FN3288IT-25-33-C34-R60

Overview

The FN3288IT-25-33-C34-R60 is a three-phase EMC/RFI power line filter from the Schaffner FN3288 series. It features a slim design with two-stage filtering configuration, rated for 25 A current and operating at frequencies from DC to 60 Hz. The unit supports voltage ratings between 305 VAC and 760 VAC, with a maximum leakage current of 5.9 mA. It utilizes chassis mounting and terminal block termination for secure installation in industrial environments.

Feature Summary

• Two-stage filtering architecture for enhanced noise attenuation
• Slim form factor designed for space-constrained enclosures
• Terminal block termination for robust electrical connections

Applications

• Industrial machinery power supply conditioning
• Three-phase motor drive systems
• Medical equipment power input stages

Procurement Notes

Verify exact voltage compatibility within the 305–760 VAC range against your specific system requirements before integration. Confirm that the 5.9 mA leakage current aligns with safety standards applicable to your end-use application. Ensure chassis mounting provisions match the physical dimensions of the enclosure. Cross-reference the terminal block specifications with existing wiring infrastructure to guarantee proper connection integrity.

Selection Notes

Select this model when high-density packaging is required alongside significant current handling capabilities. The two-stage design offers superior performance compared to single-stage alternatives in noisy environments. Consider the slim profile if vertical or horizontal space is limited within the control cabinet. Verify that the terminal block interface suits the available cable gauge and termination tools for the specific installation site.

Part Context

This component belongs to the FN3288 series, which focuses on compact three-phase filtering solutions. The IT suffix typically denotes specific insulation or construction variations within the broader product family. Schaffner designs these units to meet stringent international EMC standards, providing reliable interference suppression for sensitive electronic loads connected to three-phase power networks.

Replacement Considerations

Direct substitutes include other models within the FN3288 series with matching 25 A ratings and similar voltage specifications. Verify that any replacement maintains the same two-stage topology and terminal block termination style to ensure mechanical and electrical compatibility without redesigning the mounting structure.
