The Molex 0439382102 is an 8-circuit, 2-row plug from the Mini-Fit Sr 43938 series — the high-current branch of the Mini-Fit family, built for power distribution in wire-to-wire and wire-to-board harnesses. The 0.394" (10.00mm) pitch is the widest in the Mini-Fit line, giving each circuit the creepage and conductor space to handle bus-level current without the housing overheating.
You need to order the male crimp terminals separately. The Mini-Fit Sr male pin terminal, Molex order code 0439380001, is the standard mate. It accepts 8 AWG to 14 AWG wire and is rated for the full current the housing can carry.
Rated for the Power Bus, Not a Signal Line
The 10.00 mm pitch provides creepage and conductor space for power distribution. The latch holder keeps the plug locked to the receptacle under vibration.
