Allen-Bradley 1492-JD3FB24 | 2-Level Fused Terminal Block, 24V DC LED Indicator, Screw Connection Lot of 9

The 1492-JD3FB24 is a "double-decker" terminal block designed to maximize DIN rail efficiency. The top level features a hinged fuse carrier designed for standard $5 \times 20\text{ mm}$ fuses and includes a built-in 24V DC LED that illuminates when the fuse blows. The bottom level is a standard feed-through circuit, typically used for the common/neutral return wire. This allows you to wire both the "hot" protected side and the "return" side of a device using just one terminal block.
