Product Introduction
The Molex EXTreme Guardian 1510530004 is a 4-position plug with male blades, part of the EXTreme Guardian 151053 series. This is a through-hole solder termination part, intended for wire-to-board power applications where a single row of four heavy-duty blades delivers the main feed.
80 A per circuit is the headline — each power blade carries current typical of a busbar or PSU output. The locking ramp keeps the plug seated against cable strain; in a harness assembly, the audible latch click confirms full engagement before the system powers up.
This connector class is used as a wire-to-board power interconnect in harness assemblies — think server PSU feeds, industrial motor drives, battery pack interconnects, or heavy equipment control cabinets. The locking ramp makes it field-mateable in high-vibration settings without risk of back-out.
