Product type	Fixed bridge

The Fixed Bridge FBRN 10-4 N from Phoenix Contact is a component for connection technology in industry, specifically designed for use in terminal blocks. With a pole count of 10 and a pitch of 4.2 mm, it enables the electrical connection of multiple connection points within a terminal module. The bridge is available in a silver-coloured finish and is used for secure and durable connections of conductors or cables in electrical circuits, particularly in applications requiring high contact stability and reliability.

Fixed Bridge

The term Fixed Bridge describes a component that cannot be removed or modified after installation without disassembling the entire terminal connection. Unlike removable bridges, which can be adjusted via a lever or screw, this bridge is inserted once and remains permanently in the terminal module. This ensures a stable and vibration-resistant connection, which is particularly advantageous in industrial environments subject to mechanical stress or vibrations.

Applications

The FBRN 10-4 N is typically used in industrial control and distribution systems where multiple conductors or cables must be electrically connected at a single point. It is suitable for applications in automation technology, machine building, electrical installations, and enclosures where a fixed, non-adjustable connection is required. The bridge is used in combination with Phoenix Contact terminal blocks featuring a pitch of 4.2 mm.

Functions and Features in Detail

The bridge features 10 connection poles, each establishing an electrical contact with an adjacent pole. This enables a parallel connection between all 10 points. The silver-coloured surface results from the metal material used, which is designed for electrical conductivity and corrosion resistance. The bridge does not include additional features such as indicators, protective switches, or integrated fuses, but serves exclusively for pure electrical connection.

Technology Explained Simply

The pitch of 4.2 mm defines the distance between individual connection points in the terminal block. This value is crucial for compatibility with other components in the same module. The Fixed Bridge fits precisely into terminals with this pitch, ensuring accurate and secure installation. The bridge is inserted into the terminal, where the contacts automatically connect to the respective connection points. The connection is established through mechanical pressure, creating a solid electrical path.

Compatibility and Accessories

The FBRN 10-4 N is specifically designed for terminal blocks with a 4.2 mm pitch. Suitable accessories that can be used in conjunction with this item include the cutting tool CUTFOX FB 1205985. This tool is used for precise and clean cutting of cables or conductors before insertion into the terminal, thereby supporting the installation process.

Installation and Mounting

Installation is performed by inserting the bridge into the corresponding terminal, aligning the bridge contacts with the terminal connection points. The bridge is securely seated in the terminal without requiring additional tools or screw connections. Once installed, the connection is not adjustable, making correct positioning during installation essential. The bridge is not suitable for use in terminals with a different pitch.

The bridge is not equipped with additional features such as indicators, protective switches, or integrated fuses, but serves exclusively for pure electrical connection.

Operational Advantages

The Fixed Bridge provides a reliable and durable electrical connection that cannot be loosened by mechanical stress or vibrations. The tool-free installation and high contact stability reduce the risk of errors in industrial systems. Use in combination with terminal blocks enables structured and clear wiring, simplifying maintenance and circuit diagnostics. The bridge is suitable for use in enclosures and industrial control systems where a stable and maintenance-free connection is required.
