It is designed for through-hole mounting on a PCB, where it provides a field-wiring interface for power or signal connections that need a secure, serviceable termination. The 0.375\" (9.53mm) pitch gives enough spacing for the 300V rating without crowding the board layout. Rated 15A per circuit, this barrier strip can handle a moderate power load — think a small motor, a heater element, or a power supply output. The 300V rating covers most low-voltage industrial and commercial control circuits. The 3-wall (tri) barrier design isolates each terminal from its neighbour, reducing the risk of accidental shorts from a stray wire strand. The screw with captive plate means the pressure plate stays with the screw when backed off — no loose parts to drop into the enclosure. Wire acceptance is 14-22 AWG, which covers common control and power wiring. The nickel-plated steel screw resists corrosion in humid environments. The operating temperature of 120°C allows use in warm cabinets or near heat sources without derating. Termination is straightforward: strip the wire to the recommended length, insert into the clamp, and tighten the screw. The captive plate presses the wire against the current bar — no crimp tool or ferrule required. The through-hole mounting gives a strong mechanical anchor compared to surface-mount. The included cover snaps over the screw tops for touch protection after wiring. The 2-circuit 1546833-2 is the same pitch (0.375\"), same current and voltage ratings, same termination style as the single-circuit member of the Buchanan series. The difference is purely the circuit count — 2 circuits vs 1 — which determines how many independent wires terminate on one block. If your BOM calls for two wires on a shared common, the 2-circuit version is the fit; if you need isolation per wire, you would use two single-circuit blocks.","metaTitle":"TE Connectivity 1546833-2 Buchanan Barrier Strip, 2 Circuits","metaDescription":"TE Connectivity Buchanan 1546833-2 barrier strip, 2 circuits, 0.375\" pitch, 15A, 300V, 14-22 AWG, UL94 V-0.
