Allen-Bradley 1492-L3Q Panel Terminal Block

Allen-Bradley 1492-L3Q Panel Terminal Block is a gray spring-clamp, one-circuit feed-through terminal block designed for through-wiring in control panels. It accepts 2.5 mm² conductors (AWG #30–#12) and provides two connection points on each side to carry a single circuit through the block. As part of the 1492 family, the L3Q footprint is shared by color variants such as L3Q-W (white), L3Q-B (blue), L3Q-BR (brown), and L3Q-G (green), all maintaining the same form factor. The block measures roughly 59.5 mm in length (about 2.34 in), enabling compact wiring within tight panel layouts. This terminal block is commonly used in industrial cabinets to route signals or power between components, offering a reliable, tool-free termination method via spring clamps.
