What the 10 mm pitch and 24 A rating mean for a panel layout
The TE Connectivity Buchanan 282858-6 is a 6-position PCB-mount terminal block with a 0.394" (10.00mm) pitch — wide enough that each pole carries its own clearance zone on the board, so routing a 24 A trace between adjacent terminals is straightforward without creepage concerns. The 24 A at 600 V rating puts this in the power distribution class: it handles branch-circuit loads inside an industrial control cabinet, not signal-level wiring.
Wire termination and clamping — what the M3 screw and 0.79 Nm torque deliver
Termination is a screw-actuated rising cage clamp. The M3 screw drives a brass-nickel-plated clamp that pulls the wire against the current bar. The specified torque of 0.79 Nm (7.0 Lb-In) is the tightening target.
Interlocking side feature and multi-pole assembly
The interlocking (side) feature allows multiple 282858-6 blocks to be keyed together side-by-side without a separate jumper bar or end bracket. This is the standard Buchanan method for building a multi-pole strip from single-level blocks — the side interlocks align the poles and prevent the assembly from spreading under screw torque. For a 6-position block, the interlock is already integrated; adding a second block gives 12 positions at the same 10.00 mm pitch.
Active lifecycle and sourcing posture
This is a current-catalog Buchanan part, not a legacy phase-out.
