FN258P-42-33

Overview

The Schaffner FN258P-42-33 is a three-phase EMC/RFI power line filter designed for chassis mounting. It features a terminal block termination style and supports a rated current of 42 A with a voltage rating of 480 VAC. The unit operates within a temperature range of -25 °C to +100 °C and has a leakage current of 3 mA. Physical dimensions are 300 mm in length, 70 mm in width, and 185 mm in height, weighing approximately 3 kg. It holds UL, CSA, and IEC/EN compliance certifications.

Feature Summary

• Provides electromagnetic interference suppression for three-phase power systems
• Utilizes a robust chassis mount design for secure installation
• Incorporates terminal block connections for straightforward wiring

Applications

• Industrial machinery power distribution
• Three-phase motor drive systems
• Commercial building electrical infrastructure

Procurement Notes

Verify the specific suffix 'P' against official TE Connectivity or Schaffner documentation to confirm it denotes the standard 480 VAC variant rather than high-voltage (HV) or insulated terminal (IT) versions. Confirm current availability status as similar models in this series may be subject to lifecycle changes. Ensure the terminal block configuration matches existing panel layouts before procurement.

Selection Notes

Select this model when a 42 A capacity is required for three-phase applications operating at 480 VAC. The chassis mount form factor suits enclosed equipment installations where space efficiency is prioritized. Verify that the 3 mA leakage current meets safety standards for the specific application environment. Compare physical dimensions against available mounting space to ensure compatibility.
