What the 10 mm pitch buys you at 600 V
The TE Connectivity Buchanan 282838-6 is a 6-position PCB-mount terminal block with a 0.394" (10.00 mm) pitch. That pitch is the key enabler for the 600 V rating — the wide spacing gives you real creepage distance between adjacent terminals, so you can run 600 V circuits without worrying about tracking across the board surface. The green polyamide (PA66) housing carries the interlocking side feature, which lets you snap multiple 6-position blocks together into a longer assembly — useful when your BOM calls for 12, 18, or 24 positions and you want a single mechanical rail instead of separate standoffs.
Wire termination is screw-driven rising cage clamp, accepting 16-30 AWG. The clamp material is brass with nickel plating; the screw is M3 brass, nickel-plated, torqued to 0.68 Nm (6 Lb-In). The rising cage clamp pulls the wire into a gas-tight joint against the tin-plated brass contact — no cold flow over time, no need for ferrules on stranded wire. The 16-30 AWG range covers power feeds (16 AWG) down to signal-level conductors (30 AWG), so this block handles mixed-gauge harnesses in the same assembly.
Current and voltage — what the numbers mean
The 13.5 A is a per-position current limit. The single-level orientation (horizontal with board) keeps the wire entry parallel to the PCB.
