FN3280H-25-33-R69

Overview

The FN3280H-25-33-R69 is a three-phase power line filter manufactured by Schaffner EMC Inc. It features a rated current of 25 A and supports voltages up to 480 V AC. The unit provides common mode attenuation of 100 dB at 1 MHz and differential mode attenuation of 60 dB at 100 kHz. Designed for industrial environments, it utilizes a robust metal housing with integrated mounting brackets. The filter includes built-in X and Y capacitors along with common mode chokes to suppress electromagnetic interference effectively across the specified frequency range.

Feature Summary

• Integrated EMI suppression using combined X, Y capacitors and common mode chokes
• Robust metal enclosure designed for secure panel mounting in industrial settings
• High attenuation performance for both common and differential mode noise

Applications

• Industrial motor drives and variable frequency drives
• Power supply units requiring strict EMC compliance
• Medical equipment with sensitive electronic components

Procurement Notes

Verify the specific part number suffix against official Schaffner documentation to ensure correct terminal configuration and mounting style. Confirm voltage ratings and current capacity match the target application requirements before procurement. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this model based on the required 25 A current rating and 480 V AC operating voltage. Ensure the installation space accommodates the physical dimensions of the metal housing. Verify that the mounting bracket orientation aligns with the available panel space in the equipment design.

Part Context

This component belongs to the FN3280 series of three-phase filters from Schaffner. The series is engineered for high-current applications in demanding industrial environments. The H variant typically denotes specific internal construction or enhanced performance characteristics compared to standard models within the same family.

Replacement Considerations

Consult Schaffner's official cross-reference guides for verified substitutes. Ensure any replacement matches the 25 A rating, 480 V AC voltage, and physical footprint. Verify that alternative models provide equivalent attenuation levels at critical frequencies.
