The Phoenix Contact FBI 3-15 is a fixed bridge for terminal blocks, designed for use in industrial electrical installations. It connects three connection points in a row with a pitch of 15 mm, enabling a secure and durable electrical connection between multiple terminals. The bridge is insulated, ensuring electrical separation between individual poles and increasing operational safety. The bridge is silver-coloured, typical for metallic components in connection technology. The construction is designed for use in enclosures and control systems, where a stable and reliable connection is required.

Fixed bridge
The bridge is permanently mounted and cannot be removed or modified once inserted into the terminal. This ensures a permanent electrical connection between the connected conductors. The fixed design is particularly suitable for applications requiring a permanent connection, where no future modification or disassembly is planned.

Pitch 15 mm
The pitch of 15 mm corresponds to the standard for many industrial terminal blocks and allows compatible mounting in standard control panels and enclosures. This dimension is widely used in electrical and automation technology and ensures easy integration into existing systems. The bridge thus fits into terminal rows designed for this pitch.

Insulated design
The bridge is insulated, meaning the individual poles are electrically separated. This prevents unintended short circuits and increases operational safety. Insulation is an essential feature for safe use in electrical installations, especially in environments with increased risk of incorrect connections.

3 poles
The bridge connects three poles, making it suitable for applications where three conductors need to be electrically connected. This is relevant, for example, when connecting three phase conductors in a three-phase system or when connecting three conductors in parallel in control technology. The 3-pole design enables a compact and efficient connection without additional components.

Compatibility and accessories
The bridge is specifically designed for terminal blocks with a pitch of 15 mm. Compatible accessories, such as the CUTFOX FB 1205985 cutting tool, support installation and maintenance by enabling precise processing of conductors. The cutting tool is designed for use with terminals of this type and simplifies preparation of conductor ends.

Applications
The FBI 3-15 is used in industrial electrical engineering, particularly in enclosures, control systems, and automation plants. It is used to electrically connect multiple conductors without requiring additional connection components such as cable lugs or solder joints. The bridge is designed for use in permanently installed systems where a durable and reliable connection is required.

Installation and mounting
Mounting is done by inserting the bridge into the corresponding terminals of the terminal block. The fixed design requires no additional holding or screwing elements. The bridge is inserted directly into the terminals, with the insulation ensuring electrical separation of the poles. Installation is simple and does not require special tools, except for the cutting tool if conductors need to be prepared.

Operational advantages
The fixed bridge provides a reliable and durable electrical connection that remains stable under industrial conditions. The insulated design increases safety and prevents short circuits. The 3-pole construction enables a compact connection of multiple conductors, making installation in enclosures more efficient. Compatibility with the standard pitch of 15 mm ensures easy integration into existing systems.
