The three-wall (tri) barrier construction isolates each terminal position, preventing accidental shorting between adjacent circuits. Rated 15A at 300V, this strip handles moderate power distribution in control panels, HVAC equipment, lighting ballasts, and industrial machinery where a screw-terminal interface is preferred over a crimp connector. Wire gauge acceptance is 14-22 AWG, covering solid and stranded copper — the screw and captive plate clamp the conductor without a separate ferrule. The terminal screw is steel with a nickel finish, which resists corrosion in humid panel environments. ## Circuit Count Selection The 1546833-3 carries 3 circuits. The same Buchanan series also offers a 2-circuit (1546833-2) and a 4-circuit (1546833-4) variant at the same 0.375\" pitch, 15A rating, and 300V rating. Pick the circuit count that matches the number of field-wired conductors in your BOM — the footprint on the PCB scales linearly with position count, so a 4-circuit strip occupies one extra position width over this 3-circuit version. A related Buchanan strip, the 1546927-3, also has 3 circuits but uses a tighter 0.325\" (8.26mm) pitch. If board space is tight, that narrower pitch saves 0.050\" per position, but the terminal spacing is closer — verify your wire bundle clearance before swapping.","metaTitle":"TE Buchanan 1546833-3 Barrier Strip, 3 Circuit, 0.375\" Pitch","metaDescription":"TE Connectivity Buchanan 1546833-3 barrier block, 3 circuits, 0.375\" pitch, 15A, 300V.
