Insulation

The article 284-402 from WAGO is an insulated cross bridge used in connection technology for secure and reliable electrical connection of conductors in terminal blocks. It serves as a bridge between adjacent terminals, enabling parallel current flow without additional wiring. The bridge is gray in color and designed for use in industrial plants and electrical installations where high mechanical and electrical load capacity is required.

Bridge

The bridge is a component for electrical connection of multiple terminals in a row. It is used in terminal block systems to connect multiple connection points, enabling a common power supply or a common grounding point. The insulated design protects against short circuits and increases operational safety.

Insulation

The insulation of the bridge ensures that the electrical connection occurs only at the designated connection points. This prevents unintended contact with adjacent conductors or terminals. The insulation is firmly integrated and provides high protection against electrical hazards, especially in environments with high mechanical stress or limited space.

Cross Bridge

As a cross bridge, the component is designed to be mounted perpendicular to the longitudinal axis of the terminal row. This enables direct connection between two adjacent terminals, simplifying wiring and reducing installation time. The design is compatible with the corresponding terminal blocks in the WAGO product range.

Rated Current and Cross-Section

The bridge is rated for a nominal current of 57 A, making it suitable for medium to high loads in industrial applications. The maximum conductor cross-section is 10 mm², allowing use with thicker cables. These values ensure safe and stable current transmission under load.

Color and Material

The bridge is gray in color, distinguishing it visually from other components and enabling easy identification in the enclosure. The color serves primarily for visual identification and does not affect functionality.

Applications

The bridge is used in electrical installations, automation technology, and industrial control systems. It is particularly useful in enclosures where multiple terminals need to be connected without requiring additional wiring. The insulated design also makes it suitable for applications requiring high electrical safety.

Compatibility and Accessories

The bridge 284-402 is specifically designed for use with terminal blocks in the WAGO product range. It is designed as a cross bridge and fits the standard dimensions of the terminals.

Mounting and Installation

Mounting is done by simply inserting the bridge into the designated connection points of the terminal blocks. No additional tools or mounting aids are required. The connection is mechanically stable and secured by the shape of the bridge and its fit within the terminal. Installation is done without additional wiring, reducing installation time.

Installation follows general guidelines for terminal block systems.

Operational Advantages

The bridge reduces the number of required connecting wires, simplifying installation and reducing error rates. The insulated design increases safety and prevents short circuits. The high current capacity of 57 A and support for 10 mm² conductor cross-section make it suitable for a wide range of industrial applications. The gray color facilitates visual differentiation in the enclosure.
