Product details

Three-Circuit PCB Terminal Block, 5.08 mm Pitch

The 282851-3: It accepts 12-30 AWG wire via a rising cage clamp mechanism — the screw pushes a clamp plate down onto the stripped conductor, not the wire itself, so the conductor is held without damage. The green polyamide housing (PA66/Nylon 6/6) is rated UL 94 V-0 for flame resistance inside equipment enclosures. The single-level, vertical orientation means wires enter from the top, perpendicular to the board, which keeps the assembly compact in the z-axis.

0.79 Nm Screw Torque — Why It Matters

The M3 screw has a specified torque of 0.79 Nm (7.0 Lb-In). This is not a suggestion — under-torque leaves the clamp loose, risking a high-resistance joint that heats under load; over-torque strips the brass threads in the PA66 housing. Use a calibrated driver set to that value. The rising cage clamp design gives a gas-tight connection on solid or stranded wire, but only if the screw is tightened to spec.

Interlocking Side Feature for Multi-Position Assemblies

The side interlocking feature lets you snap multiple 282851-3 blocks together side-by-side without gaps. The interlock keeps the assembly rigid during wave soldering and field wiring.

Frequently asked questions

What is the wire range for the 282851-3?

The rising cage clamp accepts 12-30 AWG solid or stranded wire. Use 12 AWG for the full 17.5 A rating; smaller gauges for signal or control circuits.

What is the pitch of the 282851-3?

The pitch is 0.200" (5.08 mm), a standard spacing for industrial terminal blocks. The PCB footprint must match this center-to-center distance between positions.
