Procurement Notes

Verify the specific part number against official Schaffner or TE Connectivity documentation to confirm chassis mount configuration and current ratings. Ensure compatibility with existing panel cutouts and thermal management requirements. Cross-reference certification marks such as CSA, ENEC, and UR with local regulatory needs. Confirm lead times through authorized distributors as manufacturing integration into TE Connectivity may affect availability.

Selection Notes

Select this model when high-current three-phase filtering is required for chassis-mounted installations. Consider the 280A rating and single-stage design for space-constrained industrial panels. Verify voltage and frequency specifications match the target power system. Evaluate thermal dissipation capabilities given the wide operating temperature range. Ensure mechanical mounting dimensions align with the equipment enclosure design.
