The WAGO 826-163 is a 3-pole passage terminal block designed for use in industrial electrical installations. It enables secure and reliable connection of conductors in the cross-section range of 0.08 to 4 mm². The terminal block is finished in grey and features a pitch of 7 mm, ensuring compatible mounting in standard plug-in rails and enclosures. The delivery includes the terminal block itself, an end plate, and a locking cap, which contribute to secure fixation and protection of the terminal.

Applications
This terminal block is suitable for use in enclosures, distribution boxes, and other electrical distribution systems where a stable and durable connection between conductors is required. It is particularly suited for applications in automation technology, machine building, and building automation, where high mechanical load capacity and electrical reliability are required. Its use in industrial electrical engineering is supported by its robust construction and specific design for conductor cross-sections from 0.08 to 4 mm².

Functions and Equipment in Detail
The WAGO 826-163 is designed as a passage terminal, meaning it is intended for connecting conductors on the front side as well as for passing conductors through the rear side. The integrated end plate ensures proper termination of the terminal strip, while the locking cap secures the terminal against unintended loosening. The terminal is suitable for use with wire end ferrules available in the range of 0.5 to 2.5 mm², with the exact selection of the ferrule depending on the conductor cross-section and requirements. Using wire end ferrules improves contact quality and reduces the risk of contact faults.

Technology Explained Simply
The terminal operates on the principle of a screw terminal with an integrated spring mechanism, ensuring a secure and durable connection. The spring maintains pressure on the connection, ensuring a stable connection even under vibration or mechanical stress. The 7 mm pitch corresponds to the standard in industrial electrical engineering and allows mounting in standard plug-in rails. The grey colour is typical for industrial terminals and aids in visual differentiation from other components. The terminal is designed for conductor cross-sections from 0.08 to 4 mm², enabling broad applicability from fine control wiring to heavier power supply lines.

Compatibility and Accessories
The terminal block is compatible with various wire end ferrules available in the range, including models for 0.5 mm², 0.75 mm², 1 mm², 1.5 mm², and 2.5 mm², some with or without plastic collars. Using ferrules with plastic collars can improve insulation of conductor ends and reduce the risk of short circuits. Additionally, labelling strips (e.g. 210-332/700-103) and test plugs (e.g. 210-136) are available to facilitate maintenance and identification of connections. Operating tools such as models 210-720 or 210-657 support the installation and removal of terminals.

Mounting and Installation
Mounting is performed in standard plug-in rails with a 7 mm pitch. The terminal is inserted into the rail and secured with the locking cap. The connection conductors are inserted into the terminal, with the use of wire end ferrules recommended to ensure optimal contact surface. The end plate is mounted at the end of the strip to ensure proper termination. Installation requires no additional tools, although operating tools may be used optionally for support.

Advantages in Operation
The WAGO 826-163 offers high mechanical stability and electrical reliability, making it suitable for use in demanding industrial environments. The integrated locking cap and end plate enhance safety and prevent unintended loosening of the terminal. Compatibility with various wire end ferrules allows flexible adaptation to different conductor cross-sections. The robust construction and standardised mounting facilitate maintenance and replacement of components.
