The 0.375\" (9.53 mm) pitch gives adequate spacing for 300 V working voltage and 25 A per circuit, with the dual-wall barrier providing physical isolation between adjacent terminals. Top termination uses screws with a captive plate. Bottom termination is a solder turret, insulated. Wire range is 12-22 AWG. Terminal screws are steel with a zinc clear chromate finish.","metaTitle":"Molex Beau 38720 387203803 Barrier Strip, 3 Circuits, 25 A","metaDescription":"Molex Beau 38720 barrier strip, 3 circuits, 0.375\" (9.53 mm) pitch, 25 A, 300 V, flange mount, dual-wall barrier, screws with captive plate, solder turret, 12-22 AWG, -40°C to 100°","metaKeywords":null},"attributes":{"series":"Beau 38720","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Color":"Black","Pitch":"0.375\\\" (9.53mm)","title":"387203803","Series":"Beau 38720","Package":"Bulk","Features":"Flange","Wire Gauge":"12-22 AWG","description":"CONN BARRIER STRIP 3CIRC 0.375\\","Barrier Type":"2 Wall (Dual)","Mounting Type":"Chassis, Panel","Number of Rows":"1","Voltage Rating":"300V","Top Termination":"Screws with Captive Plate","Bottom Termination":"Solder Turret, Insulated","Number of Circuits":"3","Base Product Number":"038720","Terminal Block Type":"Barrier Block","Current Rating (Amps)":"25A","Material - Insulation":"Thermoplastic","Operating Temperature":"-40°C ~ 100°C","Terminal Screw Finish":"Zinc, Clear Chromate","Number of Wire Entries":"3","Terminal Screw Material":"Steel"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.51","priceTiers":[{"qty":1,"price":"$4.51000","currency":"USD"},{"qty":10,"price":"$3.43600","currency":"USD"},{"qty":25,"price":"$3.21840","currency":"USD"},{"qty":50,"price":"$2.86080","currency":"USD"},{"qty":100,"price":"$2.79860","currency":"USD"},{"qty":250,"price":"$2.58096","currency":"USD"},{"qty":500,"price":"$2.33220","currency":"USD"},{"qty":1000,"price":"$2.06788","currency":"USD"},{"qty":5000,"price":"$1.94349","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/ddbce7eea888c8366ffee0630bcdfdee.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/387203803/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch on the 387203803?","answer":"The pitch is 0.375\" (9.53 mm) between centers."},{"question":"Will the 387203803 drop into a panel cutout for the 387203204?","answer":"Yes — both share the same flange mount, dual-wall barrier, and 0.375\" pitch, so the panel cutout and mounting pattern are identical.
