The WAGO 2202-1201 is a 2-wire passage terminal block designed for secure and efficient connection of conductors in industrial applications. The device features a pusher that enables the connection of conductors with a cross-section up to 2.5 mm². The terminal block is equipped with a test opening, allowing for easy and safe inspection of the connection during operation. It is suitable for applications in the Ex e II category, qualifying it for use in potentially explosive environments. The terminal block supports both side and central labeling, ensuring clear identification of connections. Mounting is done on support rails with dimensions 35 x 15 mm and 35 x 7.5 mm, enabling universal use in various enclosures. The connection technology is based on the Push-in CAGE CLAMP® system, which allows for quick and reliable connections without tools. The terminal block is finished in gray color.

Applications
This terminal block is suitable for use in industrial electrical installations, particularly in environments subject to explosion protection category Ex e II. It is appropriate for connecting conductors in enclosures, control systems, and distributors where a secure and durable connection is required. Its use on standard support rails ensures compatibility with a wide range of enclosure configurations.

Functions and Equipment in Detail
The 2-wire passage terminal block 2202-1201 enables the connection of two conductors at a single connection point. The integrated pusher facilitates installation and ensures a secure connection. The test opening allows inspection of the connection during operation without disassembling the terminal block. Labeling options on the side and in the center support clear identification, simplifying maintenance and fault diagnosis. The Push-in CAGE CLAMP® system enables quick and tool-free connections, reducing installation time.

Technology Explained Simply
The Push-in CAGE CLAMP® system operates with a spring-loaded clamping mechanism that automatically secures the conductor once inserted into the terminal block. The pusher serves as an aid to press the conductor securely into the terminal block. The test opening is an additional connection point that allows electrical connection to be checked with a measuring device without opening the terminal block. The protection type Ex e II means the terminal block is suitable for use in areas where explosion hazards exist due to flammable gases or vapors, and meets the requirements for electrical safety.

Compatibility and Accessories
The terminal block is designed for mounting on support rails with dimensions 35 x 15 mm and 35 x 7.5 mm, ensuring high compatibility with common enclosure systems. As accessories, various labeling systems are available, including the WMB multilabeling system in different colors and the Mini-WSB quick labeling system. Additionally, wire end ferrules for different cross-sections (0.5 mm², 0.75 mm², 1 mm², 1.5 mm²) can be used to optimize the connection. Fork bridges and box bridges in various designs enable connection of multiple terminals. Test probes and group label holders support maintenance and identification.

Mounting and Installation
Mounting is done by inserting the terminal block into the support rail, where the shape of the rail secures the block in place. The conductor connection is tool-free via the Push-in CAGE CLAMP® system. The pusher is used to press the conductor securely into the terminal block. Labeling can be done directly on the terminal block, with side and central labeling options enabling flexible identification.

Operational Advantages
The terminal block provides a fast and reliable connection that can be installed without tools. The test opening allows for easy inspection of the connection during operation, simplifying maintenance and fault diagnosis. Compatibility with various support rails and a wide range of accessories increases installation flexibility. The Ex e II approval expands the application range to potentially explosive environments.
