Threaded busbar connector SIMBLOCK STB 50-2 - Al/Cu, 87320, grey 81002002

Busbar connectors and distribution blocks – reliable connections in electrical installations

SIMBLOCK STB 50-2 threaded busbar connector is an element used for safe and durable connection of aluminum and copper wires in electrical installations. Designed for both professional installers and end-users, it provides a reliable connection in distribution boards, control cabinets, and during the construction of machines and devices. The connector's design guarantees connection stability and minimizes the risk of wires loosening during operation.

The STB 50-2 connector is characterized by its versatility – it allows connection of wires with a cross-section from 6 mm² to 50 mm² (solid) and from 4 mm² to 35 mm² (stranded with ferrule). This makes it suitable for various applications where connecting wires with different parameters is required. The possibility of using both aluminum and copper wires eliminates the need for additional adapters or transition connectors. This solution will be particularly appreciated by installers who often deal with mixed installations.

Construction and mounting

The SIMBLOCK STB 50-2 connector has been designed for easy and quick installation. It has threaded clamps that provide a secure and stable connection of the wires. Made of high-quality materials, it guarantees durability and corrosion resistance. Mounting is done on a standard TS 35 rail or mounting plate, which facilitates integration with existing electrical infrastructure. Additionally, the thick walls of the housing prevent deformation during tightening of the wires, which translates into long-term connection reliability.

Application and benefits

• Versatility: Possibility of connecting aluminum and copper wires without the need for additional elements.
• Safety: UL486E certificate confirms a high standard of safety for Al/Cu connections.
• Durability: Made of high-quality materials ensures corrosion resistance and long-term reliability.
• Easy installation: Threaded clamps and the possibility of mounting on a TS 35 rail facilitate installation.
• Wide range of cross-sections: Supporting wires with a cross-section from 6 mm² to 50 mm² (solid) and from 4 mm² to 35 mm² (stranded with ferrule) provides application flexibility.
• Connection stability: The connector's design minimizes the risk of wires loosening during operation.
• Overheating protection: The unique shape of the core and the ribbing of the body promote heat dissipation, preventing overheating of the connection.

The SIMBLOCK STB 50-2 connector is an optimal solution for anyone who values quality, safety and convenient installation in electrical installations. It is a product worth recommending to both professionals and people who independently perform electrical work at home or in the garden.
