The WAGO 2002-1207 is a 2-conductor protective earth terminal with a maximum cross-section of 2.5 mm², specifically designed for use in electrical installations complying with the protection type Ex e II requirements. The device is designed for mounting on standard support rails with dimensions 35 x 15 mm and 35 x 7.5 mm, enabling a secure and reliable connection of protective earth conductors in industrial and operational technical installations. The terminal is finished in green-yellow, which corresponds to the international marking for protective earth conductors and ensures clear identification within the enclosure.

Applications

The terminal is intended for use in electrical installations operating under protection type Ex e II (simple explosion protection for non-flammable gases and vapours). This includes installations in areas with increased explosion risk, such as in the chemical industry, petrochemicals, or processing industries. Use in such environments requires a special design that minimizes the risk of spark generation or elevated temperature. The terminal is therefore suitable for applications where electrical safety and compliance with explosion protection regulations are critical.

Functions and Equipment in Detail

The WAGO 2002-1207 features Push-in CAGE CLAMP® technology, enabling quick and secure connections without tools. Cables are simply inserted into the terminal, where the integrated clamping mechanism automatically generates the required clamping pressure. The terminal is designed for conductor cross-sections from 0.25 to 2.5 mm², with a maximum capacity of 4 mm² possible in certain applications. The side and central labelling allows for clear identification of connections, facilitating maintenance and servicing within the enclosure. The green-yellow colouring corresponds to the international standard for protective earth conductors and ensures clear visual distinction.

Technology Explained Simply

The Push-in CAGE CLAMP® technology is based on a mechanical clamping mechanism activated by inserting the cable. The cable cross-section is held by a clamping jaw that automatically adjusts to ensure a secure connection. The terminal is designed for mounting on standard support rails, enabling easy integration into existing enclosure constructions. Protection type Ex e II means the terminal is suitable for use in potentially explosive environments, where the risk of explosion from electrical sparks or elevated temperatures must be minimized. The terminal meets specific requirements regarding design and material selection for this purpose.

Compatibility and Accessories

The terminal is compatible with standard support rails of dimensions 35 x 15 mm and 35 x 7.5 mm. Suitable accessories include various labelling systems such as the WMB multi-labelling system (e.g. 793-5501/000-006) or inline labels (e.g. 2009-115), enabling individual identification of connections. Additionally, various bridges (e.g. 2002-478, 2002-413) and cover profiles (e.g. 709-156) are available, enhancing functionality and safety within the enclosure. Plug-in connector strips such as 2002-558 or 2002-559 can be used to extend the connection structure.

Mounting and Installation

Mounting is achieved by simply hanging the terminal onto the support rail. The Push-in technology allows connecting conductors without tools, reducing installation time. Cables are inserted into the designated openings, where the clamping mechanism automatically generates the required clamping pressure. Labelling is done either centrally or laterally, depending on the installation requirements. The terminal is designed for use in enclosures complying with the requirements of protection type Ex e II.

Operational Advantages

The terminal provides a reliable and secure connection for protective earth conductors used in potentially explosive areas. The Push-in technology reduces installation time and minimizes error sources. Clear labelling and distinct colouring facilitate maintenance and servicing. Compatibility with standard support rails and various accessories enables flexible integration into existing systems. Compliance with protection type Ex e II ensures safety in sensitive applications.
