Your PP45 setup is pulling 45A and the contact you grabbed was rated for less. That's how you get hot terminals and melted insulation at the crimp point. This individual contact is spec'd for AWG10-14 wire at 45A in the PP45 series. Crimp it to your gauge, seat it in the housing, and the connection holds under load
