It accepts 14-22 AWG wire through a dual-wall barrier with screw top termination and a closed bottom, rated 25A at 300V. The 25A per-circuit current rating and 300V voltage rating cover most industrial control and lighting circuits. The 0.437\" pitch provides creepage between adjacent circuits for the 300V rating. The dual-wall barrier reduces accidental shorting during wiring. ## Wire Range and Termination — Screw Clamp, Closed Bottom The top termination uses steel screws with a nickel finish, clamping 14-22 AWG solid or stranded wire. The closed bottom means the screw terminal does not pass through the block — the wire is trapped between the screw and the current bar inside the housing. This is a standard screw-clamp barrier block: reliable for permanent installations, but the screws can back off under thermal cycling if not torqued to spec. The flange on each end allows bolting the block to a chassis or panel, providing strain relief for the incoming wires.","metaTitle":"TE Connectivity Buchanan 1546670-3 Barrier Strip, 3 Circuits","metaDescription":"TE Connectivity Buchanan 1546670-3 barrier strip, 3 circuits, 0.437\" pitch, 25A, 300V, UL94 V-0, 14-22 AWG, black.
