What it is
The 1736934636 is a power-class socket contact from Molex's EXTreme Ten60Power 172512 series — a stamped-and-formed crimp terminal that houses inside the matching Ten60Power receptacle body. It accepts 14-16 AWG wire and terminates by crimp, so it needs the appropriate Molex applicator die set for production termination.
55 A at the contact, gold at 30 µin
The 55 A per-contact rating is the single-circuit ceiling at the terminal, not a bus rating across multiple contacts. This contact is sized for 14-16 AWG wire; the barrel matches that conductor range and the current density through the crimp is specified at 55 A. The gold plating at 30.0 µin (0.76 µm) provides contact resistance stability across repeated mating cycles compared to tin.
