Key Parameters

Substitute Part Grouping Explanation

The FN3258-7-44 qualifies as a direct substitute for the FN3258-7-45 based on the following critical parameters:

• Three-phase delta filter topology with identical single-stage configuration
• Matching current rating of 7 A
• Identical voltage specifications: 277 V phase-to-ground/neutral and 480 V phase-to-phase
• Identical frequency operating range: DC ~ 60Hz
• Matching mechanical interface: chassis mount with terminal block termination
• Equivalent operating temperature range: -25°C ~ 100°C
• Identical regulatory approvals: CSA, ENEC, UR certifications

Both parts belong to the FN 3258 series and share the same functional design. The primary distinction is product status and packaging configuration.
