## Long description

Terminal connector Simet STB 50-3 screw-type Al/Cu Simblock black is a rail-mounted connection device designed to join aluminium and copper conductors securely on a mounting rail. The compact, screw-clamp design enables reliable electrical contact for distribution systems and installations where transition between Al and Cu cables or termination on rails is required. The connector's shape and materials are intended to provide stable mechanical fixing and electrical continuity in both industrial and residential wiring applications.
Advantages
The screw-type clamping mechanism provides consistent contact pressure for aluminium and copper conductors, reducing the risk of loose connections. Its compact Simblock housing allows multiple connectors to be installed on standard mounting rails while maintaining a low profile. The connector is suitable for mixed-metal terminations without need for separate adaptors, and the design facilitates straightforward installation and inspection.
Suitable for
 Rail-mounted termination of aluminium and copper conductors
 Electrical distribution blocks in industrial panels
 Transition points between Al and Cu wiring in building installations
 Space-constrained electrical cabinets and enclosures
Key specifications
 Connection type: screw-clamp for Al and Cu conductors
 Mounting: mounting rail compatible

How to use
Mount the connector on a compatible mounting rail and prepare conductor ends according to applicable standards for aluminium and copper cables. Insert the stripped conductor into the appropriate opening and tighten the screw clamp to the manufacturer's recommended torque to ensure reliable contact. Verify mechanical stability and electrical continuity after installation and re-check torque after initial operation if required by local wiring regulations.
Usage recommendations
