Procurement Notes

Verify the specific suffix against official TE Connectivity documentation to confirm exact termination style and certification variants. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the received component matches the specified 64 A rating and 520 VAC voltage class for the intended application environment.

Selection Notes

Select this model when a three-phase filter with a 64 A continuous current capacity is required. The 520 VAC rating suits standard industrial distribution voltages. Consider the chassis mount form factor and terminal block interface for panel integration. Verify that the physical dimensions fit the available enclosure space and that the thermal operating range meets site conditions.

Part Context

This component belongs to the Schaffner FN3256 series, which comprises compact line filters designed for industrial applications. The series offers various current ratings and configurations to address different power requirements.
