Al/Cu terminal, 16-120 Al/6-35 Cu SM2.21

Al/Cu Terminal – Reliable connection of different material wires

The SM2.21 terminal is a solid solution for connecting aluminum and copper wires with cross-sections of 16-120 mm² (Al) and 6-35 mm² (Cu) respectively. The terminal's screw connection design ensures a secure and durable connection, minimizing the risk of loosening during operation. Zinc coating of the surface provides corrosion resistance, which is particularly important in installations exposed to moisture and varying weather conditions.

Construction and application

The SM2.21 terminal is designed for creating branch or straight connections in electrical installations. Its construction, with through terminal channels for both aluminum and copper wires, facilitates installation and ensures optimal clamping. This allows for obtaining low connection resistance, which translates to energy efficiency and safety of use. This terminal is used in switchboards, connection boxes and in direct wire connections in electrical installations of residential, commercial and industrial buildings.
