The 0.438\" (11.12 mm) pitch gives enough spacing between terminals for 14-22 AWG wire termination without crowding adjacent connections. This is the flanged chassis-mount version — the mounting ears take the mechanical load off the solder turrets when the block is bolted to a panel. The 15 A per-circuit rating is continuous at the rated temperature — the limiting factor is the thermoplastic insulation (UL94 V-0) and the screw-clamp contact interface, not the solder turret bottom termination. The 300 V rating is the working voltage between adjacent circuits, which the 0.438\" pitch supports without tracking across the barrier wall.","metaTitle":"Molex Beau 38739 387390106, 4-Circuit Barrier Strip, 0.438\" Pitch, 15 A","metaDescription":"Molex Beau 38739 387390106 barrier strip, 4 circuits, 0.438\" (11.12 mm) pitch, 15 A, 300 V, 14-22 AWG, screw top, solder turret bottom, flanged chassis mount, black UL94 V-0 housin","metaKeywords":null},"attributes":{"series":"Beau 38739","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Color":"Black","Pitch":"0.438\\\" (11.12mm)","title":"387390106","Series":"Beau 38739","Package":"Bulk","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":"1","Voltage Rating":"300V","Top Termination":"Screws","Bottom Termination":"Solder Turret","Number of Circuits":"4","Base Product Number":"038739","Terminal Block Type":"Barrier Block","Current Rating (Amps)":"15A","Material - Insulation":"Thermoplastic","Operating Temperature":"-40°C ~ 100°C","Number of Wire Entries":"4","Terminal Screw Material":"Steel, Stainless","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.84","priceTiers":[{"qty":1,"price":"$5.84000","currency":"USD"},{"qty":10,"price":"$4.44900","currency":"USD"},{"qty":25,"price":"$4.16760","currency":"USD"},{"qty":50,"price":"$3.70460","currency":"USD"},{"qty":100,"price":"$3.62400","currency":"USD"},{"qty":250,"price":"$3.34212","currency":"USD"},{"qty":500,"price":"$3.02000","currency":"USD"},{"qty":1000,"price":"$2.67773","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/387390106/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the Molex 387390106 barrier strip?","answer":"The 387390106 has a 0.438\" (11.12 mm) pitch between circuits."},{"question":"Will the 387390106 drop into a panel specified for the 387409704?","answer":"Yes, the 387390106 and 387409704 share the same 4-circuit count, 0.438\" pitch, flanged chassis mount, and screw/solder turret termination — they are mechanically interchangeable for the same panel cutout and wiring layout.
