Allen-Bradley 1492-W4-B | 30A Feed-Through Terminal Block, 600V, Blue (Neutral/IS), 4mm² Screw Connection Lot of 5

The 1492-W4-B is a single-level, feed-through terminal block from Allen-Bradley’s "Space-Saver" series. It offers the exact same mechanical specifications as the standard gray 1492-W4 but features a high-visibility Blue housing. This color-coding is essential for panel safety and organization, allowing technicians to quickly distinguish neutral or low-energy signal wires from "hot" power lines. It utilizes a high-torque screw-clamp connection that ensures gas-tight, vibration-proof wiring.
