Screw terminal rail connector STB 95-3 Al/Cu 87560 SIMBLOCK, green 81103005

Rail terminal blocks – reliable Al/Cu connections

The STB 95-3 rail terminal block is designed for connecting aluminum and copper conductors, providing a safe and durable connection in electrical installations. The terminal block's design focuses on ease of installation and reliable operation, which will be appreciated by both professional installers and end-users. Made of high-quality materials, it guarantees a stable connection even under high loads.

Construction and application

The STB 95-3 terminal block allows connection of conductors with cross-sections from 6 mm² to 95 mm² (solid wire) and from 10 mm² to 70 mm² (stranded wire with ferrule). Additionally, it has a dedicated space for a measuring connection, which facilitates monitoring the connection status and installation. This solution is particularly useful in systems requiring precise measurement of electrical parameters. The terminal block is compatible with TS 35 rails and mounting plates, providing flexibility in choosing the installation location.

Advantages and benefits

• Versatility: The ability to connect aluminum and copper conductors eliminates the need for additional adapters or intermediate elements.
• Safety: High-quality workmanship and a solid construction guarantee a stable connection, minimizing the risk of short circuits and open circuits.
• Easy installation: Hex-head screws with a fine thread provide strong conductor clamping, and the ergonomic shape facilitates the installer's work.
• Additional space for measuring connection: Allows convenient access to the measurement point without the need to disassemble the connection. Dedicated OSTB 95 dust cover further protects this area from contamination.
• Temperature resistance: The special core shape and ribbing of the housing promote heat dissipation, preventing overheating of the connection.
• Durability: Thick housing walls ensure the stability of the terminal block on the TS 35 rail and resistance to mechanical damage during conductor tightening.
• Protection against contact with live parts: The shape of the housing minimizes the risk of accidental contact with energized components during installation and operation.

The use of SIMBLOCK terminal blocks ensures reliable, durable and safe electrical conductor connections in construction, machine building, production process automation, electrical switchboards and devices producing energy from renewable sources.
