Threaded busbar connector STB 50-3 Al/Cu 87360 SIMBLOCK, black 81003007

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 installers and end-users. This product, from SIMBLOCK by SIMET S.A., combines a solid construction, safe operation, and easy installation. It is dedicated to the construction of electrical switchboards, machines, automation systems, and RES installations.

Construction and application

The STB 50-3 connector allows the connection of wires with a cross-section from 6 mm² to 50 mm² (solid) and from 4 mm² to 35 mm² (stranded with ferrule). Its construction has been designed for effective heat dissipation – the unique shape of the core and the ribbing of the body prevent its accumulation during operation. Thicker walls of the housing provide stability on TS 35 rail and resistance to deformation during tightening of the wires. Allen key screws with a fine thread guarantee a secure and strong connection. Additionally, the connector has a place for a measuring connection, which facilitates control of the connection status in the installation.

Advantages and benefits

• Versatility: The ability to connect aluminum and copper wires in one connector eliminates the need for additional connecting elements.
• Safety: High quality workmanship and UL 486E certification guarantee a safe and durable electrical connection.
• Effective heat dissipation: Prevents overheating of the connection, which increases its lifespan and reliability.
• Easy installation: Allen key screws and a stable construction facilitate quick and precise mounting on TS 35 rail or mounting plate.
• Monitoring capability: Integrated space for a measuring connection allows monitoring of the connection status.
• Durability: Solid construction provides resistance to mechanical damage and corrosion.
• Wide range of applications: Ideal for building electrical switchboards, machines, automation systems, and RES installations.

The STB 50-3 Al/Cu connector is an investment in a safe and reliable electrical installation that will meet the expectations of even the most demanding users.
