FN258P-42-07

Overview

The Schaffner FN258P-42-07 is a three-phase power line filter designed for industrial electromagnetic compatibility. It supports a rated current of 42 A and operates at voltages up to 480 VAC within the 0 Hz to 60 Hz frequency range. The unit features chassis mounting with wire termination and exhibits a leakage current of 3 mA. Physical dimensions are 300 mm in length, 70 mm in width, and 185 mm in height, weighing approximately 2.531 kg. It complies with UL, CSA, and IEC/EN standards and functions between -25°C and +100°C.

Feature Summary

• Provides effective attenuation of electromagnetic interference across three-phase power lines
• Engineered for robust chassis mounting applications requiring secure wire connections
• Complies with international safety and electromagnetic compatibility certification requirements

Applications

• Industrial machinery power supply conditioning
• Three-phase motor drive input filtering
• Heavy-duty manufacturing equipment EMC compliance

Procurement Notes

Verify component authenticity through authorized TE Connectivity or Schaffner channels. Confirm that the specific suffix matches the required terminal configuration and certification marks for your region. Request official test reports to validate performance against specified leakage and attenuation parameters before integration into critical systems.

Selection Notes

Select this model when three-phase filtering is required for currents near 42 A at 480 VAC. Ensure chassis mounting space accommodates the 300x70x185 mm footprint. Verify that wire termination suits the existing cable gauge. Consider thermal derating if ambient temperatures approach the upper operational limit of 100°C.
