It accepts Mini-Fit Jr 5558-series crimp terminals, making it a field-terminable building block for heavy-current harnesses in industrial cabinets, power distribution units, and battery interconnect assemblies. The 43A per-circuit rating at 250V places this insert well into power-grade territory — each circuit carries bus-level current, not signal-level. Rated 43A per circuit at 250V, the 12-position HMC insert handles the main DC rail or AC branch circuit without derating at room temperature. Natural colour housing, bulk packaging. The 12-position layout is keyed to prevent mis-mating. No contacts are included — the insert body alone, ready for terminal loading.","metaTitle":"Molex HMC 512031200 Male Insert, 12 Pos, 43A, 250V","metaDescription":"Molex HMC series male insert without contacts, 12 positions, 43A per circuit at 250V, Mini-Fit Jr 5558 interface, UL94 V-0, -55 to 125°C.
