MS3456L28-21P is a MIL-DTL-5015 (SAE-AS50151) Series III straight plug in the largest common shell size, 28, with the 28-21 insert arrangement — thirty-seven size 16 contacts at 13 A each. This is the classic mid-density power-and-control layout for ground-support, marine and heavy-industrial harnesses, where a single threaded-coupling connector carries the whole bundle.
Series III is the crimp rear-release generation of the 5015 interface: contacts are inserted and extracted from the rear with standard tooling, so a damaged contact does not condemn the connector. The threaded coupling ring gives a vibration-resistant joint without a bayonet detent, which is why 5015 remains the default for stationary and heavy-machinery installations. The matching receptacles are MS3450 or MS3452 in shell 28 arrangement 28-21 with socket contacts.
