It carries a 45 A current rating per circuit at 600 V, making it suited for industrial power distribution, machine control panels, and HVAC equipment where a single block terminates heavy-gauge wiring to a board. The 0.500\" (12.70 mm) pitch provides clearance for 8-18 AWG wire terminated under screws with captive plates — the zinc yellow chromate steel screws resist corrosion in cabinet environments. The black PBT insulator carries a -40°C to 110°C operating range, and the 3-wall (tri) barrier design prevents stray strands from bridging adjacent terminals. The 600 V rating covers 480 VAC three-phase panels with margin. The 0.500\" pitch is wide enough that adjacent terminals won't arc at this voltage, and the 3-wall barrier physically blocks a loose conductor from contacting the next terminal. The 8-18 AWG range means you can land a 8 AWG power feed on one position and 18 AWG control leads on the others in the same block. Top termination uses screws with captive plates — the plate stays captured in the screw thread, so it doesn't drop out during field wiring. Bottom termination is PC pin for through-hole soldering to a PCB. The single-row layout with 3 wire entries matches the circuit count one-to-one. Terminal screw material is steel with zinc yellow chromate finish, which holds torque better than brass in repeated termination cycles.","metaTitle":"Molex Beau 38660 0386608803 Barrier Block, 3 Circuits, 45 A","metaDescription":"Molex 0386608803 Beau 38660 barrier block, 3 circuits, 0.500\" pitch, 45 A, 600 V. 8-18 AWG, screws with captive plate.
