## Long description

Simet threaded rail connector Al/Cu STB 50 Simblock blue, model 81001003 is a mechanical connector designed to join or terminate aluminum and copper busbars or cables. The product features a threaded connection that provides stable mechanical fastening and electrical contact for mixed-conductor installations. Its blue finish identifies the Simblock series and supports easy visual recognition in distribution boards, electrical panels and industrial switchgear environments.
Advantages
The connector offers reliable electrical continuity between dissimilar conductors while maintaining a compact footprint for space‑constrained panels. The threaded fastening ensures firm mechanical clamping and facilitates secure torque application during installation. Constructed for mixed Al/Cu use, the design helps reduce galvanic corrosion risks when connections are made according to recommended procedures. The visible blue finish improves component identification and organization within switchgear assemblies.
Suitable for
 Joining aluminum and copper busbars in distribution boards
 Terminating Al and Cu cables in electrical panels
 Connections inside industrial switchgear and control cabinets
 Retrofit or upgrade work where dissimilar conductor joining is required
Key specifications
