The black PA66 housing carries the Buchanan series interlocking feature on the side, so multiple 796949-3 blocks can be snapped together to build a wider multi-circuit strip without a separate jumper bar. ## Wire Range and Termination Reality The 796949-3 accepts wire from 12 AWG to 30 AWG — that is a wide span, but the 12 AWG end is where the 17.5 A rating becomes usable. At 12 AWG the rising cage clamp has enough contact area to carry the full current without excessive temperature rise; at 30 AWG the clamp still grips, but the current should be derated because the wire itself limits the ampacity. The M3 screw has a specified torque of 0.79 Nm (7.0 Lb-In) — that is the setting to apply with a torque driver. Under-torquing leaves the clamp loose and the connection resistive; over-torquing can strip the PA66 threads or deform the brass clamp plate. The screw and clamp are both brass with nickel plating, which resists corrosion in industrial atmospheres better than plain steel. Rated 17.5 A per position at 300 V. The 17.5 A figure is per-circuit, not total — a 3-position block can carry 17.5 A on each of the three circuits simultaneously as long as the total temperature rise stays within the PA66 limit.","metaTitle":"TE Buchanan 796949-3 PCB Terminal Block, 3 Pos, 5.08mm","metaDescription":"TE Connectivity Buchanan 796949-3 terminal block, 3 positions, 0.200\" (5.08 mm) pitch, 17.5 A, 300 V, screw rising cage clamp, side entry.","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":"Horizontal with Board","Base Product Number":"796949","Positions Per Level":"3","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":"$1.5800","priceTiers":[{"qty":1,"price":"$1.58000","currency":"USD"},{"qty":10,"price":"$1.44300","currency":"USD"},{"qty":200,"price":"$1.28685","currency":"USD"},{"qty":1000,"price":"$1.03089","currency":"USD"},{"qty":5000,"price":"$0.92425","currency":"USD"},{"qty":10000,"price":"$0.87990","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7593131d75b0e5af26c7bf70112f9d10.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/796949-3/alternatives.json"},"ai":{"faq":[{"question":"Is the 796949-3 RoHS compliant?","answer":"Yes, the 796949-3 carries ROHS3 compliance status, meaning it meets the latest EU RoHS directive including the exemption for lead in certain applications."},{"question":"Can I use 796949-3 with 12 AWG wire?","answer":"Yes, the wire range is 12-30 AWG, so 12 AWG solid or stranded wire is accepted by the rising cage clamp.
