Allen-Bradley 1492-SP3 | Terminal Block Separation Plate, for 1492-W3 and W4 Series Lot of 22

The 1492-SP3 is a specialized insulation and partition plate designed for use with Bulletin 1492-W IEC terminal blocks (specifically the W3 and W4 models). Unlike a thick "End Barrier," this Separation Plate is ultra-thin ($0.35\text{ mm}$), designed to provide electrical isolation between adjacent circuits without significantly increasing the width of the terminal strip. It is an essential component when separating different voltage levels or grouping specific control signals on a single DIN rail.
