This enclosed barrier strip uses a 0.472\" (12.00mm) pitch between terminals, giving each screw position enough physical spacing to handle the 40A current rating without creepage issues. Wire connections are made via top-entry screws with a zinc/non-hexavalent chromate finish on steel; the bottom termination is closed, meaning the strip mounts directly to a chassis or panel and the wiring exits through the open side. Accepts 10-22 AWG wire, so it covers both heavy power feeds (10 AWG) and lighter control wiring (22 AWG) on the same block. ## 40A at 250V — Power Distribution on a 12 mm Pitch The 40A per-circuit rating puts this strip in the power distribution class — each screw terminal can carry bus-level current for a sub-panel, a heater load, or a motor branch circuit. The 250V voltage rating covers single-phase AC or DC control circuits up to that potential. The 12.00 mm pitch means the terminal spacing is wide enough to land 10 AWG stranded wire with a ring or fork terminal without crowding adjacent screws. The enclosed barrier design separates each circuit with a physical wall, reducing the chance of a stray conductor bridging two terminals during wiring or service. ## Mounting and Wiring The strip mounts to a chassis or panel using the mounting holes at each end — no DIN rail adapter, so plan for screw-down installation. The top termination uses screws; the closed bottom means the strip is not intended for pass-through wiring. Eight wire entries (two per circuit) allow daisy-chaining or dual-feed on the same terminal. The natural colour and polyamide insulation are standard for indoor industrial control panels; the UL94 V-2 rating is acceptable for most equipment enclosures, though some applications may specify V-0.","metaTitle":"TE 1776302-4 TSB1000 Barrier Strip, 4 Circuit, 40A","metaDescription":"TE Connectivity 1776302-4 Eurostyle terminal strip, 4 circuits, 0.472\" pitch, 40A, 250V, 10-22 AWG, screws top, closed bottom, UL94 V-2, RoHS3.","metaKeywords":null},"attributes":{"series":"TSB1000, Buchanan","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Terminal Blocks","Barrier Terminal Blocks"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Natural","Pitch":"0.472\\\" (12.00mm)","Series":"TSB1000, Buchanan","Package":"Bulk","Features":"-","Wire Gauge":"10-22 AWG","Barrier Type":"Enclosed","Mounting Type":"Chassis, Panel","Number of Rows":"2","Product Status":"Active","Voltage Rating":"250V","Top Termination":"Screws","lifecycle_stage":"unknown","Bottom Termination":"Closed","Number of Circuits":"4","Base Product Number":"1776302","Terminal Block Type":"Eurostyle Terminal Strip","Current Rating (Amps)":"40A","Material - Insulation":"Polyamide (PA66), Nylon 6/6","Operating Temperature":"100°C","Terminal Screw Finish":"Zinc, Non-Hexavalent Chromate","Number of Wire Entries":"8","Terminal Screw Material":"Steel","Material Flammability Rating":"UL94 V-2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.60000","currency":"USD"},{"qty":10,"price":"$4.03200","currency":"USD"},{"qty":25,"price":"$3.92640","currency":"USD"},{"qty":50,"price":"$3.84180","currency":"USD"},{"qty":100,"price":"$3.60960","currency":"USD"},{"qty":250,"price":"$3.58852","currency":"USD"},{"qty":500,"price":"$3.35634","currency":"USD"},{"qty":1000,"price":"$2.99748","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/796754e8e7c7bc8647232ddc6d99c9e1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of TE 1776302-4?","answer":"The pitch is 0.472\" (12.00mm) between terminals, measured centre-to-centre."},{"question":"What wire gauge is compatible with 1776302-4?","answer":"The strip accepts 10-22 AWG wire, covering both heavy power conductors and lighter control wiring."},{"question":"Where can I buy 1776302-4 available via RFQ confirmation?","answer":"This part is active and sourced per RFQ.
