Suitable for

• Industrial electrical distribution panels
• Residential electrical wiring systems
• Connecting aluminum and copper power cables
• General electrical maintenance and infrastructure projects

When it may not be suitable

This terminal block is not intended for use in environments with extreme chemical exposure or high-moisture conditions unless housed in an appropriately rated enclosure. It is also not suitable for applications requiring quick-connect or push-in termination methods, as it relies specifically on screw-type fastening.

Key specifications

• Material compatibility: Aluminum and Copper conductors
• Connection type: Screw terminal
• Color: Green
• Application: Electrical distribution

How to use

To use the Simet STB 50-2, ensure the power supply is disconnected before starting any work. Strip the insulation from the end of the conductor to the appropriate length. Insert the conductor into the terminal opening and tighten the screw firmly using a compatible screwdriver to ensure a secure mechanical and electrical connection. Verify that the wire is held tightly and cannot be pulled out. Ensure that the terminal block is properly mounted within the distribution board or enclosure.

What to consider before purchase

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

Usage recommendations

Always use a calibrated torque screwdriver to tighten the terminal screws to the manufacturer's specified torque settings to prevent damage to the conductor or the terminal block itself.
