FN2020-20-06

Overview

The Schaffner FN2020-20-06 is a single-phase EMC/EMI power line filter designed for chassis mounting. It features a metal case to ensure optimum earth connection and high-frequency performance. The unit supports a current rating of 20 A at AC voltages up to 250 V. Operating within a frequency range of DC to 400 Hz, it utilizes faston quick-connect terminals for input and output termination. The design allows space for circuit stages to attenuate noise effectively.

Feature Summary

• Metal housing provides robust earth connection and enhanced high-frequency attenuation capabilities
• Single-stage configuration optimized for general-purpose industrial electromagnetic interference suppression
• Quick-connect terminal style facilitates rapid installation and secure electrical interfacing

Applications

• General-purpose industrial equipment protection
• Power supply input filtering
