The 0.438\" (11.12 mm) pitch gives enough spacing between terminals to handle the 20 A per-circuit rating without forcing a tight wire bend radius — sized for the main power feed in a control cabinet or junction box, not a signal line. The dual-wall barrier design with flange provides physical isolation between adjacent circuits and a mounting point for the block. Top termination uses screws with a captive plate — the plate stays captured in the screw, so it does not drop out when the wire is removed. Bottom termination is a 0.250\" quick-connect tab, insulated, which lets you pre-wire a harness with female spade terminals and push it onto the block during assembly. Wire range is 12-22 AWG, covering common power and control conductors.","metaTitle":"Molex Beau 387317202 Barrier Block, 2 Circuits, 0.438\" Pitch, 20 A","metaDescription":"Molex Beau 38731 387317202 barrier block, 2 circuits, 0.438\" (11.12 mm) pitch, 20 A, 300 V, dual-wall, black, panel mount, screws with captive plate, 0.250\" quick connect bottom, U","metaKeywords":null},"attributes":{"series":"Beau 38731","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Color":"Black","Pitch":"0.438\\\" (11.12mm)","title":"387317202","Series":"Beau 38731","Package":"Bulk","Features":"Flange","Wire Gauge":"12-22 AWG","description":"CONN BARRIER STRIP 2CIRC 0.438\\","Barrier Type":"2 Wall (Dual)","Mounting Type":"Chassis, Panel","Number of Rows":"1","Voltage Rating":"300V","Top Termination":"Screws with Captive Plate","Bottom Termination":"Quick Connect (0.250\\\"), Insulated","Number of Circuits":"2","Base Product Number":"038731","Terminal Block Type":"Barrier Block","Current Rating (Amps)":"20A","Material - Insulation":"Thermoplastic","Operating Temperature":"-40°C ~ 100°C","Terminal Screw Finish":"Zinc, Clear Chromate","Number of Wire Entries":"2","Terminal Screw Material":"Steel","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.14","priceTiers":[{"qty":1,"price":"$3.14000","currency":"USD"},{"qty":10,"price":"$2.39700","currency":"USD"},{"qty":25,"price":"$2.24480","currency":"USD"},{"qty":50,"price":"$1.99540","currency":"USD"},{"qty":100,"price":"$1.95200","currency":"USD"},{"qty":250,"price":"$1.80016","currency":"USD"},{"qty":500,"price":"$1.62666","currency":"USD"},{"qty":1000,"price":"$1.44230","currency":"USD"},{"qty":5000,"price":"$1.35555","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/69afd016e6fc91d5bcf7d40792738faf.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/387317202/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the 387317202 barrier block?","answer":"The pitch is 0.438\" (11.12 mm), measured center-to-center between adjacent terminals."},{"question":"Will the 387317202 drop into a panel cutout for the 387317204?","answer":"Yes — both share the same 0.438\" (11.12 mm) pitch, same flange footprint, and same mounting style.
