The SM4.21 parallel connector is suitable for strain-relieved aluminum-copper connections and enables a reliable connection between aluminum main conductors and copper branch conductors.
Thanks to the split upper section, two copper branch conductors of different diameters can be connected simultaneously to an aluminum main conductor. The connector is factory-brushed and pre-treated with contact grease, ensuring easy and secure installation. Before installation, the conductors simply need to be brushed and greased accordingly.
Key Features:
- For aluminum-copper (Al/Cu) connections
- For strain-relieved connections
- Connection of two copper branch conductors possible
- Branch conductors of different diameters are possible
- Split upper connector section
- Factory-brushed and pre-treated with contact grease
- Version with 2 × M10 screws
- Simple and easy to install
The SM4.21 parallel connector is a practical solution for branch connections in electrical distribution networks and is particularly suitable for applications in grid construction and power distribution.
