FN258L-7-07

Overview

The Schaffner FN258L-7-07 is a three-phase EMC/RFI power line filter designed for chassis mounting. It features a low-leakage configuration with a rated current of 7 A and operates at voltages up to 480 VAC. The unit utilizes wire termination and supports frequencies from 0 Hz to 60 Hz. Key electrical specifications include a leakage current of 2 mA. Physical dimensions are 126 mm in height, 225 mm in length, and 50 mm in width. The component complies with UL, CSA, and IEC/EN standards and functions within an operating temperature range of -25°C to +100°C.

Feature Summary

• Low-leakage design suitable for sensitive equipment
• Three-phase EMC/RFI filtering capability
• Chassis mount installation style

Applications

• Three-phase inverters
• Power drive systems
• Industrial machinery requiring low leakage current

Procurement Notes

Verify the specific part number against official TE Connectivity / Schaffner documentation before procurement. Confirm that the low-leakage variant (indicated by 'L') matches system requirements, as standard versions may differ. Check for end-of-life notifications or discontinuance notices, as availability may be restricted. Ensure compliance with local safety certifications such as UL and CSA for the intended deployment region.

Selection Notes

Select this component when a three-phase filter with minimal leakage current is required for chassis-mounted applications. The 7 A rating suits moderate power loads. Verify that the wire termination style aligns with existing wiring harnesses. Consider the physical dimensions to ensure adequate space within the enclosure. Confirm that the operating temperature range meets environmental conditions.

Part Context

The FN258L series belongs to the broader FN258 family of three-phase filters manufactured by Schaffner. These filters are engineered for use in industrial environments involving inverters and power drive systems. The 'L' suffix typically denotes a low-leakage variant, distinguishing it from standard models within the same series. This product line provides industry-standard EMC solutions for reducing electromagnetic interference in AC power lines.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Cross-referencing with distributors may yield alternatives, but verify technical equivalence regarding leakage current and phase configuration.
