FN258L-7-29

Overview

The FN258L-7-29 is a three-phase EMC/RFI power line filter from the Schaffner FN258 series, manufactured by TE Connectivity. It features a chassis mount design with terminal block termination for secure electrical connections. The unit is rated for 480 VAC and supports a continuous current of 7 A within an operating frequency range of 0 Hz to 60 Hz. Key electrical specifications include a maximum leakage current of 100 uA. The physical dimensions are 205 mm in length, 50 mm in width, and 126 mm in height, with an operational temperature range spanning from -25°C to +100°C.

Feature Summary

• Provides two-stage attenuation for effective electromagnetic interference suppression in three-phase systems
• Utilizes a robust chassis mount construction suitable for industrial panel integration
• Incorporates terminal block connections to facilitate straightforward wiring and maintenance

Applications

• Industrial machinery requiring three-phase power conditioning
• Medical equipment demanding strict electromagnetic compatibility
