Allen-Bradley 1492-JD3-Y | 25A Two-Level Terminal Block, Yellow, 600V, 2.5mm² Screw Connection Lot of 86

The 1492-JD3-Y is a "double-decker" terminal block designed to maximize DIN rail space by stacking two independent circuits vertically. This allows you to terminate twice the number of wires in the same 5.1mm horizontal footprint as a standard block. The yellow color-coding is a critical safety feature, used to warn maintenance personnel that the circuit carries a "foreign voltage" or is part of a system not controlled by the local cabinet's primary disconnect.
