The 0.437\" (11.10 mm) pitch gives enough terminal spacing for 14-22 AWG wire landed under screw clamps, with a dual-wall barrier between positions to keep stray strands from shorting adjacent terminals. ## Wiring and Terminating — Screw Clamp, Closed Bottom Top termination uses steel screws with a nickel finish — the screw head clamps the conductor against the current bar. The bottom is closed, meaning the screw does not pass through to the other side; this keeps the block compact and prevents accidental contact with live metal behind the panel. With 8 wire entries across 4 circuits, each circuit has two entry points — useful for daisy-chaining or landing a ring terminal alongside a solid wire. The flange accepts a screw or bolt through each end — the block is meant to be fastened down, not snapped onto a rail. The thermoplastic insulation holds up to the UL94 V-0 flame rating, so the block can be installed inside equipment that requires a flammability-rated component.","metaTitle":"TE Connectivity 1546670-4 Buchanan Barrier Strip, 4 Circuit","metaDescription":"TE Connectivity 1546670-4 Buchanan barrier strip, 4 circuits, 0.437\" pitch, 25A, 300V, 14-22 AWG, dual-wall barrier, flange mount, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Buchanan","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Terminal Blocks","Barrier Terminal Blocks"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Pitch":"0.437\\\" (11.10mm)","Series":"Buchanan","Package":"Bulk","Features":"Flange","Wire Gauge":"14-22 AWG","Barrier Type":"2 Wall (Dual)","Mounting Type":"Chassis, Panel","Number of Rows":"2","Product Status":"Active","Voltage Rating":"300V","Top Termination":"Screws","lifecycle_stage":"unknown","Bottom Termination":"Closed","Number of Circuits":"4","Base Product Number":"1546670","Terminal Block Type":"Barrier Block","Current Rating (Amps)":"25A","Material - Insulation":"Thermoplastic","Operating Temperature":"-40°C ~ 120°C","Terminal Screw Finish":"Nickel","Number of Wire Entries":"8","Terminal Screw Material":"Steel","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0100","priceTiers":[{"qty":1,"price":"$2.01000","currency":"USD"},{"qty":10,"price":"$1.83800","currency":"USD"},{"qty":25,"price":"$1.78360","currency":"USD"},{"qty":50,"price":"$1.76540","currency":"USD"},{"qty":100,"price":"$1.63870","currency":"USD"},{"qty":250,"price":"$1.61156","currency":"USD"},{"qty":500,"price":"$1.46668","currency":"USD"},{"qty":1000,"price":"$1.31278","currency":"USD"},{"qty":5000,"price":"$1.17697","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c7134b5710928e7b5a038d363b966b96.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1546670-4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1546670-4","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/1546670-4 when reusing this data.
