It accepts 16-28 AWG wire and is rated 12 A at 300 V, with a single-level, horizontal-with-board wire entry orientation. The green polyamide (PA66) housing is standard for ground/earth identification in panel wiring conventions, and the -40°C to 110°C operating range suits it for industrial control cabinets, HVAC equipment, and outdoor telecom enclosures where a reliable, field-serviceable screw termination is preferred over a crimp connector. ## Key Ratings and Termination Detail The rising cage clamp termination uses a nickel-plated copper alloy screw and clamp. The 16-28 AWG range covers most signal and low-power control wiring.","metaTitle":"TE Buchanan 1546551-3 Terminal Block, 3 Pos, 3.50mm, 12 A","metaDescription":"TE Connectivity Buchanan 1546551-3 PCB terminal block, 3 positions, 0.138\" (3.50mm) pitch, 12 A, 300 V, screw rising cage clamp, green housing.","metaKeywords":null},"attributes":{"series":"Buchanan","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Wire-to-Board Connectors","Wire-to-Board Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Green","Pitch":"0.138\\\" (3.50mm)","Series":"Buchanan","Current":"12 A","Package":"Bulk","Voltage":"300 V","Features":"-","Wire Gauge":"16-28 AWG","Screw Thread":"-","Mounting Type":"Through Hole","Product Status":"Active","Torque - Screw":"-","lifecycle_stage":"unknown","Housing Material":"Polyamide (PA66), Nylon 6/6","Number of Levels":"1","Wire Termination":"Screw - Rising Cage Clamp","Mating Orientation":"Horizontal with Board","Base Product Number":"1546551","Positions Per Level":"3","Operating Temperature":"-40°C ~ 110°C","Clamp Material - Plating":"Copper Alloy - Nickel Plated","Screw Material - Plating":"Copper Alloy - Nickel Plated","Contact Material - Plating":"Copper Alloy - Tin Plated"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2200","priceTiers":[{"qty":1,"price":"$1.22000","currency":"USD"},{"qty":10,"price":"$1.13900","currency":"USD"},{"qty":25,"price":"$1.09680","currency":"USD"},{"qty":50,"price":"$1.08620","currency":"USD"},{"qty":100,"price":"$0.98030","currency":"USD"},{"qty":250,"price":"$0.94848","currency":"USD"},{"qty":500,"price":"$0.86368","currency":"USD"},{"qty":1000,"price":"$0.77360","currency":"USD"},{"qty":5000,"price":"$0.69942","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8d6720abdfc7a022aa8c17a6561dc055.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1546551-3/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1546551-3","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/1546551-3 when reusing this data.
