Threaded busbar connector STB 185 Al/Cu 87810 SIMBLOCK, brown 81201015

Solid connections for electrical installations

The STB 185 Al/Cu SIMBLOCK threaded busbar connector is a reliable solution for connecting aluminum and copper wires in switchboards and other electrical circuits. The connector's design allows for safe and durable connections of large cross-section wires, both stranded and with ferrules. This makes it ideal for both professional installers and end-users who value safety and installation durability.

Functionality and mounting flexibility

The STB 185 connector is designed with ease of installation in mind. The ability to install on TS 35 rail or a mounting plate provides great freedom in choosing the installation method, adapting to the specifics of a particular installation. Additionally, the connector has dedicated inputs for wires with cross-sections of 95-185 mm² (solid) and 70-150 mm² (stranded with ferrule), ensuring compatibility with a wide range of wires.

Additional conveniences for measurements and maintenance

The connector is distinguished by the presence of additional space for a measuring connection, which facilitates the connection of measuring leads without the need for additional adapters. A dedicated dust cover OSTB 185 (available separately) provides free access to the measuring connection during maintenance or measurements, while protecting it from dirt. This well-thought-out solution increases work comfort and minimizes the risk of errors during service operations.
