Threaded busbar connector STB 95-2 Al/Cu 87520 SIMBLOCK, grey 81102002

Threaded busbar connector for Al/Cu connections

This STB 95-2 threaded busbar connector from SIMBLOCK is a reliable solution for connecting aluminum and copper wires in electrical installations. Designed for durability and safety, it performs well in construction, industry, and renewable energy systems. Its construction allows for secure and stable connections, minimizing the risk of failure and ensuring long-term operation.

Construction and application

The STB 95-2 connector is designed for mounting on TS 35 rail or a mounting plate. It allows the connection of two solid wires with a cross-section from 16 to 95 mm² and two stranded wires with a ferrule with a cross-section from 10 to 70 mm². Additionally, it has a dedicated place for a measuring connection, which facilitates monitoring the connection status and monitoring the installation. This makes it possible to precisely diagnose problems and quickly respond to any irregularities.

This connector is particularly useful in situations where it is necessary to connect wires made of different materials – aluminum and copper. The special design of the core and the ribbing of the housing ensure effective heat dissipation, which translates into connection stability even under high loads. Thick housing walls guarantee stability on the TS 35 rail and resistance to deformation during wire tightening.

Key features and benefits

• Versatility: Ability to connect aluminum and copper wires of different cross-sections.
• Safety: Additional space for a measuring connection facilitates monitoring the connection status.
• Durability: Made of high-quality materials, resistant to mechanical damage and corrosion.
• Easy installation: Hex key screws with a fine thread ensure secure wire compression.
• Dust protection: Dedicated dust cap OSTB 95 provides access to the measuring connection without the risk of contamination.
• High resistance to loads: Rated voltage up to 1000 V AC/DC and rated current up to 232 A (Cu) / 200 A (Al) guarantee safe operation in demanding conditions.
• Ergonomics: The shape of the housing protects the installer's hands during work.

Thanks to these features, the SIMBLOCK STB 95-2 connector is an ideal choice for both professional installers and end-users looking for a reliable solution for their electrical installations.
