Threaded busbar connector STB 300-2 Al/Cu 87920 SIMBLOCK, black 81302007

Busbar connector Al/Cu – a reliable connection for your installation

The threaded busbar connector STB 300-2 SIMBLOCK is a solid and versatile solution for connecting aluminum and copper conductors in electrical installations. Designed for both industrial applications and residential construction, it provides a safe and durable connection. Its construction allows mounting on TS 35 rails and mounting plates, providing great flexibility during installation.

Design and application

The STB 300-2 connector has been designed with ease of installation and safety in mind. Made of high-quality materials, it guarantees reliability even in harsh conditions. Suitable for conductors with a cross-section from 120 mm² to 300 mm² (cable with ferrule) and from 150 mm² to 300 mm² (wire), it allows connection of a wide range of conductors. An additional space for a measuring connection is a practical solution for installers who need to monitor the installation parameters without having to disconnect it. A dedicated OSTB 300 dust cover additionally protects the measuring connection from dirt and damage.

Advantages and benefits

• Versatility: The ability to connect aluminum and copper conductors eliminates the need to use different types of connectors.
• Safety: Construction compliant with DIN EN 50274 prevents accidental contact with live parts, protecting the installer during work.
• Durability: Made of high-quality materials guarantees long-lasting and reliable operation.
• Easy installation: Mounting on TS 35 rails or mounting plates is quick and easy.
• Additional features: Integrated measuring connection facilitates monitoring of installation parameters without the need to disconnect it.
• Spaciousness: Larger space inside the connector compared to competitive solutions makes it easier to install cables with large cross-sections and use ferrules.
• Short-circuit protection: Protection against current breakthrough increases safety of use.
• High torque: The shape of the screw provides high torque during tightening, and the specially finished end protects aluminum conductors from damage.

The STB 300-2 connector is the optimal choice for professionals looking for a reliable and functional solution for building safe and efficient electrical installations.
