Allen-Bradley 1492-EBL4-B | Blue End Barrier for 1492-L4 and 1492-L4-B Spring-Clamp Terminal Blocks Lot of 44

The 1492-EBL4-B is an essential safety accessory that snaps onto the open side of the last terminal block in a row. Since terminal blocks are manufactured with one side exposed to allow for internal connections, this barrier is necessary to seal the assembly. It ensures that the terminal strip is IP20 finger-safe and provides the electrical insulation required to prevent "creepage" (arcing) between the last block and the metal end anchor or cabinet wall.
