The Molex 430450200 is a 2-position, dual-row right-angle header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power and signal interconnects. It carries an 8 A per circuit current rating and a 600 V voltage rating, with a 3.00 mm row spacing that provides enough creepage for the 600 V rating without an oversized footprint. Typical applications include automotive, industrial, medical, and telecom equipment where a vibration-resistant, field-serviceable connection is needed.
The 600 V rating tells you the creepage distance across the 3.00 mm row spacing is adequate for bus-level voltages in industrial or automotive harnesses.
