The 1546074-5: The rising cage clamp — tightened with an M3 screw to 0.79 Nm (7.0 Lb-In) — grips the conductor directly, making a gas-tight connection that holds up under thermal cycling and vibration in industrial control panels, power supplies, and building automation gear.
Accepts 12 to 30 AWG — solid or stranded — into the rising cage clamp. The brass clamp and screw are nickel-plated; the contact area is tin-plated brass. The M3 screw torque spec of 0.79 Nm (7.0 Lb-In) is the number to hit: under-torque risks a loose connection, over-torque can strip the nylon threads.
Ganging Multiple Blocks
The interlocking side feature lets you snap adjacent blocks together without extra brackets or rails. Each block is 1 level, 5 positions; stacking them side by side builds a multi-position strip at the same 5.08 mm pitch. No alignment jig needed — the interlock keys keep the pitch consistent across the assembly.
