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.","metaTitle":"Molex Beau 38720 0387206304 Barrier Block, 4 Circuits, 15A","metaDescription":"Molex 0387206304 Beau 38720 series barrier block, 4 circuits, 0.375\" pitch, 15A, 300V, UL94 V-0.
