The WAGO 280-402 is an insulated bridge, specifically designed for use in terminal block constructions. It serves as a cross-bridge between adjacent terminals to establish electrical connections within a terminal module, without requiring additional conductors or connecting pieces. The grey colouring supports visual differentiation within control systems and facilitates maintenance and servicing. The bridge is designed for use in industrial electrical installations, where a reliable and durable electrical connection is required.

Applications

The bridge is used in enclosures, control systems, and distribution boxes where multiple terminals are arranged in a row and an electrical connection between them must be established. It is particularly suitable for applications in automation technology, machine and plant engineering, as well as in electrical installations. The bridge is used in combination with WAGO terminal blocks, especially with models that support cross-bridging. The insulation ensures that no unintended short circuits occur between adjacent terminals, increasing the safety of the installation.

Functions and Features in Detail

The bridge enables a direct electrical connection between two adjacent terminals, while the insulation ensures electrical separation from other terminals in the module. The grey colour serves as a visual identifier and supports clarity during assembly and maintenance. The design allows it to be simply inserted and secured in the corresponding terminal without requiring additional tools or mounting aids. The connection is mechanically stable and prevents loosening or shifting during operation.

Technology Explained Simply

The bridge consists of an insulated conductor piece that is inserted into the terminal, establishing an electrical connection between two adjacent terminals. The insulation protects against short circuits and increases electrical safety. The maximum permissible cross-sectional area is 2.5 mm², which is sufficient for a wide range of conductors in industrial electrical engineering. The permissible current load is 24 A, which is adequate for many standard applications in control technology and power distribution. The design is intended for use in terminal modules that support cross-bridging, enabling a quick and secure connection without additional connecting wires.

Compatibility and Accessories

The bridge is specifically developed for use with WAGO terminal blocks, particularly with models that support cross-bridging. It is compatible with terminals that allow horizontal connections between adjacent terminals.

Mounting and Installation

Mounting is done by simply inserting the bridge into the designated position within the terminal. No additional fastening or tools are required. The terminal itself provides the mechanical fixation of the bridge. Installation takes place during the mounting of the terminal row, with the bridge positioned according to the desired electrical connection. The connection becomes effective immediately after insertion and requires no additional steps to activate.

Advantages in Operation

The bridge reduces the number of required connecting wires, shortening assembly time and reducing the risk of errors. The insulation increases safety and prevents unintended electrical contacts. The grey colour supports clarity in complex control systems. Mechanical stability ensures a durable connection, even under mechanical stress. Use in combination with WAGO terminals enables a standardised and reliable installation in industrial applications.
