## Summary description

Simet STB 50 is a threaded rail terminal connector designed for Al/Cu conductors, model 81001002. The connector provides mechanical and electrical connection between aluminium and copper conductors, featuring a threaded design for secure clamping and a grey insulated body. Suitable for electrical installations where mixed-metal conductor termination is required.

## Long description

Simet STB 50 threaded rail terminal connector is designed to provide a reliable mechanical and electrical connection between aluminium and copper conductors. The grey insulated body and threaded clamping system allow secure termination of mixed-metal conductors in electrical installations where aluminium-to-copper transitions are required. The connector is suitable for fixed installations and supports standard conductor cross-sections used in distribution and power circuits.
Advantages
The threaded clamping mechanism ensures strong mechanical retention and consistent electrical contact pressure, reducing the risk of loosening over time. The insulated grey housing offers basic protection against accidental contact and helps organize conductor routing. Engineered for aluminium and copper compatibility, the connector minimizes galvanic corrosion risk when used as specified and simplifies termination processes in mixed-metal wiring projects.
Suitable for
Transitioning between aluminium and copper conductors in power distribution
Fixed electrical installations in residential and commercial panels
Applications requiring secure, threaded clamping termination
Key specifications
Type: Threaded rail terminal connector for Al/Cu conductors
Insulation: Grey insulated body for basic contact protection
Connection method: Threaded clamp providing mechanical and electrical contact
Compatibility: Designed for aluminium and copper conductors of corresponding cross-sections
Mounting: Rail-mounted style suitable for distribution and control panels
How to use
Strip conductor insulation to the recommended length, insert aluminium and copper conductors into the designated clamping points, and tighten the threaded clamp to achieve secure mechanical and electrical contact. Follow torque recommendations from installation standards or project specifications to avoid over- or under-tightening. Ensure the connector body is mounted on the appropriate rail and that conductors are routed to avoid mechanical strain on the termination.
Usage recommendations
Use the Simet STB 50 connector in installations that follow local electrical codes and manufacturer guidance for aluminium-to-copper connections. Verify conductor cross-sections and apply proper torque and anti-oxidation measures for aluminium conductors where required by standards.
