Procurement Notes

Verify the specific part number against official TE Connectivity or Schaffner documentation to confirm compatibility with your system requirements. Ensure that the terminal block interface matches your wiring infrastructure. Cross-reference certification marks such as UL, CSA, and IEC/EN with local regulatory standards before integration. Confirm thermal management capabilities align with the specified operating temperature range.

Selection Notes

Select this component when a three-phase filter is required for 480 VAC applications with a continuous current rating near 55 A. The terminal block termination style dictates the connection method, differing from screw or stud options. Consider the physical dimensions and chassis mounting requirements during mechanical design. Evaluate leakage current specifications against safety grounding constraints in sensitive environments.
