Threaded busbar connector STB 50-3 Al/Cu 87360 SIMBLOCK, green 81003005

Rail-mounted threaded connectors for Al/Cu connections

The STB 50-3 Al/Cu threaded rail connector is a reliable solution for connecting aluminum and copper wires, designed for demanding electrical installations. This product from SIMBLOCK, a renowned manufacturer of electrical equipment, combines durability, safety and ease of installation. Using this connector guarantees a secure and long-lasting connection, minimizing the risk of failure and energy loss.

Design and application

The STB 50-3 connector is designed for mounting on TS 35 rail or a mounting plate. Its design allows connection of up to six wires with a cross-section from 6 mm² to 50 mm² (solid) or from 4 mm² to 35 mm² (stranded with ferrule). This makes it ideal for use in electrical switchboards, machine building, industrial automation and renewable energy installations. The ability to connect aluminum and copper wires without the risk of galvanic corrosion is a key advantage of this solution. The unique shape of the core and the ribbing of the body effectively dissipate heat, ensuring stable operation even under high loads.

Advantages and benefits

• Versatility: The ability to connect aluminum and copper wires in one connector eliminates the need for additional adapters and reduces installation costs.
• Safety: High-quality materials and precise workmanship guarantee a reliable connection, resistant to vibration and temperature changes. This protects against short circuits and overloads.
• Durability: Thick-walled housing provides stability on the TS 35 rail and resistance to mechanical damage during wire tightening.
• Easy installation: Allen screws with a fine thread allow for quick and secure wire clamping. The cover color facilitates identification of connected cables.
• Thermal resistance: The special design of the connector ensures efficient heat dissipation, which translates to a longer connection life and minimizes the risk of overheating.
• Certificates: The product has UL 486E, FI, VDE certificates and CE, RoHS, REACH declarations of conformity - confirming its high quality and safety of use.

The STB 50-3 connector is an investment in a safe and reliable electrical installation that will meet the expectations of both professional installers and end users.
