Threaded busbar connector SIMBLOCK STB 50 - Al/Cu, 87310, black 81001007

SIMBLOCK STB Threaded Busbar Connectors – Reliable Al/Cu Connections

SIMBLOCK STB 50 threaded busbar connector is an element designed for connecting aluminum and copper wires on TS 35 rails or mounting plates. The connector's design ensures a secure and durable connection, minimizing the risk of loosening connections during operation. This is a key solution for both professional installers and end-users who value the safety and reliability of electrical installations.

Construction and application

The STB 50 connector is characterized by a unique core construction and special ribbing of the body, which effectively dissipates heat generated during operation. This ensures that the connection remains stable even under high current loads. The use of high-quality materials guarantees corrosion resistance and long-term operation. The connector is compatible with both solid wires and stranded wires with ferrules, increasing its versatility. The ability to mount on a TS 35 rail facilitates quick and efficient installation in electrical switchboards.

• Application: Connecting aluminum and copper wires in electrical installations.
• Mounting: TS 35 rail or mounting plate – provides flexibility in choosing the installation method.
• Compatibility: Both with solid wires and stranded wires with ferrules – a wide range of applications.
• Rated voltage: Up to 1000 V AC/DC – possibility of use in various types of installations.
• Rated current: Up to 150 A (Cu and Al) – high efficiency and safety of use.

Key features and benefits

The SIMBLOCK STB 50 connector stands out from the competition with a number of advantages that translate into benefits for installers and users:

• Versatility: The ability to connect aluminum and copper wires eliminates the need to use additional adapters or transition connectors.
• Safety: UL486E certification confirms a high safety standard for Al/Cu connections, minimizing the risk of short circuits and fires.
• Durability: Thick housing walls prevent deformation during tightening of the wires, ensuring a stable connection for a long time.
• Easy installation: Allen screws with a fine thread allow precise tightening of the wires, and the cover color makes it easier to identify connected cables.
• Efficient heat dissipation: The special core design and body ribbing prevent overheating of the connection, increasing its reliability.
• Wide range of wire cross-sections: Support for cross-sections from 6 mm² to 50 mm² (solid) and from 4 mm² to 35 mm² (stranded wire with ferrule) provides flexibility in choosing the appropriate cables for a specific application.
