The cable clamp 2033 SP from OBO Bettermann is a standard version for general installations in the electrical and IT sectors, particularly for applications in intermediate ceilings and intermediate wall constructions. It is used for the secure fixation of cables and lines to base structures and enables orderly routing within indoor environments. The clamp is made of polyamide (PA) and is available in light grey (RAL 7035), allowing it to blend visually into typical installation environments.

Applications

The cable clamp 2033 SP is designed for use indoors, where a firm and permanent fixation of cables is required. Typical application scenarios include routing of NYM cables (e.g. NYM3x1,5) in intermediate ceiling constructions, on wall claddings, or in other structural intermediate spaces, where low installation depth and secure holding are essential. The clamp is particularly suitable for installations where cables are not subjected to strong mechanical stress.

Functions and Equipment in Detail

The cable clamp features a clamping height of 9 mm, sufficient to securely fix cables with a diameter up to approximately 9 mm. When used with a spacer, the effective clamping height increases to 13 mm, providing greater flexibility for securing thicker cables or meeting minimum spacing requirements. The clamp is designed for simple and quick installation, with the exact mounting technique depending on the base material (e.g. plasterboard, concrete, wood).

Technology Explained Simply

The cable clamp is made of polyamide (PA), a thermoplastic material known for its high strength, heat resistance, and chemical resistance. This material choice ensures long service life and reliable performance under normal indoor conditions. The design of the clamp allows for secure clamping of the cable through elastic deformation when inserted, preventing shifting or loosening. The clamping height of 9 mm (13 mm with spacer) is matched to common cable diameters in electrical installations, particularly for NYM cables with a 3x1.5 mm² cross-section.

Compatibility and Accessories

The cable clamp 2033 SP is designed for use with NYM3x1,5 type cables, with actual compatibility depending on the cable thickness. The clamp can be combined with a spacer to increase the clamping height, enabling the securing of larger cables or meeting specific spacing requirements.

Installation and Mounting

Installation is carried out by placing the cable clamp in the designated position and securing it to the base structure using screws or anchors inserted into the 6 mm Ø hole. Cables are inserted into the clamping opening, where the clamp’s shape ensures secure holding. When using a spacer, it is placed between the clamp and the base structure to achieve the increased clamping height. Installation does not require special tools, although the selection of appropriate fastening materials (e.g. screw length, anchor type) depends on the base material.

The cable clamp 2033 SP offers a reliable and simple cable fixation solution for indoor installations. The combination of polyamide construction, standard clamping height, and the option to increase clamping height with spacers makes it a flexible solution for various application scenarios. The clamp is designed for use in intermediate ceilings and intermediate walls, where clean and orderly cable routing is required. The light grey colour (RAL 7035) ensures discreet integration into typical indoor installations.

Operational Advantages

The cable clamp 2033 SP enables quick and secure cable fixation without additional tools. The polyamide material ensures high mechanical stability and long service life. Compatibility with spacers extends application possibilities, especially for larger cable diameters or when spacing regulations must be observed. The standard version is optimised for general applications and is particularly suitable for electrical and IT installations indoors.
