FN3270H-20-29

Overview

The Schaffner FN3270H-20-29 is a three-phase EMC/EMI line filter designed for industrial applications. It supports a rated current of 20 A and operates at voltages up to 480 V AC or DC, with a frequency of 60 Hz. The unit features chassis mounting and utilizes terminal block connections for input/output interfaces. This single-stage filter belongs to the FN 3270 series, which is characterized by an ultra-compact and lightweight design intended to minimize mounting space requirements within installations and cabinets.

Feature Summary

• Ultra-compact and lightweight construction requiring minimum mounting space
• Single-stage filtering architecture for efficient noise suppression
• Terminal block connection interface for secure electrical integration

Applications

• Industrial cabinet installations
• Three-phase power system noise suppression
• Equipment requiring compact EMC filtering solutions

Procurement Notes

Verify the specific voltage rating (480V AC/DC) and current capacity (20A) against your system requirements. Confirm that the chassis mounting style and terminal block termination are compatible with your enclosure design. Ensure the 60Hz frequency specification matches your operational environment. Cross-reference the manufacturer part number FN3270H-20-29 with official TE Connectivity/Schaffner documentation to confirm availability and technical validity before procurement.

Selection Notes

Select this component when space constraints are critical in three-phase power applications. The FN3270 series offers a balance of performance and physical footprint. Consider the terminal block interface if screw-down wiring is preferred over other connection methods. Verify that the 20A current rating provides sufficient margin for your load profile. Compare against other series if higher current or different mounting styles are required.

Part Context

This component is part of the Schaffner FN 3270 series, known for its high-performance EMC filtering in a small form factor. Manufactured by TE Connectivity / Schaffner, it serves as a power line filter for three-phase systems. The series is engineered to meet stringent electromagnetic compatibility standards while maintaining a lightweight profile suitable for dense packaging in industrial control panels and machinery.

Replacement Considerations

Consult official Schaffner or TE Connectivity substitution guides for verified equivalents. Generic replacements may not match the specific insertion loss characteristics or physical dimensions. Ensure any substitute maintains the 20A rating and 480V capability. Verify that the replacement also uses terminal block connections and chassis mounting to ensure mechanical compatibility.
