Allen-Bradley 1492-EB3 Terminal Block End Barrier – Gray, for 1492-W3, W4, and WG4 (Pack of 21)

The 1492-EB3 is a snap-on plastic plate that matches the profile of the 1492-W series terminal blocks. It is strictly used to close off the open side of a terminal block assembly, ensuring that no live parts are exposed. Using an end barrier is required by most electrical codes to maintain the IP20 "finger-safe" rating of a DIN rail assembly.
