High-current threaded connector 120 mm2 VSU 120 003901606

Robust connection for demanding installations

VSU 120 high-current connector is a reliable element for connecting wires in electrical installations where safety and high conductivity are crucial. Designed for wires with a cross-section of up to 120 mm², it is perfect for switchboards, connection boxes and other applications requiring a stable and durable connection. Its screw connection design ensures a secure contact and minimizes the risk of loosening connections during operation.

Construction and application

The VSU 120 connector is mounted on a standard DIN TH-35 mm rail, which simplifies and speeds up its installation. Made of high-quality thermoplastic material, it guarantees good electrical insulation and resistance to mechanical damage. The beige color makes it easier to identify inside the switchboard. This connector is primarily used in electrical installations with high loads, such as:

• Cable connections with large cross-sections
• Main and distribution switchboards
• Industrial installations
• Photovoltaic systems – connecting DC wires
• Applications requiring high connection reliability

Parameters and benefits

Rated current of 269 A and rated voltage of 1000 V confirm the possibility of using the connector in demanding working conditions. A wide range of permissible wire cross-sections (2.5 – 120 mm²) allows for flexible adaptation to specific installation needs. The screw connection ensures a secure and durable wire fixing, minimizing the risk of short circuits and open circuits. The use of thermoplastic material as an insulating material increases safety and protects against electric shock. Mounting on a DIN TH-35 mm rail is a standard solution that greatly simplifies the installation process and allows for quick construction or modification of the electrical system.
