It uses a dual-wall barrier for increased creepage between terminals, top screw termination for field wiring, and a closed bottom — meaning all connections are made from one side, typical for junction boxes or chassis-mount terminal strips. Rated 15 A per circuit at 300 V, it accepts 14-22 AWG wire and provides 8 wire entries (two per circuit) for daisy-chain or feed-through runs. The 0.438\" (11.12 mm) pitch sets the terminal spacing — wide enough to maintain creepage for the 300 V rating without needing oversized board clearance. The 15 A per circuit rating is continuous at the terminal block level; derate above ambient if the enclosure runs hot. The dual-wall barrier (two walls between adjacent terminals) adds physical isolation, which matters for the 300 V working voltage in a panel environment. Top screw termination with a closed bottom means the block mounts flush to the panel and all wiring is done from the accessible face. The flange (feature) provides the mounting holes for chassis or panel attachment. The closed bottom also prevents accidental shorting to the panel behind the block. With 8 wire entries for 4 circuits, each circuit can terminate two wires — useful for looping power to a downstream device without a separate jumper. The 14-22 AWG range covers most control and power wiring in industrial panels.","metaTitle":"Molex Beau 38780 387800204 Barrier Block, 4 Circuit, 0.438\" Pitch, 15A","metaDescription":"Molex Beau 38780 387800204 barrier block, 4 circuits, 0.438\" (11.12mm) pitch, 15A, 300V, dual-wall, top screw termination, closed bottom, chassis/panel mount, 14-22 AWG, black UL94","metaKeywords":null},"attributes":{"series":"Beau 38780","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Color":"Black","Pitch":"0.438\\\" (11.12mm)","title":"387800204","Series":"Beau 38780","Package":"Tray","Features":"Flange","Wire Gauge":"14-22 AWG","description":"CONN BARRIER STRIP 4CIRC 0.438\\","Barrier Type":"2 Wall (Dual)","Mounting Type":"Chassis, Panel","Number of Rows":"2","Voltage Rating":"300V","Top Termination":"Screws","Bottom Termination":"Closed","Number of Circuits":"4","Base Product Number":"038780","Terminal Block Type":"Barrier Block","Current Rating (Amps)":"15A","Material - Insulation":"Thermoplastic","Terminal Screw Finish":"Nickel","Number of Wire Entries":"8","Terminal Screw Material":"Brass","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.47","priceTiers":[{"qty":1,"price":"$4.47000","currency":"USD"},{"qty":10,"price":"$3.40700","currency":"USD"},{"qty":25,"price":"$3.19160","currency":"USD"},{"qty":50,"price":"$2.83680","currency":"USD"},{"qty":100,"price":"$2.77520","currency":"USD"},{"qty":250,"price":"$2.55932","currency":"USD"},{"qty":500,"price":"$2.31264","currency":"USD"},{"qty":1000,"price":"$2.05055","currency":"USD"},{"qty":5000,"price":"$1.92721","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9b5532750e9b587fd2eb215efec78f52.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/387800204/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 387800204 and get a price?","answer":"The 387800204 is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time."},{"question":"What is the pitch of 387800204?","answer":"The pitch is 0.438\" (11.12 mm)."},{"question":"Will 387800204 drop into a panel specified for 387800104?","answer":"Yes — both are 4-circuit blocks with the same 0.438\" pitch, same mounting, same barrier type, and same wire range.
