The WAGO 2002-1404 is a 4-wire 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, with support for a cross-section of 4 mm² under specific conditions. The terminal block is blue in colour and features a Push-in CAGE CLAMP® system, allowing for quick and tool-free connection of conductors. The design is intended for mounting on support rails with dimensions 35 x 15 mm and 35 x 7.5 mm, ensuring universal use in various enclosures and control systems. The terminal block is suitable for applications in explosion protection categories Ex e II and Ex i, qualifying it for use in potentially explosive environments.

Applications

The terminal block is used in industrial electrical engineering, particularly in plants operated under explosion protection conditions. It is suitable for connecting wires in control and enclosure cabinets, distribution boxes, and automation technology. Use in areas with increased requirements for electrical safety, such as in the chemical industry or material handling technology, is possible due to its approval for Ex e II and Ex i. The terminal block is suitable for connecting conductors in plants designed according to applicable explosion protection standards.

Functions and Equipment in Detail

The terminal block features a Push-in CAGE CLAMP® system, enabling quick and secure connection of conductors without tools. Connection is achieved by simply inserting the conductor into the terminal channel, where it is held by a spring-loaded contact. The terminal block is designed for a nominal cross-section of 0.25 to 2.5 mm², with support for a cross-section of 4 mm² under specific conditions. Labelling is provided both laterally and centrally, enabling clear identification of wire connections. The blue colour serves visual differentiation and is typical for use in electrical installations.

Technology Explained Simply

The Push-in CAGE CLAMP® system is based on a spring-loaded contact mechanism that securely holds the conductor once inserted into the terminal channel. This system reduces installation time and minimizes the risk of incorrect connections. The terminal block is designed for mounting on support rails with dimensions 35 x 15 mm and 35 x 7.5 mm, enabling universal use in various enclosures. Approval for explosion protection categories Ex e II and Ex i means the terminal block can be used in environments where explosion hazards exist, meeting required safety standards.

Compatibility and Accessories

The terminal block is compatible with various accessories designed to optimize installation and labelling. These include, for example, comb bridges such as the 2002-409/000-006, which enable parallel connection of multiple terminals, and labelling systems such as the 793-5501 Multilabelling System WMB, which allows clear identification of wire connections. Additional compatible accessories include insulation stops (2002-172), Mini-WSB quick labelling systems (248-501/000-024, 248-501/000-012), and end and intermediate plates (2002-1492). Combination with plug-in connector strips such as the 2002-556 or 2002-554 enables flexible expansion of the installation.

Installation and Mounting

Mounting is performed on standard support rails with dimensions 35 x 15 mm and 35 x 7.5 mm. The terminal block is simply clipped onto the rail and locks automatically. Wire connection is tool-free via the Push-in CAGE CLAMP® system. Labelling is done using the integrated labelling fields, arranged both laterally and centrally. Installation is quick and requires no special tools.

Operational Advantages

The terminal block provides quick and secure wire connections, reducing installation time and increasing connection reliability. Approval for explosion protection categories Ex e II and Ex i expands its application in hazardous environments. Universal mounting on various support rails and compatibility with different accessories increase flexibility in planning and executing installations. Clear labelling options support maintenance and fault diagnosis.
