The Klauke cable lug type 4R6 is a tube cable lug designed for use in enclosure construction, specifically intended for multi-strand round conductors, for example according to VDE 0295 class 2, as well as for round-compressed multi-strand sector conductors. It connects electrical conductors securely and reliably, with the connection being achieved through mechanical crimping within the cable lug. The construction ensures a stable and durable electrical connection that remains intact even under dynamic loads during operation.

Applications

The cable lug 4R6 is primarily intended for use in enclosures and electrical distributions, where a secure and durable connection between cables and screw terminals or other connection elements is required. It is particularly suitable for applications involving multi-strand conductors with a cross-sectional area of 25 mm², for example in industrial electrotechnics, building automation, or in machine and plant engineering. The use of multi-strand conductors requires special crimping to ensure optimal contact surface and mechanical strength.

Functions and Equipment in Detail

The cable lug 4R6 features a flat seating surface and precise end finishing, enabling easy and secure insertion of the cable. Crimping is achieved through mechanical deformation of the cable lug, creating a firm and durable connection between the conductor and the lug. The article identification marking on the cable lug facilitates identification and sorting during storage and assembly processes. The use of annealed copper material (Cu according to EN 13600) ensures optimal material and crimping properties, guaranteeing uniform and reliable crimping.

Technology Explained Simply

The cable lug is made of copper that is galvanically tinned to form a corrosion-protective layer. This tinning protects the copper from oxidation and thus prevents deterioration of electrical conductivity over time. Crimping is achieved through mechanical deformation of the cable lug, securing the conductor firmly within the lug.

Compatibility and Accessories

The cable lug 4R6 is designed for multi-strand round conductors with a cross-section of 25 mm². It is compatible with screw terminals having a screw diameter of M6. The use of multi-strand conductors requires special crimping to ensure optimal contact surface.

Installation and Mounting

Mounting of the cable lug is performed by inserting the cable into the lug and then crimping it using an appropriate tool. The crimping must be carried out such that the conductor is fully anchored within the lug and a secure connection is formed. Installation typically takes place within an enclosure, where the cable lug is connected to a screw terminal.

Operational Advantages

The cable lug 4R6 provides a reliable and durable connection that remains intact even under dynamic loads during operation. The use of annealed copper material ensures optimal material and crimping properties, guaranteeing uniform and reliable crimping. The galvanic tinning protects the copper from corrosion and thus prevents deterioration of electrical conductivity over time. The article identification marking on the cable lug facilitates identification and sorting during storage and assembly processes.
