HubbellCS6365C Locking Plug, 50 amp, 125/250V, 3 Pole and 4 Wire

Does this have three prongs?

I have an mq 45 kw generator, i need the plugs to connect to the 50 amp twist lock, is this the right one?

Will this cs6365c mate correctly with a cs6369 female connector on my 10kw diesel generator?

Can you show how to place wires to it
