The 1-282856-1: The green polyamide (PA66) housing carries the UL94 V-0 flame rating typical for equipment inside an enclosure.
The 12-30 AWG wire range accepts both heavy 12 AWG power conductors and fine 30 AWG signal wires, reducing the need for multiple block types on the same board. The rising cage clamp termination, driven by an M3 screw torqued to 0.79 Nm (7.0 Lb-In), grips the full conductor cross-section without cold flow — a reliable termination for field wiring where vibration is present. Brass contacts are tin-plated, adequate for the rated current in indoor environments; the brass nickel-plated clamp and screw resist corrosion in the termination zone.
Interlocking and Ganging
The interlocking (side) feature allows multiple 1-282856-1 blocks to be snapped together side-by-side without gaps, forming a wider terminal strip from standard modules. This is useful when you need more than 11 positions on a single board — just add another block and the interlocking key keeps the assembly aligned. The single-level design means all 11 positions are on one row, so the board layout stays simple.
