DIN rail screw connector SIMBLOCK STB 50-2 - Al/Cu, 87320, blue 81002003

SIMBLOCK Busbar Connectors – Reliable Al/Cu Connections

The SIMBLOCK STB 50-2 busbar connector is an element used for safe and efficient connection of aluminum and copper wires in electrical installations. Designed for both professionals and end-users, it provides a durable connection and easy mounting on TS 35 rail or a mounting plate. This is an ideal solution for both construction, industrial automation and renewable energy installations.

Design and application

The STB 50-2 connector stands out with its unique design that minimizes connection heating. The special shape of the core and the ribbing of the body effectively dissipate heat, ensuring stable operation even under high loads. The ability to connect wires with a cross-section from 6 mm² to 50 mm² (solid) and from 4 mm² to 35 mm² (stranded with ferrule) makes it a versatile element in many applications. Additionally, the solid construction of the connector guarantees resistance to mechanical damage and ensures long-term reliability.

Advantages and benefits

• Versatility: Designed for connecting aluminum and copper wires – eliminates the need for additional adapters.
• Safety: High quality workmanship and UL 486E certificate guarantee safe operation.
• Durability: Thick housing walls ensure stability on the TS 35 rail and resistance to deformation during wire tightening.
• Easy installation: Hex key screws with a fine thread allow precise tightening of the wires, and the color of the body cover facilitates identification of the connected cables (blue).
• Efficient heat dissipation: The unique design minimizes the risk of overheating the connection, which translates into a longer service life of the installation.
• Rated current: Provides a safe connection with a rated current of up to 150A for copper and aluminum wires.
• Rated voltage: Adapted to work at a voltage of up to 1000 V AC/DC.

Using SIMBLOCK connectors guarantees a professionally executed electrical installation that meets the highest standards of safety and reliability. This solution is appreciated by installers for its ease of installation and by end-users for trouble-free operation for many years.
