The product is a flat zigzag band from Phoenix Contact, type ZBF 5,LGS:FORTL.ZAHLEN 121-130, with manufacturer number 0808671:0121. It is used for labelling terminals in electrical installations and enables clear, visual identification of connections. The band is 10-piece and is printed lengthwise with consecutive numbers from 121 to 130, with the numbers printed in white. Labelling is achieved by interlocking onto terminals with a width of 5 mm, ensuring secure and durable fixation. The flat shape of the band fits optimally onto narrow terminals and allows for compact mounting in enclosures or control systems.

Applications
This zigzag band is specifically designed for use in industrial and commercial electrical installations where precise and unambiguous labelling of terminals is required. It is commonly used in control systems, distributors, enclosures, or during machine wiring to avoid confusion and facilitate maintenance and servicing. The consecutive numbering from 121 to 130 enables systematic and logical assignment of terminals, particularly in larger installations with many connections.

Functions and Features in Detail
The band is made of a flexible, flat material that easily adapts to terminals. The lengthwise printed labelling ensures that the numbers are visible along the entire length of the band, improving readability even when viewed at an angle. The white colour provides high contrast against dark or metallic terminals, making the numbers clearly visible. Installation is done by interlocking, where the band is inserted into the terminal and fixed by a locking mechanism. This prevents accidental dislodging and ensures stable fixation.

Technology Explained Simply
The terminal width of 5 mm is a standard size in electrical installations, making the zigzag band universally applicable. The flat design minimises space requirements and allows for dense terminal arrangement. The consecutive numbering from 121 to 130 is especially useful when a specific sequence or assignment of terminals is required, for example during circuit diagram documentation or servicing complex systems. The interlocking is achieved via a mechanical locking mechanism that securely holds the band without requiring additional fastening materials such as adhesive or screws.

Compatibility and Accessories
The zigzag band is specifically designed for terminals with a width of 5 mm and thus fits a wide range of standard terminals used in electrical work. No special accessories are required, as installation is done solely by interlocking. Compatibility is ensured due to standard dimensions and universal mounting method.

Installation and Mounting
Mounting is done by simply inserting the zigzag band into the terminal. The locking function prevents the band from slipping out. Installation is quick and requires no tools. The flat shape allows for easy handling, even in tight enclosure spaces. The labelling is immediately visible after installation, simplifying documentation and maintenance of the system.

Operational Advantages
The clear, consecutive labelling reduces errors during installation and maintenance. The white colour ensures good readability, even under low lighting conditions. The interlocking provides durable fixation without requiring additional materials. The flat design enables compact mounting, which is particularly advantageous in confined enclosures. The 10-piece configuration provides sufficient quantity for small to medium-sized projects.
