It uses a screw-actuated rising cage clamp — the clamp lifts to trap the conductor against the bus bar, giving a gas-tight connection that doesn't cold-flow stranded wire over time. 24 A per position is the block's rated current at the stated voltage and temperature. That figure assumes the full conductor cross-section fills the clamp and the ambient stays within the polyamide housing's operating range. For a 13-position block carrying 24 A on every circuit, the total bus-bar current sums to 312 A — the limiting factor is the PCB trace width and the temperature rise inside the enclosure, not the block itself. The 300 V rating covers most industrial control and lighting circuits; for higher-voltage buswork you'd step up to the Buchanan 9.52 mm pitch series. ## Wire Termination and Installation The rising cage clamp accepts 12 to 30 AWG wire. The screw torque spec is 0.79 Nm (7.0 Lb-In) — over-torquing strips the M3 brass screw or cracks the PA66 housing. The clamp and screw are both brass with nickel plating; the contact surface on the bus bar is brass with tin plating. Tin plating is standard for power terminations — it mates well with tinned or bare copper wire and doesn't require gold for corrosion protection in a dry indoor panel. The interlocking side feature lets you gang multiple blocks side-by-side on the same rail without gaps — useful when a 13-position block isn't enough and you need a continuous terminal strip. It's a current-production Buchanan terminal block, sourced through the standard TE distribution channel. For BOM matching, the pitch, position count, and side-entry orientation are the fixed parameters; colour is the only variable across the -1, -2, and -3 suffixes in this family. ## Comparing 1-282856-3 to 1-282856-2 The 1-282856-2 is the same Buchanan 5.00 mm pitch, side-entry, 13-position terminal block in a different housing colour. The -3 is green; the -2 is the standard black/grey Buchanan colour. All electrical ratings (24 A, 300 V), wire range (12-30 AWG), and mechanical specs (torque, screw thread, cage clamp) are identical. The colour difference is cosmetic — pick the one that matches your panel's wire-colour coding or your BOM's existing colour callout. No functional or footprint difference exists between the two.","metaTitle":"1-282856-3 TE Buchanan Terminal Block, 13 Pos, 5mm, 24A","metaDescription":"TE Connectivity Buchanan 1-282856-3 terminal block, 13 positions, 5.00 mm pitch, 24 A, 300 V.
