FN258L-16-29

Overview

The Schaffner FN258L-16-29 is a three-phase EMC/RFI power line filter designed for industrial applications. It features a rated voltage of 480 VAC and a current rating of 16 A, with an operating frequency range of 0 Hz to 60 Hz. The unit utilizes terminal block termination and chassis mounting. Key electrical specifications include a maximum leakage current of 0.8 mA and a high potential test voltage of 2100 V. Physical dimensions are 275 mm in length, 55 mm in width, and 142 mm in height. It operates within a temperature range of -25 °C to +100 °C.

Feature Summary

• Provides robust electromagnetic interference mitigation for three-phase power systems
• Engineered for low leakage current applications to enhance safety
• Designed for chassis mounting with terminal block connections

Applications

• Industrial automation systems
• Three-phase power drive systems
• Climate control equipment

Procurement Notes

Verify the specific suffix 'L' against official datasheets to confirm it denotes the low-leakage variant, as standard FN258 models may differ significantly in leakage specifications. Confirm that the terminal block interface matches your existing wiring infrastructure. Ensure the chassis mount footprint aligns with your enclosure design constraints before finalizing procurement.

Selection Notes

Select this component when low leakage current is critical for personnel safety or sensitive equipment operation in three-phase environments. Compare the 16 A rating against peak load requirements to ensure adequate headroom. Verify that the 480 VAC rating matches the nominal system voltage. Consider the physical dimensions if space is constrained within the installation panel.

Part Context

This component belongs to the Schaffner FN258 series, which provides industry-standard EMC solutions for three-phase inverters and power drive systems. The series is recognized for mitigating electromagnetic interference in industrial settings. The FN258L variant specifically addresses applications requiring reduced leakage current compared to standard models in the same family.

Replacement Considerations

Public documentation indicates that the related model FN258-16-29 is obsolete. Verify if the non-L version meets leakage requirements if substituting. No direct public substitute part numbers are confirmed for the specific FN258L-16-29 configuration.
