It uses a screw-actuated rising cage clamp to secure 16-28 AWG wire against a tin-plated copper alloy contact, with the wire entry oriented horizontally with the board — a layout that keeps the wiring parallel to the PCB plane for tighter enclosure fit. The 0.150\" (3.81mm) pitch spaces the three positions enough to handle the 150 V / 12 A rating without forcing a wide board footprint, and the polyamide (nylon) housing carries a -40°C to 110°C operating range, suited for industrial control cabinets and HVAC equipment where the terminal block lives inside an enclosure with no direct moisture exposure. The 12 A per-position rating is the block's maximum continuous current at the rated voltage of 150 V. For a 3-circuit block, that means 12 A per circuit individually, not summed — each terminal carries its own load. The 150 V is the max working voltage between adjacent positions or to ground; for most low-voltage control circuits (24 VDC, 120 VAC) this is generous headroom. The wire gauge range of 16-28 AWG covers common field wiring: 16 AWG for power feeds up to the full 12 A, 18-20 AWG for typical control signals, and 22-28 AWG for smaller sensor loops. The tin-plated contact is adequate for the rated current and the moderate mating cycle count of a screw-clamp terminal — the clamp force, not the plating, carries the current. ## Screw Rising Cage Clamp Termination The rising cage clamp works by turning the screw to lift a nickel-plated copper alloy clamp plate inside the housing, trapping the stripped wire between the plate and the current bar. It does not require a ferrule, though one can help with fine-stranded wire. The screw and clamp are both nickel-plated copper alloy, which resists corrosion in the typical industrial cabinet environment. The through-hole solder pins anchor the block to the PCB — the screw torque is applied after soldering, so the board must be supported to avoid lifting the pads.","metaTitle":"TE Connectivity Buchanan 1776113-3","metaDescription":"TE Connectivity Buchanan 1776113-3 terminal block, 3 positions, 0.150\" (3.81mm) pitch, 12 A, 150 V, screw rising cage clamp, through hole, black.","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":"0.150\\\" (3.81mm)","Series":"Buchanan","Current":"12 A","Package":"Bulk","Voltage":"150 V","Features":"-","Wire Gauge":"16-28 AWG","Screw Thread":"-","Mounting Type":"Through Hole","Product Status":"Active","Torque - Screw":"-","lifecycle_stage":"unknown","Housing Material":"Polyamide (PA), Nylon","Number of Levels":"1","Wire Termination":"Screw - Rising Cage Clamp","Mating Orientation":"Horizontal with Board","Base Product Number":"1776113","Positions Per Level":"3","Operating Temperature":"-40°C ~ 110°C","Clamp Material - Plating":"Copper Alloy - Nickel Plated","Screw Material - Plating":"Copper Alloy - Nickel Plated","Contact Material - Plating":"Copper Alloy - Tin Plated"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1900","priceTiers":[{"qty":1,"price":"$2.19000","currency":"USD"},{"qty":10,"price":"$1.94800","currency":"USD"},{"qty":25,"price":"$1.93800","currency":"USD"},{"qty":50,"price":"$1.91800","currency":"USD"},{"qty":100,"price":"$1.75990","currency":"USD"},{"qty":250,"price":"$1.75000","currency":"USD"},{"qty":500,"price":"$1.59180","currency":"USD"},{"qty":1000,"price":"$1.42373","currency":"USD"},{"qty":5000,"price":"$1.25565","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1776113-3/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of 1776113-3?","answer":"The 1776113-3 is rated 12 A per position at 150 V.
