The green PA66 housing is rated for 300 V and carries a 17.5 A current rating per position, which means each terminal can handle a solid load circuit without derating at room ambient. The rising cage clamp termination accepts 12-30 AWG wire, and the M3 screw is torqued to 0.79 Nm (7.0 Lb-In) — that torque value is the spec to hit for reliable clamp force without stripping the brass-nickel screw. ## Wiring the Clamp — What 12-30 AWG and 0.79 Nm Mean in Practice The rising cage clamp captures the conductor between the clamp body and the screw tip. For 12 AWG solid wire, the full 17.5 A rating is available; at 30 AWG, the current should be derated because the smaller conductor cannot carry the full rating without exceeding its own temperature limit. The M3 screw with brass-nickel plating requires 0.79 Nm of torque — under-torquing leaves the wire loose, over-torquing can strip the threads in the PA66 housing. The side interlocking feature lets you snap multiple 282851-4 blocks together into a multi-position assembly without a separate mounting rail, which is useful when the board needs more than 4 positions at the same pitch.","metaTitle":"TE Connectivity 282851-4 Buchanan Terminal Block, 4 Position","metaDescription":"TE Connectivity 282851-4 Buchanan PCB terminal block, 4 positions, 5.08 mm pitch, 17.5 A, 300 V, green PA66 housing, screw rising cage clamp, M3 screw, 0.79 Nm","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":"0.200\\\" (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":"282851","Positions Per Level":"4","Operating Temperature":"-","Clamp Material - Plating":"Brass - Nickel Plated","Screw Material - Plating":"Brass - Nickel Plated","Contact Material - Plating":"Brass - Tin Plated"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8000","priceTiers":[{"qty":1,"price":"$1.80000","currency":"USD"},{"qty":10,"price":"$1.64400","currency":"USD"},{"qty":25,"price":"$1.59520","currency":"USD"},{"qty":50,"price":"$1.57920","currency":"USD"},{"qty":100,"price":"$1.46570","currency":"USD"},{"qty":250,"price":"$1.44144","currency":"USD"},{"qty":500,"price":"$1.31188","currency":"USD"},{"qty":1000,"price":"$1.17421","currency":"USD"},{"qty":5000,"price":"$1.05274","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/81589c4d2aab8279e8086e0451be0624.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/282851-4/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the TE Connectivity 282851-4 terminal block?","answer":"Submit a request for quote to confirm current availability and pricing for your required quantity."},{"question":"What is the wire range and torque specification for the 282851-4?","answer":"The 282851-4 accepts 12-30 AWG wire and the M3 screw torque specification is 0.79 Nm (7.0 Lb-In).
