Al/Cu terminal, 16-95 Al/2.5-25 Cu SM2.11

Al/Cu Terminal – Reliable Connection of Wires

The SM2.11 terminal is an element used to connect aluminum and copper wires of different cross-sections. It is a key component in electrical installations where a safe and durable connection of materials with different properties is required. This terminal ensures optimal current conduction and minimizes the risk of galvanic corrosion, which can occur with direct contact between aluminum and copper.

Construction and Application

The SM2.11 terminal is characterized by a screw construction, which ensures a firm and strong connection of the wires. It is designed to connect aluminum wires with a cross-section from 16 to 95 mm² with copper wires with a cross-section from 2.5 to 25 mm². The terminal channels for both wires are through, which facilitates installation and provides adequate contact surface. Zinc coating of the terminal surface increases its corrosion resistance and ensures long-term reliability.

This type of terminal is widely used in:

• Electrical installations in residential and industrial buildings: For connecting power supply wires to electrical devices.
• Energy distribution boards: For creating connections between different electrical circuits.
• Cable connections: For connecting aluminum cables to devices equipped with copper terminals.
• Modernization of existing installations: In situations where it is necessary to replace a fragment of the installation or connect a new device.

Advantages and Benefits

• Material compatibility: The special design of the terminal minimizes the risk of galvanic corrosion between aluminum and copper, ensuring a long-lasting and stable connection.
• Safety: A firm screw connection guarantees low transition resistance and minimizes the risk of overheating and short circuit.
• Versatility: A wide range of permissible wire cross-sections (Al 16-95 mm², Cu 2.5-25 mm²) allows the terminal to be used in various types of installations.
• Easy installation: Through terminal channels facilitate wire routing and provide quick and convenient installation.
• Durability: The zinc-coated surface protects against corrosion, which extends the life of the terminal even in harsh environmental conditions.
• Compliance with standards: The product meets the required safety standards, which guarantees its reliability and safety of use (no information about specific standards in the provided data).

Thanks to these features, the SM2.11 terminal is an optimal solution for both professional installers and end-users looking for a reliable element for their electrical installations. Installation is simple, and the certainty of operation – high.
