The Siemens 8WA1898 is a screw-mounted connecting bar designed to bridge 10 compatible size 2.5 terminal blocks. Part of the ALPHA FIX terminal block range, this link rail establishes a common electrical connection across multiple terminals, helping to simplify wiring arrangements in industrial control cabinets and distribution assemblies.
Its screw-fastened design provides secure attachment to the terminal assembly, making it suitable for applications requiring several connection points to share the same potential. The 8WA1898 is uninsulated and has no integral touch protection, so these characteristics should be considered when selecting components for the installation.

What is this connecting bar used for?
This connecting bar creates a common electrical connection across compatible terminal blocks. It allows several terminals to share the same potential without individual wire links between each terminal.
How many terminals can the connecting bar bridge?
The bar is designed to bridge 10 terminals, making it suitable for grouped connections within a compatible terminal assembly.
Which terminal range is this connecting bar designed for?
The 8WA1898 is an accessory for the ALPHA FIX terminal block range and is specified for terminal size 2.5. Compatibility should be checked against the exact terminal block reference rather than terminal size alone.
How is the connecting bar secured?
The connecting bar uses screw fastening to secure it to the compatible terminal assembly. It is not a push-in bridging accessory.
Is the connecting bar insulated?
No. This is an uninsulated link rail, and the product specification also lists no integrated touch protection. These characteristics should be considered when selecting accessories for the complete terminal assembly.
Is this a terminal block or a terminal block accessory?
It is a terminal block accessory, described as a connecting bar or link rail. It bridges existing compatible terminals rather than serving as a standalone terminal block for connecting conductors.
What is the net weight of the connecting bar?
The January 2025 product data sheet lists a net weight of 13 g for the 8WA1898. Earlier data sheets list 12.7 g.
