Al/Cu terminal, 10-50 Al/2.5-10 Cu SM1.11

Product features

• Reliable connection of different material wires

The SM1.11 connector is used to connect aluminum and copper wires, providing a durable and safe electrical connection. Designed for use in electrical installations where connection of materials with different characteristics is required. The connector design allows for a connection that is not stressed mechanically, which translates to its long-term reliability.

Construction and application

The SM1.11 is characterized by through-hole clamping channels for both the main and branch wires. Installation is done with an M8 screw, ensuring a solid and secure connection. The galvanized surface of the connector protects against corrosion, and the cleaned contact surface with contact paste minimizes transition resistance and ensures optimal conductivity.

This type of connector is primarily used for:

• Connecting aluminum wires to devices with copper terminals (and vice versa).
• Making branches in electrical installations.
• Connecting wires in electrical distribution boards.
• Building cable connections.

Key features and benefits

• Material compatibility: Allows connecting aluminum wires (10-50 mm²) with copper wires (2.5-10 mm²), eliminating problems related to electrochemical corrosion.
• Durability and reliability: The connector design and materials used guarantee a long-lasting and stable connection, resistant to vibration and temperature changes (operating range: -40°C to +80°C).
• Easy installation: The screw mounting system provides simple and quick installation, without the need for specialized tools other than an M8 wrench.
• Safety: Galvanizing the surface protects against corrosion, and the contact paste minimizes transition resistance, which translates to the safety of using the electrical installation.
• Compliance with standards: The product meets the IEC 61238-1 standard, confirming its high quality and safety of use.
• Universality: Both the main and branch wires can be connected through the through channel - it does not matter from which side we connect a given wire.

The SM1.11 connector is a practical solution for both professional installers and end-users looking for a reliable way to connect aluminum and copper wires in their electrical installations.
