Al/Cu terminals – reliable connections of various types of wires

The Al/Cu terminal SL37.27 is an element used to connect aluminum and copper wires in electrical installations. Its versatility results from the ability to work with wire cross-sections from 6 mm² to 95 mm², making it useful in both home and industrial installations. The terminal design is based on a screw connection, providing a secure and durable connection.

This terminal is characterized by through-hole clamping channels for both the main and branch wires, which facilitates installation and ensures optimal current flow. Made of tinned aluminum alloy and galvanized steel, it guarantees corrosion resistance and long-term reliability. The tinning of aluminum is an important element – it prevents galvanic connections between aluminum and copper, which could lead to electrochemical corrosion.

Key features and applications:

• Material versatility: Designed to connect aluminum and copper wires – eliminates the need for additional adapters or connectors.
• Wide range of cross-sections: Supporting wires with a cross-section from 6 mm² to 95 mm² allows for use in various installations.
• Durable connection: Screw connection provides a solid and reliable electrical connection, resistant to vibrations and temperature changes.
• Corrosion resistance: Galvanizing of steel elements and tinning of aluminum protects against atmospheric factors and electrochemical corrosion.
• Compliance with standards: Meets the requirements of EN 61238-1 standard, which guarantees product safety and quality.
• Torque: The recommended tightening torque for the screws is 22 Nm – important for ensuring optimal electrical and mechanical contact.
• Installation: Installing the terminal requires the use of a wrench of the appropriate size (M8). Remember to tighten the screws correctly to avoid loosening the connection in the future.

This terminal is used wherever it is necessary to connect aluminum wires with copper wires – in electrical distribution boards, connection boxes, control cabinets and at the connection points of electrical devices. This is particularly important in situations where there are differences in the wire material, e.g. when connecting aluminum cables to devices with copper terminals or vice versa. Using the appropriate Al/Cu terminal ensures the safe and efficient operation of the electrical installation for a long time.
