Allen-Bradley 1492-JG4 Ground Terminal Block – 4mm² (12 AWG), Green/Yellow (Lot of 4)

The 1492-JG4 is a high-quality grounding terminal block that features a metallic foot designed to "bite" onto the DIN rail, effectively using the rail as a common ground bus. This eliminates the need for a separate ground wire between every terminal and provides a secure, low-impedance path to earth.
