General
Shielding clamp
Shield contactable diameter

The WAGO 790-108 is a shield clamp designed specifically for secure and reliable connection of shielded cables in industrial applications. It serves as a mechanical and electrical connection point for shielded cables, where the shield is connected directly via the contactable diameter. The clamp is 11 mm wide and allows for stable mounting on standard busbars or carriers, making it suitable for use in enclosures and control systems. The integrated knurled screw ensures secure fastening and a lasting electrical connection.

Applications

The shield clamp 790-108 is used in industrial electrical engineering, particularly in systems handling disturbed or sensitive signals, such as automation systems, controls, or measuring devices. It provides shielding against electromagnetic interference and ensures that signals are transmitted safely and without interference via shielded cables. It is typically used in enclosures where multiple cables are connected to a busbar.

Functions and Features in Detail

The clamp features a contactable shield diameter, enabling direct and electrically conductive connection of a cable’s shield. The 11 mm width ensures a good fit on standard busbars and carriers. The integrated knurled screw simplifies installation and ensures a secure connection. The design allows for a safe and durable electrical connection without requiring additional tools or adapters.

Technology Explained Simply

The shield clamp acts as an interface between the cable shield and a busbar or other conductor. The shield, often made of a metallic braid, is inserted into the clamp and tightened using the knurled screw, establishing an electrical connection that maintains the cable’s shielding. The 11 mm width is compatible with standard busbars commonly used in industrial electrical engineering. Material selection and construction ensure high mechanical stability and electrical conductivity.

Compatibility and Accessories

The shield clamp 790-108 is compatible with various carriers and busbars, including models 790-100, 790-110, 790-112, 790-113, 790-114, 790-115, 790-133, 790-134, 790-145, 790-190, 790-191, 790-192, and 790-193. These components allow flexible mounting in various enclosure configurations. Standard use is with copper (Cu) busbars of dimensions 10 mm x 3 mm. Combination with carriers featuring grounding feet or specially perforated support rails expands application possibilities in complex installations.

Installation and Mounting

Mounting is done by securing the clamp to a busbar or carrier using the integrated knurled screw. The cable shield is inserted into the clamp and tightened with the screw, establishing an electrical connection. Installation requires no additional tools beyond a screwdriver or suitable knurled screwdriver. Positioning depends on enclosure planning and the number of cables to be connected.

Operational Advantages

The shield clamp 790-108 provides a reliable and durable connection for shielded cables. The integrated knurled screw enables easy and secure installation, reducing installation time. Use in combination with standard busbars and carriers allows flexible and modular system design. High electrical conductivity and mechanical stability ensure long service life and minimize the risk of contact loss or interference during operation.
