Two-Position PCB Terminal Block for Control Wiring
It terminates 14-30 AWG wire via a screw-driven rising cage clamp — the cage lifts to trap the conductor against the current bar, not the screw tip, so the wire isn't crushed or cold-flowed over time. The 3.81 mm pitch gives enough space between positions for a standard screwdriver without crowding adjacent terminations, and the green PA66 housing is rated for continuous use inside equipment enclosures.
Wiring and Torque Specs for the Rising Cage Clamp
The rising cage clamp accepts solid or stranded wire from 14 AWG down to 30 AWG. The M3 screw is tightened to 0.25 Nm (2.2 Lb-In) — that's about a quarter turn past finger-tight on a standard terminal screwdriver. Over-torquing strips the brass threads; under-torquing leaves the cage not fully lifted against the wire. The clamp and screw are brass with nickel plating, and the contact bar is brass with tin plating — the tin surface mates well with copper wire and resists galvanic corrosion in indoor environments.
Ganging Multiple Blocks with the Interlocking Side
The interlocking side feature lets you snap adjacent blocks together into a continuous strip without a separate end barrier or DIN rail adapter.
How the 2-Position Compares to the 7-Position Sibling
The 284392-7 is the same Buchanan series, same 3.81 mm pitch, same 12 A / 300 V rating, same green housing and rising cage clamp — but with 7 positions per level instead of 2. Both use the same M3 screw torque and accept the same 14-30 AWG wire range.
