SIMBLOCK STB 300 threaded busbar connector - Al/Cu, 87910, blue 81301003

SIMBLOCK STB 300 Threaded Busbar Connector – Reliable Al/Cu Wire Connection

The SIMBLOCK STB 300 threaded busbar connector is designed for connecting aluminum and copper wires on TS 35 rails or mounting plates. Its construction ensures a secure and durable connection, and its additional feature is the ability to connect a measuring connector, which facilitates monitoring the connection status and the installation. This makes it an ideal solution for both professional installers and end-users who value safety and reliability.

Construction and Application

The STB 300 connector has been designed with ease of installation and use in mind. Made of high-quality materials, it guarantees connection stability even under heavy loads. Its design allows for the connection of two wires with a cross-section of 150 to 300 mm² (solid) or 120 to 240 mm² (stranded with ferrule). Additionally, the connector has a place for a measuring connector with a cross-section of 1.5 to 10 mm² (solid) or 1.5 to 6 mm² (stranded with ferrule). This solution is particularly useful in installations requiring precise monitoring of electrical parameters.

The connector finds wide application in residential and industrial construction, in electrical switchboards, in machine building, and in renewable energy systems. It is compatible with the dedicated dust cover OSTB 300, which provides additional protection against dirt and mechanical damage and allows for convenient marking of the connection.

Advantages and Benefits

• Versatility: The ability to connect aluminum and copper wires eliminates the need to use different types of connectors.
• Safety: A secure and stable connection ensures minimal resistance and reduces the risk of overheating.
• Monitoring: The additional space for a measuring connector allows easy access to the measurement point without the need to disconnect the circuit.
• Easy Installation: The connector's design facilitates quick and trouble-free mounting on a TS 35 rail or mounting plate.
• Durability: Made of high-quality materials, it guarantees long-term use even in harsh conditions.
