It carries a 15 A current rating at 300 V and accepts 14-22 AWG wire, making it a straightforward choice for terminating field wiring in industrial cabinets, HVAC units, and similar equipment where a screw-terminated barrier strip is specified. The dual-row layout gives you 16 wire entries across 8 circuits — each circuit has two screw positions, which is handy when you need to land two wires on the same pole or daisy-chain the feed through the block. The top termination uses screws with a captive plate, so the pressure plate stays under the screw head and won't drop out when you loosen it for re-termination in the field. Housing is black PBT rated UL94 V-0, and the terminal screws are steel with a zinc clear chromate finish. The bottom termination is closed — no through-board pins, so it's strictly a panel-mount block for wire-to-wire or wire-to-busbar connections. The 0.375\" (9.53 mm) pitch provides clearance between adjacent terminals when landing 14 AWG wire. The captive plate on the screw termination is the detail that saves time on site. When you're re-terminating a wire that's worked loose from vibration, the plate doesn't fall out and roll under the panel — you just back the screw off, insert the stripped wire, and torque it down. It accepts 14-22 AWG, so it covers the common control and power wire sizes in a typical panel.","metaTitle":"Molex Beau 38770 387700308 Barrier Block, 8 Circuits, 0.375\" Pitch, 15A 300V","metaDescription":"Molex Beau 38770 387700308 barrier block, 8 circuits, 0.375\" (9.53mm) pitch, 15A at 300V, 14-22 AWG, chassis/panel mount, captive screw termination, black UL94 V-0 PBT housing, RoH","metaKeywords":null},"attributes":{"series":"Beau 38770","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Color":"Black","Pitch":"0.375\\\" (9.53mm)","title":"387700308","Series":"Beau 38770","Package":"Bulk","Features":"Flange","Wire Gauge":"14-22 AWG","description":"CONN BARRIER STRIP 8CIRC 0.375\\","Barrier Type":"2 Wall (Dual)","Mounting Type":"Chassis, Panel","Number of Rows":"2","Voltage Rating":"300V","Top Termination":"Screws with Captive Plate","Bottom Termination":"Closed","Number of Circuits":"8","Base Product Number":"038770","Terminal Block Type":"Barrier Block","Current Rating (Amps)":"15A","Material - Insulation":"Polybutylene Terephthalate (PBT)","Terminal Screw Finish":"Zinc, Clear Chromate","Number of Wire Entries":"16","Terminal Screw Material":"Steel","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.83","priceTiers":[{"qty":1,"price":"$5.83000","currency":"USD"},{"qty":10,"price":"$4.44700","currency":"USD"},{"qty":25,"price":"$4.16480","currency":"USD"},{"qty":50,"price":"$3.70220","currency":"USD"},{"qty":100,"price":"$3.62160","currency":"USD"},{"qty":250,"price":"$3.33996","currency":"USD"},{"qty":500,"price":"$3.01804","currency":"USD"},{"qty":1000,"price":"$2.67599","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/99ec0f09c14140f3386a49dd93c22cbc.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/387700308/alternatives.json"},"ai":{"faq":[{"question":"Will the 387700308 drop into a panel cutout for the 387700306?","answer":"No — the 387700308 has 8 circuits while the 387700306 has 6 circuits at the same 0.375\" pitch, so the 8-circuit block is longer and the mounting flange holes are spaced further apart.
