The green polyamide housing (PA66) is standard for this class; it carries the UL94 V-0 flame rating typical of equipment inside an enclosure.
The rising cage clamp lifts to accept stripped wire, then clamps down as the M3 screw is torqued to 0.68 Nm (6 Lb-In). It handles 16-30 AWG — solid or stranded — without damaging the conductor. The brass clamp and screw are nickel-plated, the contact is tin-plated brass, so the current path stays corrosion-resistant in a cabinet environment. This is a field-termination block, not a crimp-and-insert connector; you land the wire directly under the screw.
Interlocking and Ganging
The side interlocking feature lets you snap multiple 1-284093-2 blocks together side-by-side to build a wider terminal strip — no separate jumper or bridging piece needed for the mechanical assembly. The electrical connection between ganged blocks still requires a wire jumper or bus bar across the screw clamps; the interlock is mechanical only, for alignment and vibration resistance on the PCB.
Current and Voltage Ratings — What They Mean
Rated 13.5 A per position at 300 V. That 13.5 A is the continuous current through the rising cage clamp and tin-plated brass contact — sized for power distribution on a control board, not signal-level duty. Derate above the ambient temperature the block sees inside the enclosure; the PA66 housing limits the continuous temperature rise.
