FN3256H-25-33

Overview

The Schaffner FN3256H-25-33 is a three-phase and neutral power line filter designed for industrial applications. It features a rated current of 25 A and a voltage rating of 520 VAC, operating within a frequency range of 0 Hz to 60 Hz. The unit utilizes chassis mount installation with terminal block termination. Key electrical specifications include a leakage current of 600 uA. Physical dimensions are 180 mm in length and 85 mm in height. It supports an operating temperature range from -25°C to +100°C and holds UL, CSA, and IEC/EN compliance certifications.

Feature Summary

• Provides electromagnetic interference suppression for three-phase and neutral circuits
• Designed for compact integration into industrial machinery enclosures
• Utilizes terminal block connections for secure wiring

Applications

• Industrial equipment EMC filtering
• Machinery power conditioning
• Three-phase power supply noise reduction

Procurement Notes

Verify the specific suffix codes against official TE Connectivity documentation to ensure correct pinout and certification status. Confirm that the 520 VAC rating aligns with your system's nominal voltage. Check for updated compliance certificates such as UL and IEC/EN before finalizing procurement. Ensure chassis mounting provisions match your enclosure design constraints.

Selection Notes

Select this model when a three-phase plus neutral configuration is required for 25 A loads. Consider the 600 uA leakage current limit if sensitive downstream equipment is present. Evaluate the physical footprint of 180 mm by 85 mm against available panel space. Verify that terminal block termination suits your existing cabling infrastructure.
