It accepts wire from 12 AWG down to 30 AWG, with each position rated 17.5 A at 300 V. The housing is black polyamide (PA66) and the screw clamp uses a brass rising cage mechanism plated in nickel — the contact surface is brass with tin plating. This is the 4-position member of the Buchanan series, base product number 1546074. ## Wiring and Torque: What the Screw Spec Means in the Field The M3 screw is torqued to 0.79 Nm (7.0 Lb-In) — that is the spec for the rising cage clamp to grip the conductor without damaging the wire or the block. The clamp material is brass with nickel plating, and the screw itself is the same. The 35° (145°) mating orientation means the wire entry is angled relative to the PCB, which helps route wires in tight enclosures where a straight vertical entry would interfere with the cover or adjacent components. ## Ganging Multiple Blocks with the Interlocking Side Feature The side interlocking feature allows multiple 1546074-4 blocks to be mechanically joined side-by-side into a multi-position assembly on the same pitch. This is useful when you need more than 4 positions but want to keep the same 5.08 mm spacing — the blocks snap together without requiring a separate rail or bracket. The single-level design means each block handles one row of 4 circuits.","metaTitle":"TE Connectivity 1546074-4 Buchanan Terminal Block, 4 Pos","metaDescription":"TE Connectivity Buchanan 1546074-4 terminal block, 4 positions, 5.08 mm pitch, 17.5 A, 300 V, screw rising cage clamp, active production, sourced to order.","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":"35° (145°) Angle with Board","Base Product Number":"1546074","Positions Per Level":"4","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":"$2.0200","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.02000","currency":"USD"},{"qty":10,"price":"$1.79700","currency":"USD"},{"qty":25,"price":"$1.78800","currency":"USD"},{"qty":50,"price":"$1.76980","currency":"USD"},{"qty":100,"price":"$1.62390","currency":"USD"},{"qty":250,"price":"$1.61476","currency":"USD"},{"qty":500,"price":"$1.46880","currency":"USD"},{"qty":1000,"price":"$1.31370","currency":"USD"},{"qty":5000,"price":"$1.15861","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/836eaeb9eb53d930c4960055294d2847.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1546074-4?","answer":"Submit a request for current pricing and availability — confirmed at quote time."},{"question":"What is the torque specification for 1546074-4?","answer":"The M3 screw torque is specified at 0.79 Nm (7.0 Lb-In) for the rising cage clamp termination."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1546074-4","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/1546074-4 when reusing this data.
