The 464369304: 60 A per circuit is the headline — each blade carries the main DC rail current, not a signal line. The press-fit termination avoids solder defects and makes rework straightforward on a backplane or power distribution board. The 600VAC / 250VDC dual rating means the DC ceiling is lower than the AC figure; for a 250 VDC bus this connector is at its rated limit, so derate if the bus runs above that.
Position count comparison within the series
The 4-position 464369304 shares the same 0.217" pitch, 60 A rating, press-fit termination, and 30.0µin gold plating as the 6-position 464369306. If the BOM calls for 6 circuits, the 464369306 is the direct match; the 4-position variant fits only when the circuit count is exactly 4.
