It is a dual-row, black thermoplastic housing with a 0.438\" (11.12 mm) pitch, designed for chassis or panel mounting via its integral flange. This block terminates 14-22 AWG wire with top-entry screws and a closed bottom, making it a straightforward choice for power distribution and control wiring where a fixed, serviceable connection point is needed. Rated 15 A at 300 V, the 387800105 handles typical panel-level loads without derating for most industrial environments. The 2-wall (dual) barrier design provides physical isolation between adjacent terminals, reducing the risk of accidental shorting from a stray wire strand or tool. Terminal screws are steel with a zinc, clear chromate finish, offering corrosion resistance in a standard cabinet environment. ## Position count and panel fit The 387800105 carries 5 circuits with 10 wire entries (two per circuit). Against the 4-circuit 387800104 at the same 0.438\" (11.12 mm) pitch, the 5-circuit version adds one more terminal position within the same block width increment. If a panel was laid out for the 387800104, the 387800105 will not drop in without adjusting the mounting hole spacing — the flange positions shift with the circuit count. Match the circuit count to the BOM line; the pitch and terminal style are identical across the series.","metaTitle":"Molex Beau 38780 387800105, 5 Circuit Barrier Strip, 0.438\" Pitch","metaDescription":"Molex Beau 38780 387800105 barrier terminal block, 5 circuits, 0.438\" (11.12 mm) pitch, 15 A, 300 V, 14-22 AWG, top screw termination, flange mount, UL94 V-0.
