Threaded busbar connector STB 95-3 Al/Cu 87560 SIMBLOCK, grey 81103002

SIMBLOCK Busbar Connectors – Reliable Al/Cu Connections

The STB 95-3 Al/Cu threaded busbar connector is designed for connecting aluminum and copper conductors in electrical installations. The connector's design, combined with high-quality materials, ensures a durable and safe connection, minimizing the risk of overheating and failure. It is an ideal solution for both professional installers and end-users who value reliability and ease of installation.

Design and Application

The STB 95-3 connector is designed for a wide range of applications – from residential construction, through industry, to installations in renewable energy sources. Its threaded design allows for secure and stable mounting of conductors with different cross-sections. Additional space for a measuring connection allows easy access to a control point of the installation, which facilitates diagnostics and monitoring of the connection status. A dedicated OSTB 95 dust cap further protects the connection from dirt and environmental influences.

Advantages and Benefits

• Versatility: The ability to connect aluminum and copper conductors eliminates the need for additional adapters or transitions.
• Safety: High-quality workmanship and UL 486E certification guarantee safe operation even in demanding conditions.
• Durability: Thick walls of the housing ensure stability on TS 35 rail and resistance to mechanical damage during tightening of conductors.
• Easy Installation: Allen key screws with a fine thread provide strong conductor compression, and the ergonomic shape makes it easier for the installer to work.
• Monitoring: Additional space for a measuring connection allows control of the connection status of the conductors and monitoring of the entire installation.
• Dust Protection: The OSTB 95 dust cap protects the measuring connection from dirt.
• Wide Range of Cross-Sections: Support for conductors with a cross-section from 1.5 mm² to 95 mm² (solid) and from 10 mm² to 70 mm² (stranded with ferrule) provides flexibility in choosing the appropriate cables.

Operating Parameters

The STB 95-3 connector is adapted to operate at a rated voltage of up to 1000 V AC/DC. The rated current for copper conductors is 232 A, and for aluminum conductors – 200 A. The possibility of mounting on TS 35 rail or a mounting plate increases its range of applications in various types of electrical installations. The connector's design ensures optimal heat dissipation, which translates into longer life and connection reliability.
