WAGO 281-309 Terminal Block End Barriers DIN Rail Mount

The WAGO 281-309 Terminal Block End Barrier is an insulating accessory that provides end-of-row protection, circuit separation, and electrical isolation for DIN-rail-mounted terminal block assemblies used in industrial control and power distribution systems. Designed for DIN rail terminal block systems and compatible with Wago terminal block assemblies, it uses industrial-grade insulating material to support organized control panel layouts, clearer circuit identification, and safer wiring in PLC cabinets, machine control panels, manufacturing equipment, process automation systems, and electrical enclosures. It delivers terminal block separation and electrical isolation to maintain dedicated spaces between terminal rows for power, signal, and control wiring, helping maintenance and panel construction in industrial automation and electrical distribution panels.
