The Fixed Bridge FBI 10- 8 from Phoenix Contact is a component for connection technology in industrial electrical engineering. With a pole count of 10 and a pitch of 8 mm, it is designed for use in terminal block constructions where a fixed electrical connection between multiple contacts is required. The bridge is insulated and has a silver-coloured appearance, typical for metallic components in electrical installations. It is used for secure and durable connection of conductors in switchgear, control systems, or distributors, ensuring mechanical stability and electrical reliability of the circuit.

Fixed Bridge

The term fixed bridge describes a non-removable connecting element placed between two or more terminal poles to electrically connect them. Unlike removable bridges, which can be detached via a locking mechanism, this bridge cannot be removed after installation without tools or causing damage. This makes it particularly suitable for applications requiring a permanent connection, such as in fixed installations or for connecting conductors that are not frequently changed.

Pitch 8 mm

The pitch of 8 mm defines the spacing between individual poles of the terminal block into which the bridge is inserted. This dimension is a standard in industrial electrical engineering and ensures compatibility with other components designed for an 8 mm pitch. The bridge thus fits into standard terminal blocks installed in enclosures, distribution boxes, or control systems. Adhering to the pitch is essential for proper installation and to avoid misplacement.

Applications

The Fixed Bridge is used in industrial plants where an electrical connection between multiple terminal poles is necessary. Typical applications include connecting N conductors in distributors, parallel connection of conductors to a common potential, or connecting protective earth conductors (PE) in switchgear. The bridge is used in enclosures, control systems, drive technology, and other electrical installations where a fixed, non-removable connection is required.

Insulated Design

The bridge is designed with insulation, meaning the metallic connecting elements are surrounded by insulating material that ensures electrical isolation between individual poles. This prevents unintended short circuits or current flow between adjacent terminals that should not be electrically connected. Insulation is especially important in complex circuits where the risk of incorrect connections or short circuits exists.

Compatibility and Accessories

The bridge is specifically designed for terminal blocks with an 8 mm pitch. As compatible accessory, the cutting tool CUTFOX FB 1205985 is offered, which can be used for precise processing of conductors or cables to be inserted into the terminals. The tool supports the installation and preparation of conductors to ensure a clean and secure connection.

Installation and Mounting

Mounting is done by inserting the bridge into the corresponding terminal poles of the terminal block. The bridge is positioned so that it electrically connects the desired poles. The fixed connection requires no additional screws or holding elements—the bridge is securely held in place by the pitch and the shape of the terminals. Installation typically occurs during the assembly of the entire switchgear or during retrofitting of existing systems.

Operational Advantages

The fixed connection ensures high mechanical stability and electrical reliability. With no moving parts or locking mechanisms, the bridge is maintenance-free and resistant to vibrations and mechanical stress. The insulated design increases operational safety by preventing short circuits between adjacent poles. The bridge is designed for use in industrial environments where high demands on reliability and safety apply.
