The 641831-1: At 12 A per circuit, the temperature rise stays within the UL94 V-0 PA/nylon housing limit when all six circuits are loaded simultaneously at 25 °C ambient. The 600 VAC rating covers most industrial and appliance power distribution inside an enclosure.
The mating half is a Universal MATE-N-LOK receptacle housing that accepts the corresponding crimp terminals. The locking ramp on the header engages with the receptacle latch — confirm the circuit count and keying match your receptacle part number.
