The 4-1123724-2: It mates with the matching Economy Power receptacle housing via a friction lock — no secondary latch needed, just push until it clicks. The single-wall shroud guides the plug during mating and protects the pins from accidental shorting. Applications include general-purpose industrial, lighting, and similar wire-to-board power distribution where the current per circuit stays under 7.5 A and the board stack-up allows a through-hole solder tail.
The 7.5 A rating is per contact at the listed temperature range (-25°C to 105°C). Derate current if the ambient inside the enclosure exceeds 85°C — the PBT housing (UL94 V-0) limits the continuous thermal rise. Only 2 of the 3 positions are loaded with pins.
