The FN258HV-75-34 is a three-phase (Delta) EMC/EMI line filter manufactured by TE Connectivity Schaffner. It features a 75 A current rating and a 690 VAC voltage rating, designed for operation between DC and 60 Hz. The unit utilizes chassis mount installation with terminal block termination. Physical dimensions are 300 mm in length, 80 mm in width, and 220 mm in height, with an operating temperature range of -25 C to +100 C. Leakage current is specified at 2.6 mA. It holds UL, CSA, and IEC/EN compliance certifications.
Verify the specific suffix '34' against official datasheets to confirm terminal configuration and certification status. Confirm availability as this component may be subject to discontinuation or supply constraints. Ensure the application environment matches the 690 VAC and 75 A ratings. Cross-reference physical dimensions for chassis compatibility before procurement.
Select this model when a two-stage EMI filter is required for three-phase Delta systems operating up to 690 VAC. The 75 A rating suits high-current industrial loads. Consider the slim profile for tight enclosures adjacent to drives. Verify that terminal block termination aligns with existing wiring infrastructure and that the 2.6 mA leakage current meets safety standards for the specific installation.
This component belongs to the FN258HV series, which provides high-voltage EMC filtering solutions. The series includes variants with different current ratings and terminal configurations. The FN258HV-75-34 specifically addresses the needs of robust industrial environments requiring reliable noise suppression for three-phase power lines.
