The OBO Bettermann cable holder type 2031 M 15 FS is a metallic fastening element for the secure guidance and mounting of cable bundles in electrical installations. It is specifically designed for applications requiring high mechanical load capacity and fire resistance, particularly in areas above fire protection ceilings. The construction allows for mounting on walls and ceilings, with the closure being openable without tools, simplifying installation and maintenance. The holder is approved as a cable-specific variant for electrical function retention according to DIN 4102 part 12, making it suitable for installations in fire protection areas. Detailed information on approved installation variants is contained in the corresponding test documents.

Applications

The cable holder is used in electrical installations where permanent and secure fastening of cable bundles is required, particularly in buildings with increased fire protection requirements. It is suitable for mounting above fire protection ceilings, where cables must continue to function in the event of fire. The use is common in industrial, commercial, and public buildings, where compliance with standards such as DIN 4102 part 12 for electrical function retention is mandatory. Mounting on walls and ceilings allows for flexible arrangement within the installation area.

Functions and Equipment in Detail

The holder is made of metal and offers high mechanical stability, making it suitable for demanding installations. The design ensures that it maintains its function even in the event of fire, qualifying it for use in fire protection systems. The cable-specific version is approved for use with cables of type NYM3x1,5 St FS, with exact installation variants described in the test documents. The closure mechanism allows opening without tools, accelerating installation and maintenance and eliminating the need for special tools.

Technology Explained Simply

The cable holder is a fastening element that securely holds cable bundles and protects against displacement. The metallic construction ensures high strength, which remains intact even under mechanical stress. Approval according to DIN 4102 part 12 means the holder maintains its function in the event of fire, which is crucial for the safety of electrical installations in buildings with fire protection requirements. The ability to open without tools simplifies installation and maintenance, as no additional tools are required. Mounting on walls and ceilings offers flexibility in planning cable routing.

Compatibility and Accessories

The cable holder is compatible with cables of type NYM3x1,5 St FS, as specified in the approval according to DIN 4102 part 12. Suitable accessories include compatible cable holders such as the SHS15 cable holder (H56 mm, W34 mm, galvanized DIN EN 10346) and the BFM-MSH 15 metal cable holder with function retention (article number 2110-40-0042). These components can be used in similar application areas, particularly in fire protection installations, where mechanical strength and function retention during fire are required.

Mounting and Installation

Installation is carried out on walls and ceilings, with the holder’s construction enabling secure fastening. The closure can be opened without tools, speeding up installation and simplifying maintenance. Exact mounting instructions and installation variants are documented in the test documents, which should be referenced for the respective application. Use must comply with applicable standards and regulations, particularly DIN 4102 part 12.

Advantages in Operation

The use of the cable holder provides high mechanical stability and safety, especially in fire protection systems. Approval for electrical function retention according to DIN 4102 part 12 ensures that cables continue to function in the event of fire. The tool-free opening of the closure reduces installation effort and speeds up the process. Mounting on walls and ceilings offers flexibility in planning cable routing, facilitating integration into existing installations. Use in combination with compatible accessories such as SHS15 or BFM-MSH 15 expands application possibilities in complex installation scenarios.
