The green polyamide (PA66) housing carries a single level of positions rated for 12 A at 300 V. Wire range accepts 14-30 AWG, and the M3 screw has a specified torque of 0.25 Nm (2.2 Lb-In) — torque it, then scan it, because a loose joint in a screw-clamp block runs hot under load. The side interlocking feature lets multiple blocks key together without extra hardware, useful for building multi-pole terminal strips on a PCB. Wire termination uses a rising cage clamp: strip the wire, insert into the clamp opening, and tighten the M3 screw to 0.25 Nm. The clamp and screw are brass with nickel plating; the contact surface is brass with tin plating. Mating orientation is horizontal with the board — wires enter from the side, parallel to the PCB. The through-hole mounting pins solder into the board; the 3.50 mm pitch matches standard terminal block footprints.","metaTitle":"TE Buchanan 284391-4 Terminal Block, 4 Pos, 3.5mm, 12A","metaDescription":"TE Connectivity Buchanan 284391-4 4-position PCB terminal block, 3.50mm pitch, 12 A, 300 V, side-entry screw clamp.
