Allen-Bradley 1492-JD4-B | 35A Two-Level Terminal Block, Blue, 600V, Lot of 18

The 1492-JD4-B is a "double-decker" terminal block that allows for two independent circuits to be wired within a single 6.1mm footprint. This design effectively doubles the wiring density on a DIN rail, making it ideal for compact control cabinets. The blue color-coding is a standard industrial convention used to distinguish neutral connections or low-energy circuits in hazardous locations.
