure adequate clearance for cable routing and heat dissipation.

Part Context

This component belongs to the FN2520 series of high-performance EMC/EMI IEC filters by Schaffner. The series is characterized by its ability to handle currents from 10A to 20A at +40°C. These filters are engineered for applications demanding significant noise attenuation in a compact footprint, bridging the gap between standard plug-in filters and larger custom solutions.

Replacement Considerations

Check for direct substitutes within the FN2520 series with different current or voltage ratings if operational parameters differ. Verify that alternative models maintain the same 1U rack-mount dimensions and M4 threaded post terminal style to ensure mechanical interchangeability without redesigning the chassis.
