FN3288-40-33-C21-R65

Overview

The FN3288-40-33-C21-R65 is a three-phase EMC/RFI power line filter from the Schaffner FN3288 series. It features a voltage rating of 530 VAC and a current rating of 40 A. The unit utilizes chassis mount installation with terminal block termination. Key electrical specifications include a leakage current of 0.4 mA and an operating frequency range of 0 Hz to 60 Hz. Physical dimensions are approximately 226 mm in length, 65 mm in width, and 180 mm in height, with a weight of 2.5 kg. It complies with UL 60939-3 and IEC 60939-3 standards.

Feature Summary

• Provides effective electromagnetic interference suppression for three-phase power systems
• Designed for robust chassis mounting using terminal block connections
• Operates reliably within a wide temperature range from -40°C to +100°C

Applications

• Industrial machinery power conditioning
• Three-phase motor drive input filtering
• Heavy-duty manufacturing equipment EMI reduction

Procurement Notes

Verify the specific part number suffix against official TE Connectivity/Schaffner documentation to ensure correct terminal configuration and compliance certifications. Confirm that the required current and voltage ratings match the application load precisely. Check for any specific regional regulatory approvals required for the deployment site before finalizing procurement orders.

Selection Notes

Select this model when a high-current three-phase filter is required for chassis-mounted applications. Ensure the available panel space accommodates the specified physical dimensions. Verify that the terminal block interface matches the existing wiring harness or busbar setup. Consider thermal management requirements given the maximum operating temperature limit of 100°C.

Part Context

This component belongs to the FN3288 series of slim-line power line filters manufactured by Schaffner, now part of TE Connectivity. The series is engineered for industrial environments requiring compact yet high-performance EMI suppression. These filters are designed to meet stringent international safety and EMC standards for three-phase AC power networks.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Ensure any replacement maintains identical current ratings, voltage limits, and physical mounting footprint. Verify that alternative models offer comparable attenuation characteristics and comply with the same regulatory standards.
