Procurement Notes
Verify the specific suffix 'H' against official Astrodyne TDI documentation to confirm terminal configuration and mounting details. Ensure the application environment matches the 480 V and 30 A ratings. Cross-reference certification marks such as UL and TUV with current regulatory requirements for the target installation region before procurement.
Selection Notes
Select this model when dual-stage attenuation is required for three-phase delta networks. Confirm that the 10-32 threaded post interface aligns with existing busbar or cable termination hardware. Validate that the 3500 VDC hipot rating meets insulation coordination requirements for the specific power system voltage levels.
Part Context
This component belongs to the 3H series of power line filters from Astrodyne TDI. The series specializes in EMI/EMC solutions for demanding markets including aerospace, industrial, medical, military, and semiconductor sectors. The manufacturer focuses on custom and standard AC/DC power supplies and filters for global applications.
Replacement Considerations
Consult official Astrodyne TDI substitution guides for direct equivalents. Verify that any alternative part maintains the same three-phase delta topology, 30 A current rating, and 480 V operating voltage. Ensure mechanical mounting compatibility with the 10-32 threaded post interface.
