Simet STB 50-2 SIMBLOCK Screw Terminal Block for Al/Cu Conductors, Blue

The Simet STB 50-2 SIMBLOCK is a professional-grade screw terminal block engineered for the secure and reliable connection of both aluminum and copper conductors. Designed for demanding electrical environments, this blue terminal block facilitates efficient power distribution in residential, commercial, and industrial electrical systems. Its robust construction ensures long-term stability and consistent electrical contact, adhering to rigorous safety standards for modern electrical installations.

Advantages

This terminal block offers exceptional versatility by supporting both aluminum and copper wiring, which simplifies inventory management and installation processes. The screw-based connection mechanism provides high mechanical strength and low contact resistance, ensuring that connections remain stable even under varying thermal conditions. Its compact design allows for efficient use of space within electrical enclosures, while the distinct blue color aids in clear circuit identification and organization during maintenance or system upgrades.

Suitable for

• Industrial power distribution panels
• Residential electrical service entrance equipment
• Commercial building wiring systems
• Connecting aluminum and copper conductors in electrical cabinets

This terminal block may not be suitable for applications involving extremely high-vibration environments where spring-loaded or specialized vibration-proof connectors might be required. It is also not intended for use with conductors outside of its specified cross-sectional range or for direct exposure to harsh, corrosive outdoor environments without an appropriate protective enclosure.

Key specifications

• Conductor compatibility: Aluminum and Copper
• Connection type: Screw terminal
• Color: Blue
• Application: Power distribution

To use the Simet STB 50-2, ensure the power supply is disconnected before starting any work. Strip the insulation from the conductor to the recommended length, insert the wire into the terminal opening, and tighten the screw to the specified torque to ensure a firm, secure connection. Verify that the wire is held tightly and that no loose strands are exposed outside the terminal block before restoring power to the circuit.

What to consider before purchase

• Verify the cross-sectional area of your conductors matches the terminal capacity
• Ensure the terminal block is compatible with your specific mounting rail or enclosure type
• Check local electrical codes and regulations regarding the use of aluminum conductors

For optimal performance and safety, always use a calibrated torque screwdriver to tighten the terminal screws according to the manufacturer's specifications. Regularly inspect connections in high-load systems to ensure they remain secure over time.
