Overview
The Schaffner FN2450F-20-61 is a single-phase EMC/EMI power line filter designed for chassis mounting with screw termination. It features a 20 A current rating and operates at voltages up to 250 VAC within a frequency range of 0 Hz to 400 Hz. The device incorporates very low leakage current characteristics, specifically rated at 660 µA, ensuring safety compliance in sensitive applications. Constructed as a single-stage filter, it provides effective attenuation for electromagnetic interference while maintaining robust electrical performance under standard industrial operating conditions.
Feature Summary
- Single-phase EMC/EMI filtering architecture
- Chassis mount installation with screw terminals
- Low leakage current design for safety compliance
Applications
- Industrial motor control cabinets
- Medical equipment power supplies
- General industrial machinery
Procurement Notes
Verify the specific part number suffix against official TE Connectivity / Schaffner documentation to confirm exact leakage current ratings and certification status. Ensure that the chassis mounting dimensions and terminal spacing match the intended enclosure design. Confirm that the 20 A continuous current rating aligns with the system's maximum load requirements without derating issues.
Selection Notes
Select this component when a single-phase solution with low leakage current is required for 250 VAC systems operating up to 400 Hz. The chassis mount style necessitates adequate panel space and thermal management considerations. Verify that the screw termination type is compatible with the available wiring infrastructure and torque specifications for reliable long-term connection integrity.
Part Context
This component belongs to the Schaffner FN2450 series, which offers single-stage EMC/EMI filtration solutions. The series is characterized by compact dimensions and high reliability for industrial environments. The FN2450F variant specifically denotes the configuration associated with the 20 A rating and low leakage specifications within the broader product family.
Replacement Considerations
Consult official cross-reference lists for direct substitutes. Generic replacements may not maintain the specific 660 µA leakage current limit or the 400 Hz operational capability. Verify mechanical fitment and terminal compatibility before substitution.
