The 7.50 mm pitch leaves room between positions for the M3 screw and the clamp mechanism, which means the block can handle the 17.5 A per position without the adjacent terminals crowding the heat dissipation. The green polyamide (PA66) housing carries a 300 V rating, matching the typical panel-level distribution voltage inside an industrial control cabinet. ## Wiring and Termination — What the Screw Torque Tells You The rising cage clamp pulls the conductor up against a flat pressure plate when the M3 screw is tightened to 0.79 Nm (7.0 Lb-In). That torque spec is the key to a reliable termination — too little and the wire can pull out under vibration, too much and you strip the threads in the nylon housing. The brass screw and clamp are both nickel-plated, so the corrosion resistance is adequate for a dry indoor cabinet but not for a washdown environment.","metaTitle":"TE Connectivity 282844-4 Buchanan Terminal Block, 4 Position","metaDescription":"TE Connectivity 282844-4 Buchanan PCB terminal block, 4 positions, 7.50 mm pitch, 17.5 A, 300 V, screw rising cage clamp, green.","metaKeywords":null},"attributes":{"series":"Buchanan","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Wire-to-Board Connectors","Wire-to-Board Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Green","Pitch":"0.295\\\" (7.50mm)","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":"Horizontal with Board","Base Product Number":"282844","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":"$2.0600","priceTiers":[{"qty":1,"price":"$2.06000","currency":"USD"},{"qty":10,"price":"$1.83400","currency":"USD"},{"qty":25,"price":"$1.82440","currency":"USD"},{"qty":50,"price":"$1.80580","currency":"USD"},{"qty":100,"price":"$1.65680","currency":"USD"},{"qty":250,"price":"$1.64752","currency":"USD"},{"qty":500,"price":"$1.49860","currency":"USD"},{"qty":1000,"price":"$1.34036","currency":"USD"},{"qty":5000,"price":"$1.18212","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/282844-4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/282844-4","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/282844-4 when reusing this data.
