The 0.374\" (9.50mm) pitch gives enough terminal spacing to handle the 20A per circuit rating without crowding adjacent wires, and the dual-wall (2 Wall) barrier physically isolates each terminal from its neighbour — a detail that matters when you are running 12 AWG at full current and don't want a stray strand bridging to the next circuit. The closed bottom termination means the screw terminals are the only wire entry point; the strip terminates the wires on the top side and the circuit runs internally to the next barrier, which is the standard arrangement for a feed-through or junction-point barrier block in an industrial panel. For a control cabinet distribution block running 12 AWG, that covers most motor starter and solenoid circuits without derating. The 300V voltage rating is typical for industrial control panels inside an enclosure — it is not a high-voltage bus rating, but it covers 277V lighting circuits and 240V equipment feeds. The 12-22 AWG wire range accepts the common power wire (12 AWG) down to signal-level 22 AWG, so the same strip can mix a 20A feed and a smaller control wire on adjacent positions. ## Flange Mount and Dual-Wall Barrier The flange feature means the strip has mounting ears with screw holes for panel or chassis mounting — not a DIN-rail foot, but a direct screw-down to a flat surface. The dual-wall barrier adds a second wall between each terminal pair, which increases creepage distance and reduces the chance of a wire strand or tool bridging two circuits during termination. The terminal screws are steel with a nickel finish; the screw material is steel for strength in repeated tightening, and the nickel finish resists corrosion in a cabinet environment.","metaTitle":"TE Connectivity 1546306-7 Buchanan Barrier Strip, 7 Circuit","metaDescription":"TE 1546306-7 Buchanan barrier strip, 7 circuits, 0.374\" pitch, 20A, 300V, 12-22 AWG, dual-wall barrier, flange mount, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Buchanan","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Terminal Blocks","Barrier Terminal Blocks"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Pitch":"0.374\\\" (9.50mm)","Series":"Buchanan","Package":"Bulk","Features":"Flange","Wire Gauge":"12-22 AWG","Barrier Type":"2 Wall (Dual)","Mounting Type":"Chassis, Panel","Number of Rows":"2","Product Status":"Active","Voltage Rating":"300V","Top Termination":"Screws","lifecycle_stage":"unknown","Bottom Termination":"Closed","Number of Circuits":"7","Base Product Number":"1546306","Terminal Block Type":"Barrier Block","Current Rating (Amps)":"20A","Material - Insulation":"Thermoplastic","Operating Temperature":"-40°C ~ 120°C","Terminal Screw Finish":"Nickel","Number of Wire Entries":"14","Terminal Screw Material":"Steel","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9600","priceTiers":[{"qty":1,"price":"$3.96000","currency":"USD"},{"qty":10,"price":"$3.52700","currency":"USD"},{"qty":25,"price":"$3.50920","currency":"USD"},{"qty":50,"price":"$3.47340","currency":"USD"},{"qty":100,"price":"$3.13140","currency":"USD"},{"qty":250,"price":"$3.11336","currency":"USD"},{"qty":500,"price":"$2.87942","currency":"USD"},{"qty":1000,"price":"$2.57348","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1546306-7/alternatives.json"},"ai":{"faq":[{"question":"Does 1546306-7 have a flange and what is the mounting type?","answer":"Yes, the 1546306-7 includes a flange feature and is designed for chassis or panel mounting."},{"question":"Is 1546306-7 RoHS compliant?","answer":"Yes, the 1546306-7 is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1546306-7","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/1546306-7 when reusing this data.
