Insulation

The product WAGO 280-490 is a bridge, specifically designed for use in terminal blocks in industrial applications. It serves as an insulated bridging cam and enables the electrical connection of multiple terminals in a row. The configuration is 10-way, meaning it simultaneously connects ten adjacent terminals. The component is grey, which is typical for WAGO's product range and allows for clear visual differentiation from other components. The insulation ensures safe separation of individual contacts, preventing short circuits.

Applications

The bridge 280-490 is used in industrial electrical engineering, particularly in control panels, control systems, and distributors, where a secure and reliable electrical connection of multiple terminals is required. It is suitable for applications demanding high contact quality and mechanical stability, such as in automation technology or manufacturing industry. The insulated design makes it especially suitable for installations where galvanic separation between individual terminals is necessary to avoid interference or dangerous voltage transmission.

Functions and Features in Detail

The bridge connects ten terminals in a row via a common electrical path. The insulated construction ensures that individual contacts are not electrically connected to each other, but only connected via the bridge. This is important to maintain the function of individual terminals while enabling common power supply or signal transmission. The grey colour serves as a visual identifier and supports quick identification in the enclosure.

Technology Explained Simply

The bridging is achieved through a metallic connection that runs over the insulated contacts of the terminals. The insulation prevents unintended electrical connections between individual terminals, which is particularly important in complex circuits. The construction is robust and designed for use in industrial environments.

Compatibility and Accessories

The bridge 280-490 is specifically designed for use with WAGO terminal blocks. It is compatible with corresponding terminals in the WAGO product range, particularly with models that support bridging functions. As suitable accessory, the actuation tool 280-440 is offered, which facilitates easy and secure installation of the bridge into the terminal row. The tool simplifies insertion and removal of the bridge, especially in tight enclosures or during frequent maintenance work.

Installation and Mounting

Mounting is done by simply inserting the bridge into the corresponding terminals in the row. The bridge is inserted into the designated openings of the terminals, with the insulation separating individual contacts. The actuation tool 280-440 can be used to assist with installation, ensuring secure and precise placement. Installation requires no additional tools, with mechanical stability ensured by the bridge’s shape and fit within the terminals.

Operational Advantages

Using the bridge 280-490 reduces the number of required connections and simplifies wiring. The insulated design increases safety and prevents unintended electrical contacts. The 10-way bridging enables efficient wiring, especially in larger installations, and reduces installation time. The robust construction ensures long service life and reliable performance under industrial conditions. The grey colour supports visual orientation in the enclosure and facilitates maintenance.
