What this housing is
The Molex 436802003 is the 3-circuit member of the Sabre 43680 series — a free-hanging plug housing that accepts separately ordered male blade crimp terminals. Pitch is 7.50 mm (0.295 inch) and the housing carries a locking ramp that mechanically secures the mating half once seated.
Current rating and what it means for the circuit
Rated 18 A per circuit — that is the per-contact limit at the housing's operating ceiling of 75°C. The 3-position count at this current rating makes the Sabre series a common fit for low-to-medium power wire-to-wire runs in industrial equipment, not signal-density board interconnects.
What it mates with
The 436802003 mates with the matching Sabre 43680 receptacle housing in the same 3-position count. Stacking direction is side-to-side, meaning this housing orients with its mating half in the same plane — typical for in-line wire-to-wire harness splices rather than board-to-board stacks.
