It accepts 12-22 AWG wire through screw top termination with a closed bottom — the wire enters from the top and terminates against the screw clamp; the closed bottom means no through-panel access, so wiring is entirely front-side. The white UL94 V-0 polyamide (PA66) housing mounts to a chassis or panel, and the dual-row layout gives 6 wire entries (two per circuit). This is the 3-circuit member of the Eurostyle 39100 series, a common choice for power distribution and control wiring in industrial enclosures, lighting panels, and HVAC equipment where a compact, serviceable barrier strip is needed. The housing material is rated UL94 V-0.","metaTitle":"Molex Eurostyle 391001903, 3-Circuit Terminal Strip, 20 A, 300 V","metaDescription":"Molex Eurostyle 39100 391001903 enclosed terminal strip, 3 circuits, 0.315\" (8.00mm) pitch, 20 A, 300 V, 12-22 AWG, screw top/closed bottom, chassis/panel mount, white UL94 V-0 PA6","metaKeywords":null},"attributes":{"series":"Eurostyle 39100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Color":"White","Pitch":"0.315\\\" (8.00mm)","title":"391001903","Series":"Eurostyle 39100","Package":"Bulk","Wire Gauge":"12-22 AWG","description":"CONN TERM STRIP 3CIRC 0.315\\","Barrier Type":"Enclosed","Mounting Type":"Chassis, Panel","Number of Rows":"2","Voltage Rating":"300V","Top Termination":"Screws","Bottom Termination":"Closed","Number of Circuits":"3","Base Product Number":"039100","Terminal Block Type":"Eurostyle Terminal Strip","Current Rating (Amps)":"20A","Material - Insulation":"Polyamide (PA66), Nylon 6/6","Operating Temperature":"-40°C ~ 105°C","Terminal Screw Finish":"Zinc","Number of Wire Entries":"6","Terminal Screw Material":"Steel","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.63","priceTiers":[{"qty":1,"price":"$1.63000","currency":"USD"},{"qty":10,"price":"$1.14200","currency":"USD"},{"qty":25,"price":"$1.06480","currency":"USD"},{"qty":50,"price":"$0.96640","currency":"USD"},{"qty":100,"price":"$0.96220","currency":"USD"},{"qty":250,"price":"$0.81252","currency":"USD"},{"qty":500,"price":"$0.76974","currency":"USD"},{"qty":1000,"price":"$0.68421","currency":"USD"},{"qty":5000,"price":"$0.55592","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/25ef929a4171244647da13d92ede8f69.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/391001903/alternatives.json"},"ai":{"faq":[{"question":"What is the wire range for 391001903?","answer":"The 391001903 accepts 12-22 AWG wire, covering solid and stranded copper for power and signal connections."},{"question":"Will 391001903 drop into a panel specified for 391001904?","answer":"Yes, both use the same 0.315\" (8.00mm) pitch, same mounting, same ratings — the only difference is 3 circuits vs 4 circuits.
