It uses a screw-driven rising cage clamp — the screw pushes a clamp plate down onto the conductor, not the wire itself, so the wire isn't nicked or deformed during termination. The 17.5 A per position rating at 300 V covers most signal-level and low-power distribution circuits inside an enclosure. The 12-30 AWG wire range accepts fine signal wires up to 12 AWG for power feeds; the rising cage clamp handles solid, stranded, and ferruled conductors. ## Mating Orientation and Termination This is a top-entry (vertical with board) orientation — wires enter perpendicular to the PCB surface, so the block sits flat on the board and the screw terminals face upward. The termination is a screw-driven rising cage clamp: strip the wire to the recommended length, insert it into the clamp opening, and tighten the M3 screw to 0.79 Nm. The clamp rises to press the conductor against the current bar — no crimp tool, no ferrule required for solid or stranded wire. Through-hole mounting pins anchor the block to the PCB; the pins are tin-plated brass for solderability.","metaTitle":"TE Buchanan 1546073-3 Terminal Block, 3 Pos, 5.08mm, 17.5 A","metaDescription":"TE Connectivity Buchanan 1546073-3 3-position PCB terminal block, 5.08 mm pitch, 17.5 A, 300 V, screw rising cage clamp, ROHS3 compliant, active production.","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":"Black","Pitch":"0.200\\\" (5.08mm)","Series":"Buchanan","Current":"17.5 A","Package":"Bulk","Voltage":"300 V","Features":"Interlocking (Side)","Wire Gauge":"12-30 AWG","Screw Thread":"M3","Mounting Type":"Through Hole","Product Status":"Active","Torque - Screw":"0.79 Nm (7.0 Lb-In)","lifecycle_stage":"unknown","Housing Material":"Polyamide (PA66), Nylon 6/6","Number of Levels":"1","Wire Termination":"Screw - Rising Cage Clamp","Mating Orientation":"Vertical with Board","Base Product Number":"1546073","Positions Per Level":"3","Operating Temperature":"-40°C ~ 105°C","Clamp Material - Plating":"Brass - Nickel Plated","Screw Material - Plating":"Brass - Nickel Plated","Contact Material - Plating":"Brass - Tin Plated"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4300","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.43000","currency":"USD"},{"qty":10,"price":"$1.33300","currency":"USD"},{"qty":25,"price":"$1.28320","currency":"USD"},{"qty":50,"price":"$1.27080","currency":"USD"},{"qty":100,"price":"$1.14690","currency":"USD"},{"qty":250,"price":"$1.10968","currency":"USD"},{"qty":500,"price":"$1.01050","currency":"USD"},{"qty":1000,"price":"$0.90511","currency":"USD"},{"qty":5000,"price":"$0.81832","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is 1546073-3 RoHS compliant?","answer":"Yes, the 1546073-3 is ROHS3 compliant per the factory specification, so it ships into EU and other regulated markets without exemption paperwork."},{"question":"What is the wire gauge range for 1546073-3?","answer":"The 1546073-3 accepts 12-30 AWG wire, covering fine signal conductors up to 12 AWG power feeds, with solid, stranded, or ferruled wire."},{"question":"What is the torque specification for 1546073-3?","answer":"Tighten the M3 screw to 0.79 Nm (7.0 Lb-In) — that torque provides consistent clamp force without damaging the brass insert."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1546073-3","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/1546073-3 when reusing this data.
