It mounts through-hole and accepts 18-26 AWG wire via a screw clamp with a leaf spring and wire guard — the guard prevents the screw from cutting into the conductor strands, a common failure in cheaper blocks. Rated 7 A at 250 V, it suits control signals, sensor inputs, and low-power distribution inside industrial cabinets, HVAC panels, or lighting fixtures. The blue housing helps identify it as a neutral or specific circuit in multi-block assemblies. ## Torque and termination — what the screw spec means in the field The M2.6 screw has a factory torque spec of 0.28 Nm (2.5 Lb-In) — that's the sweet spot for clamping 18-26 AWG solid or stranded wire without stripping the threads or crushing the conductor. The leaf spring maintains pressure as the wire relaxes under thermal cycling, and the wire guard keeps the strands contained under the screw head. Clamp material is steel, stainless; the screw is steel with galvanized-chromate plating for corrosion resistance in humid environments. The contact is brass with copper-tin plating — adequate for the current rating and typical cycle count in a terminal block application. ## Side interlocking and board layout This block features side interlocking, so you can snap multiple 1776275-3 units together to form a longer strip without extra hardware. The polyamide (PA66) housing is rated for flame resistance.","metaTitle":"1776275-3 TE Connectivity Buchanan 3 Position Terminal","metaDescription":"1776275-3 TE Connectivity Buchanan terminal block, 3 positions, 3.50mm pitch, 7 A, 250 V, screw termination, side entry, blue.
