That matters when you are landing a 12 AWG conductor and need the full thread engagement. The bottom termination is an insulated 0.250\" quick-connect tab, which lets you pre-terminate a harness with a standard female quick-disconnect and snap it onto the block without tools. Wire range is 12-22 AWG, covering most panel power and control circuits. ## Mounting and compliance The flange on each end takes a screw for chassis or panel mounting — no DIN rail adapter, so plan for a drilled panel. The terminal screw is steel with a zinc clear chromate finish; the screw material and finish are listed for corrosion resistance in moderate environments.","metaTitle":"Molex Beau 38731 387317204 Barrier Block, 4-Circuit, 20A","metaDescription":"Molex Beau 38731 387317204 barrier block, 4-circuit, 0.438\" pitch, 20A at 300V, flange-mount chassis/panel, top screws with captive plate, bottom 0.250\" quick-connect, UL94 V-0, Ro","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":"387317204","Series":"Beau 38731","Package":"Bulk","Features":"Flange","Wire Gauge":"12-22 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 with Captive Plate","Bottom Termination":"Quick Connect (0.250\\\"), Insulated","Number of Circuits":"4","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":"4","Terminal Screw Material":"Steel","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.55","priceTiers":[{"qty":1,"price":"$4.55000","currency":"USD"},{"qty":10,"price":"$3.46500","currency":"USD"},{"qty":25,"price":"$3.24520","currency":"USD"},{"qty":50,"price":"$2.88480","currency":"USD"},{"qty":100,"price":"$2.82210","currency":"USD"},{"qty":250,"price":"$2.60260","currency":"USD"},{"qty":500,"price":"$2.35174","currency":"USD"},{"qty":1000,"price":"$2.08520","currency":"USD"},{"qty":5000,"price":"$1.95978","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/69afd016e6fc91d5bcf7d40792738faf.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/387317204/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation is available for the 387317204?","answer":"The 387317204 is ROHS3 compliant and carries a UL94 V-0 flammability rating on the insulation material.
