The WAGO 2002-1401 is a 4-conductor pass-through terminal block designed for use in industrial applications. It enables secure and reliable connection of up to four conductors with a cross-section of 0.25 to 2.5 mm² (optionally up to 4 mm²), and is suitable for applications in the Ex e II category. The terminal block is operated using Push-in technology CAGE CLAMP®, allowing for quick and tool-free connection of conductors. The grey version is intended for mounting on support rails with dimensions 35 x 15 mm and 35 x 7.5 mm. Labelling is possible both laterally and centrally, enabling clear identification of connections during operation.

Pass-through terminal block for multiple conductors
The terminal block is designed as a pass-through terminal block, meaning the electrical connection is carried through multiple terminals. This is particularly advantageous in control panels, where multiple conductors need to be connected at one point and simultaneously routed further. The 4-conductor function allows parallel connection of four individual conductors, reducing the number of required terminal blocks and increasing mounting efficiency.

Push-in technology CAGE CLAMP®
The conductors are connected using Push-in technology CAGE CLAMP®, where the conductors are simply inserted into the terminal block. The terminal block automatically grips the conductor and holds it securely. This technology reduces mounting time and minimizes the risk of incorrect connections. The terminal block is designed for conductor cross-sections of 0.25 to 2.5 mm², with an optional extension up to 4 mm², providing high flexibility for use with various cable types.

Ex e II approval
The terminal block is suitable for use in explosive atmospheres in the Ex e II category. This means it meets the requirements for electrical equipment in explosive environments, with the approval ensuring safe operation under defined conditions. The terminal block is therefore suitable for applications in the process industry, chemical industry, or power generation, where higher safety requirements apply.

Support rail mounting
The terminal block is designed for mounting on standard support rails with dimensions 35 x 15 mm and 35 x 7.5 mm. These rails are widely used in industrial electrical engineering and allow modular and structured mounting of components. The terminal block can thus be integrated into existing control panels without requiring additional mounting aids.

Labelling options
The terminal block allows for both lateral and central labelling. This facilitates identification of individual connections during operation and contributes to the transparency of the control panel. Labelling can be done using compatible labelling systems such as the Mini-WSB or WMB system, which are available in the accessories list.

The terminal block is finished in grey, providing good visibility in the control panel and offering a neutral appearance. The colour is part of the product specification and corresponds to the standard design of the WAGO product range.

Compatibility and accessories
The terminal block is compatible with various accessories that extend its functionality. These include, for example, box bridges, comb bridges, plug-in connector strips, and labelling systems. These can be used for parallel connection of multiple terminal blocks, identification, or expansion of connection options. The mentioned accessories are listed in the compatible products section and can be added according to requirements.

Mounting and installation
Mounting is done by simply inserting the terminal block into the support rail. The Push-in connection of conductors requires no tools and can be performed quickly and securely. The terminal block is intended for use in control panels and distribution boxes, where high reliability and ease of maintenance are required.

Operational benefits
The terminal block offers high operational safety through Push-in technology and Ex e II approval. The 4-conductor function reduces the number of required components and simplifies circuit diagram and installation planning. The labelling options increase transparency and facilitate maintenance and fault diagnosis. Compatibility with various accessories allows flexible adaptation to different requirements.
