The Molex 430452406 is a 24-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power interconnects in automotive, industrial, medical, and telecom equipment.
The 8 A per circuit current rating, combined with the 60.0 µinch tin mating finish, tells you this is a power-duty header.
Against the 12-circuit 430451210 in the same Micro-Fit 3.0 series, the 430452406 doubles the position count at the same 3.00 mm pitch. If your BOM calls for 24 circuits, the 12-position header would require two connectors and two mating harnesses — the 24-position keeps it to one assembly.
