What it is
The Molex 1720420301 is a 3-position single-row male-blade header in the Super Sabre 172042 family, operating at 7.50 mm pitch and rated 30 A per circuit at 600 V. Silver-plated copper contacts sit in a black glass-filled LCP housing that spans -40°C to 125°C, and the finger-proof shroud with a locking ramp keeps the mated pair seated under vibration or mechanical stress.
What the ratings mean
At 30 A per circuit the Super Sabre targets power-interconnect duty — motor drives, inverters, and industrial equipment panels where the panel builder needs a single connector to carry a full load branch without a pigtail splice. The 600 V rating is supported by the 7.50 mm pitch; that clearance between adjacent blade positions is what makes the voltage class viable without external creepage additions.
Finger-proof and locking ramp
The finger-proof shroud encloses the live blade face so a technician cannot contact the energized metal during installation or field servicing — a meaningful safety feature on a 600 V unit. The locking ramp on the housing body engages the matching receptacle positively; the audible click tells the installer the pair is seated before the panel door closes.
Where this class is used
Super Sabre headers are board-to-wire power connectors used in industrial automation cabinets, motor-drive lineups, and equipment that requires a field-wirable power feed at panel entry. The through-hole solder legs give a permanent mechanical anchor on the PCB — this is not a floating connector but a fixed panel-mount header designed to mate with a matching plug housing on a wire harness.
