Barrier Block for Panel Wiring — 4 Circuits, Screw Termination
The Molex 0387206304 is a 4-circuit barrier block from the Beau 38720 series, a dual-wall (2 Wall) design that isolates adjacent terminals to prevent accidental shorting between wires. It uses a screw clamp on top to secure 14-22 AWG wire, with a PC pin bottom termination for through-hole soldering to a PCB. The 0.375" (9.53mm) pitch gives generous spacing between circuits for the 300V rating, and the 15A per-circuit current is sized for power distribution in control panels and appliance wiring — not signal-level duty.
Wiring and Termination — Screw Clamp, PC Pin
The single-row layout with 4 wire entries matches the 4 circuits — one wire per position. The dual-wall barrier reduces the chance of a stray strand bridging adjacent terminals during wiring.
