MIL-DTL-22992 Class L is the largest heavy-duty circular power series qualified to roughly 40–200 A and 600 V, built for quick-disconnect, waterproof power distribution. The N finish is the nickel alternative to the standard C cadmium, chosen where a cadmium-free surface is required, and shell 44 is the mid-point of the 28/32/44/52 range with a 12-contact arrangement.
