SIMBLOCK STB 185-2 Threaded Busbar Connectors – a reliable Al/Cu connector

The SIMBLOCK STB 185-2 threaded busbar connector is an element designed for safe and efficient connection of aluminum and copper wires on TS 35 rails. The connector's design, combined with high-quality materials, ensures a stable connection and minimizes the risk of overheating. This is an ideal solution for both professional installers and end-users who value durability and safety of electrical installations.

Design and application

The STB 185-2 connector has been designed for easy assembly and disassembly. It allows connection of up to four wires with a cross-section from 95 to 185 mm² (solid) or from 70 to 150 mm² (stranded with ferrule). Additionally, it has a dedicated space for a measuring connection (2x 1.5-10 mm² for solid wire and 2x 1.5-6 mm² for stranded wire with ferrule), which facilitates monitoring of installation parameters. The connector is compatible with TS 35 rails and mounting plates. Therefore, it finds application in electrical switchboards, control cabinets and other installations requiring a reliable connection of wires.

Advantages and benefits

• Versatility: The ability to connect aluminum and copper wires in one element eliminates the need for additional adapters.
• Safety: UL486E certification confirms a high safety standard for Al/Cu connections. Thick housing walls ensure stability and resistance to mechanical damage.
• Easy installation: Hex key screws with a fine thread guarantee a secure clamping of the wires. The cover color coding facilitates identification of connected wires.
• Installation monitoring: A dedicated space for a measuring connection allows monitoring of the connection status and operating parameters of the installation.
• Durability: Made of high-quality materials, resistant to corrosion and weather conditions.
• Additional protection: The OSTB 185 dust cover can be used to provide additional protection against dirt and mechanical damage to the measuring connection.
• Practicality: The compact size allows for optimal use of space in the switchboard.

Using SIMBLOCK connectors guarantees a professionally executed electrical installation that meets the highest standards of safety and reliability.
