It is a panel-mount screw-clamp block with closed-bottom construction, meaning the screw terminals are accessed from the top and the wire entries are enclosed on the bottom side. This is the kind of block you spec for a control cabinet junction point or a power distribution terminal rail where you need a field-serviceable, vibration-resistant connection that doesn't require a PCB. The dual-wall barrier between each circuit provides physical isolation that prevents accidental shorting between adjacent terminals when you're landing 12 AWG power feeds. Rated 20A per circuit at 300V, this block handles the typical 24 VDC control power bus or a 120 VAC lighting circuit without derating concern at room temperature. The 0.374\" (9.50mm) pitch is wide enough that you can land 12 AWG stranded wire with a standard screwdriver without crowding the adjacent terminal — the 2 Wall (Dual) barrier keeps the conductor contained. The 12-22 AWG wire range means you can mix a 12 AWG power feed on one circuit and 18 AWG sensor wiring on the next. Mounts to a chassis or panel via the integral flange — the flange provides a positive mechanical anchor that keeps the block from shifting when you torque the screw terminals. The top termination uses steel screws with a nickel finish; the closed bottom means the screw threads are captive and the wire is clamped against a current-carrying bar. With 6 wire entries across 3 circuits (2 wires per circuit), you can daisy-chain power through the block by landing an incoming and outgoing wire under the same screw. The black housing is the standard industrial color for this series.","metaTitle":"TE Buchanan 1546306-3 Barrier Strip, 3 Circuit, 0.374\" Pitch","metaDescription":"TE Connectivity Buchanan 1546306-3 barrier block, 3 circuits, 0.374\" pitch, 20A, 300V, 12-22 AWG, screw termination, UL94 V-0, RoHS3.","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":"3","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":"6","Terminal Screw Material":"Steel","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3800","priceTiers":[{"qty":1,"price":"$1.38000","currency":"USD"},{"qty":10,"price":"$1.29100","currency":"USD"},{"qty":25,"price":"$1.24320","currency":"USD"},{"qty":50,"price":"$1.23100","currency":"USD"},{"qty":100,"price":"$1.11100","currency":"USD"},{"qty":250,"price":"$1.07496","currency":"USD"},{"qty":500,"price":"$0.97886","currency":"USD"},{"qty":1000,"price":"$0.87677","currency":"USD"},{"qty":5000,"price":"$0.79269","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1546306-3/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 1546306-3?","answer":"The pitch is 0.374\" (9.50mm) center-to-center between circuits."},{"question":"What is the wire range for 1546306-3?","answer":"It accepts 12-22 AWG wire under the screw terminals."},{"question":"Is 1546306-3 RoHS compliant?","answer":"Yes, it is ROHS3 Compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1546306-3","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/1546306-3 when reusing this data.
