Allen-Bradley 1492-WG4 4-Position Terminal Block

Allen-Bradley 1492-WG4 is a four-position IEC terminal block designed for space-saving, single-circuit grounding in control panels. This screw-connection block mounts on a standard DIN rail and provides four earth-grounding points in a compact footprint. It accepts conductor sizes of 4 mm² (AWG 22–10) or 2.5 mm² (AWG 22–12), giving flexibility for mixed grounding wiring. The standardized Green/Yellow Stripe marks the ground terminal, ensuring quick identification in complex wiring. Its compact dimensions are about 48 mm long, 35 mm wide, and roughly 6 mm high above the mounting rail, making it suited for dense panel layouts. As part of Rockwell Automation’s 1492-WG family, the 1492-WG4 offers reliable, compliant grounding distribution for motors, sensors, and I/O modules in industrial automation applications.
