The MS3120E12-3P is a MIL-DTL-26482 Series I wall mount receptacle in shell size 12 with insert arrangement 12-3, carrying 3 × #16 pin contacts. Series I is the original solder-contact generation of 26482, developed as the miniature companion to MIL-DTL-5015: smaller contacts for lighter-gauge wire, with the same bayonet quick-disconnect coupling.
Class E is environmental, grommet seal. Series I classes are not interchangeable with Series II: a Series I MS3120 is a solder-contact part with front-release contacts, while the equivalent Series II positions use rear-release crimp M39029 contacts and different tooling.
Each #16 contact is rated 13 A at 20 °C; the assembly is rated 600 VAC (RMS) and operates from -55 °C to +125 °C with 5,000 MΩ minimum insulation resistance. Airoadcon supplies the same MIL part number, interchangeable with the original QPL manufacturers.
