Threaded busbar connector STB 50 Al/Cu 87310 SIMBLOCK, brown 81001015

Rail-mounted threaded connectors for Al/Cu connections

The STB 50 Al/Cu threaded rail connector is a reliable solution for connecting aluminum and copper wires, designed for demanding electrical installations. This product, from SIMBLOCK by SIMET S.A., combines solid construction, safe operation, and easy installation. It is dedicated to both professional installers and end-users looking for reliable and durable connections.

Design and application

The STB 50 connector is designed for mounting on TS 35 rail or a mounting plate. It allows connection of two wires with a cross-section from 6 mm² to 50 mm² (solid) or from 4 mm² to 35 mm² (stranded with ferrule). Its design allows for safe connection of aluminum and copper wires, eliminating the risk of electrochemical corrosion, which often occurs with direct contact of these metals. Therefore, the connector finds wide application in construction, industry, automation, and renewable energy installations.

Advantages and benefits

• Versatility: The ability to connect aluminum and copper wires in one connector saves time and costs associated with using separate connectors for each material.
• Safety: High-quality materials and precise workmanship guarantee a stable and safe electrical connection, minimizing the risk of short circuits and overheating.
• Effective heat dissipation: The unique shape of the core and the ribbing of the housing ensure effective heat dissipation generated during operation, which translates to a longer connection life.
• Durability: Thick housing walls prevent deformation during wire tightening, ensuring stability on the TS 35 rail. Imbus screws with a fine thread increase the clamping force.
• Easy installation: The ergonomic shape makes it easier for the installer to work, and the color of the housing (brown) helps to identify the connected wires.
• Certificates: The product has UL 486E certificates and CE, RoHS and REACH declarations of conformity, which confirms its high quality and safety.
• Rated voltage: Ensures safe operation at a rated voltage of up to 1000 V AC/DC.
• Rated current: Allows current transmission up to 150 A for both aluminum and copper wires.

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