The dual-wall barrier between terminals gives you extra creepage and keeps a stray strand from shorting to the next circuit when you're cinching down the screw. Top side is a screw clamp — strip the wire, land it under the pressure plate, torque the brass screw with nickel finish. No crimp tool, no ferrule required, though a ferrule keeps stranded wire from splaying. Bottom side is a solder turret: you solder a wire or a PCB trace to the turret for a permanent connection underneath the panel. The flange on each end takes a #6 or M3.5 screw for panel mounting — the block sits flat against the chassis and the solder turrets poke through a cutout. The 0.438\" (11.12 mm) pitch is wide — you get generous spacing between terminals, which matters when you're landing 14 AWG stranded wire with a heavy-duty screwdriver. The 15 A rating at 300 V is the per-circuit maximum; in a 4-circuit block the total heat adds up, so derate if all four circuits are pulling near 15 A inside a sealed enclosure. The -40°C to 100°C operating range covers unheated industrial cabinets and outdoor telecom shelters.","metaTitle":"Molex Beau 38740 0387409704 Barrier Block, 4 Circuit, 15A","metaDescription":"Molex 0387409704 Beau 38740 barrier block, 4 circuits, 15A, 300V, 14-22 AWG, screw/solder turret, UL94 V-0.
