Al/Cu bimetallic terminal 10-50 mm / 1.5-10 mm SLIW50

Two-sided Al/Cu terminals – reliable connections in electrical installations

The SLIW50 two-sided terminal is an element used to connect aluminum and copper wires with cross-sections of 10-50 mm² and 1.5-10 mm², respectively. Its construction based on screw terminals piercing the insulation (IPC) ensures quick and secure installation, minimizing working time and the risk of errors. The galvanized surface of the terminal guarantees corrosion resistance and long-term reliability, even in harsh environmental conditions.

This model is particularly useful in situations where it is necessary to connect wires made of different materials – aluminum and copper. It provides optimal electrical conductivity and minimizes the risk of galvanic corrosion, which can occur with direct contact between these metals. This ensures that the installation remains safe and efficient for a long time.

Construction and application

The SLIW50 terminal is characterized by a through terminal channel for the main wire and a one-sided open channel for the branch wire. This design facilitates the connection of wires of different thicknesses and ensures a solid mechanical connection. The terminal is insulated, which increases safety and minimizes the risk of short circuits.

• Versatility: Possibility of connecting Al/Cu wires of different cross-sections.
• Quick installation: IPC (insulation piercing) technology shortens installation time.
• Durability: Galvanized surface protects against corrosion.
• Safety: Insulated construction minimizes the risk of short circuits.
• Compatibility: Designed to work with a wide range of aluminum and copper wires.

SLIW50 two-sided terminals are widely used in electrical installations of residential, commercial and industrial buildings. They are ideal for connecting distribution boards, control cabinets and other electrical devices requiring a reliable connection of wires with different parameters. Installation is simple for both experienced installers and people with basic knowledge of electrical engineering.
