The 0.375\" (9.53 mm) pitch gives generous spacing between terminals for 14-22 AWG wire, reducing the risk of accidental bridging during termination. ## Rated for Continuous Duty Steel terminal screws with a zinc, clear chromate finish resist corrosion in normal panel conditions. ## 12 Circuits vs 9, 10, and 16 in the Same Series The 387206312 is the 12-circuit member of the Beau 38720 family, sharing the same 0.375\" (9.53 mm) pitch, 15 A / 300 V rating, dual-wall barrier, and top-screw / bottom PC-pin termination with its siblings. The 387206309 (9 circuits), 387206310 (10 circuits), and 387206316 (16 circuits) are electrically and mechanically identical per circuit — the only difference is the position count.","metaTitle":"Molex Beau 38720 387206312, 12-Circuit Barrier Block, 0.375\" Pitch","metaDescription":"Molex Beau 38720 barrier block, 387206312, 12 circuits, 0.375\" (9.53 mm) pitch, 15 A, 300 V, top-screw / bottom PC-pin termination, 14-22 AWG, UL94 V-0.
