Procurement Notes

Verify the specific suffix against official documentation, as variations exist within the FN3287 series regarding leakage current and voltage ratings. Confirm that the C33 designation aligns with the required terminal configuration and compliance standards for the target application before finalizing procurement.

Selection Notes

Select this component when a low-profile solution is required for three-phase noise suppression in drive environments. Ensure the 25 A current capacity matches the load requirements. Verify that the 530 VAC rating is compatible with the system's phase-to-phase voltage specifications.

Part Context

This model belongs to the FN3287 series, which provides high-performance electromagnetic interference suppression. The series is characterized by its compact physical dimensions relative to its electrical capacity, facilitating dense packaging in control cabinets and drive assemblies.

Replacement Considerations

Cross-reference part numbers such as FN3287-25-33-C21-R65 or FN3287-25-33-C33-R65 variants if different terminal styles or leakage current limits are required. Verify mechanical fit and electrical ratings before substituting.
