The WAGO 2002-1407 is a 4-conductor protective earth terminal, specifically designed for use in electrical installations with protective earth connections. It is rated for cross-sections from 0.25 to 2.5 mm², with a maximum cross-section of 4 mm² considered under special requirements. The terminal is finished in green-yellow, the international identification colour for protective earth conductors, and enables a secure and reliable connection of protective earth conductors in industrial and commercial electrical installations. The connection technology is based on the Push-in CAGE CLAMP® system, which allows for quick and tool-free installation of conductors, where the conductor is inserted into the terminal by pressure and secured by an integrated clamping mechanism.

Applications

The terminal is suitable for applications in the Ex e II category, qualifying it for use in potentially explosive areas with low explosion probability. It is designed for mounting on standard support rails with dimensions 35 x 15 mm and 35 x 7.5 mm, enabling universal use in enclosures and distribution boxes. The side and central labelling options support clear identification of connections, facilitating maintenance and fault diagnosis.

Functions and Equipment in Detail

The 4-conductor design allows the connection of up to four individual conductors at a single terminal, reducing the number of required components and increasing installation efficiency. The terminal is equipped with a Push-in CAGE CLAMP® system, enabling quick and secure connections without additional tools. The green-yellow colouring corresponds to the standard for protective earth conductors and ensures unambiguous identification in the electrical system.

Technology Explained Simply

The Push-in CAGE CLAMP® system operates on the principle of elastic clamping: the conductor is inserted into an opening, where an integrated clamping mechanism automatically secures it. This system reduces installation time and minimizes the risk of contact errors. The terminal is rated for cross-sections from 0.25 to 2.5 mm², with the 4 mm² value interpreted as the maximum under special requirements. The green-yellow colouring is the international identification colour for protective earth conductors and complies with DIN VDE 0100-510 regulations.

Compatibility and Accessories

The terminal is compatible with various accessories that extend its functionality. These include, for example, insulated bridges such as the 2002-406/020-000 or 2002-423, which enable connections between multiple terminals. Labelling systems such as the Mini-WSB (e.g. 248-501/000-017) or labelling adapters (e.g. 2002-161) can also be used to clearly identify the terminal. Mounting is performed on support rails with dimensions 35 x 15 mm and 35 x 7.5 mm, which are standard in industry.

Installation and Mounting

Mounting is achieved by simply hanging the terminal onto the support rail. Conductor connections are made tool-free via the Push-in method: the conductor is inserted into the terminal and automatically secured by the integrated clamping mechanism. The side and central labelling options allow for clear identification of connections, simplifying maintenance and servicing.

Operational Advantages

The terminal provides a reliable and secure connection for protective earth conductors, ensuring electrical safety. The Push-in technology reduces installation time and minimizes the risk of errors. Compatibility with standard support rails and various accessories enables flexible integration into existing systems. The green-yellow colouring supports unambiguous identification of the protective earth conductor within the system.

The terminal is suitable for use in installations according to Ex e II, enabling application in potentially explosive areas with low explosion probability. The use of protective earth terminals is necessary in electrical installations to ensure the safety of the system and personnel. The terminal is rated for cross-sections from 0.25 to 2.5 mm², with a maximum cross-section of 4 mm² considered under special requirements. The green-yellow colouring corresponds to the international identification colour for protective earth conductors and is therefore clearly identifiable.
