Threaded busbar connector STB 185-2 Al/Cu 87820 SIMBLOCK, black 81202007

Rail terminal blocks threaded – reliable Al/Cu connections

The STB 185-2 Al/Cu threaded rail terminal block is an element designed for connecting aluminum and copper conductors, providing a secure and durable connection in electrical installations. The terminal block's design is intended for easy installation and safe use for both professional installers and end-users.

Construction and application

The STB 185-2 is characterized by a solid construction and the ability to connect conductors with cross-sections from 6 mm² to 185 mm² (solid wire) and from 4 mm² to 150 mm² (stranded wire with ferrule). Additional space for a measuring connection allows for monitoring the connection status and installation monitoring. The use of special ribbing on the body ensures effective heat dissipation, which translates into stable operation even under high loads. The terminal block is compatible with TS 35 rails and mounting plates, making it easy to integrate into various types of switchboards and electrical cabinets.

Advantages and benefits

• Versatility: The ability to connect aluminum and copper conductors eliminates the need for additional adapters.
• Safety: Solid construction, thick housing walls, and precise thread ensure a stable connection resistant to vibrations and temperature changes.
• Easy installation: Hex key screws with a fine thread allow for quick and secure clamping of conductors.
• Installation monitoring: A dedicated space for a measuring connection facilitates control of the connection status and diagnostics of the electrical installation.
• Dust protection: Optional OSTB 185 dust cover provides additional protection against dirt and environmental influences.
• Ergonomics: The shape of the housing protects the installer's hands during work.
• Durability: The use of high-quality materials guarantees a long service life of the terminal block even in difficult operating conditions.

The STB 185-2 terminal block is an optimal solution for installers looking for a reliable and easy-to-install element for connecting Al/Cu conductors, as well as for end-users who value safety and durability of electrical installations.
