The Molex Beau 38690 386907602 is a 2-circuit barrier block on a 0.325" (8.26 mm) pitch, built for panel or board-mount power distribution where a screw-terminated, captive-plate connection is preferred over a crimp or IDC interface. The three-wall barrier design isolates each circuit from adjacent terminals, reducing the chance of a stray strand bridging across terminations during wiring.
Top termination uses screws with a captive plate — the plate stays under the screw head, so the wire wraps around the screw shank rather than pulling out from under a loose washer. Accepts 12-22 AWG, which covers the common range for a 20 A power circuit.
Comparison with Beau 38720 Siblings
The 386907602 uses a 0.325" (8.26 mm) pitch and is rated 20 A, while the Beau 38720 2-circuit variants (387206202, 387207502, 387207402) step up to a 0.375" (9.53 mm) pitch. The 38720 line also uses a 2-wall (dual) barrier instead of the 3-wall (tri) barrier on the 38690. The wider pitch and dual barrier mean the 38720 blocks occupy slightly more board width per circuit but offer a different current rating — 15 A for 387206202, 25 A for the other two. If board space is tight and the 20 A rating fits, the 38690 is the denser choice; if the panel already has 0.375"-pitch cutouts or you need 25 A per circuit, the 387207502 or 387207402 are the correct drop-in for that footprint.
