How to use

To use the Simet STB 50-3, ensure the power supply is disconnected before starting any installation work. Strip the insulation from the conductor to the appropriate length as required by the terminal design. Insert the conductor into the terminal opening and tighten the screw firmly using a calibrated screwdriver to achieve the recommended torque. Verify that the connection is secure by gently pulling on the wire before closing the enclosure.

What to consider before purchase

• Verify the cross-section of your conductors matches the terminal capacity
• Ensure the terminal is compatible with the specific type of aluminum or copper wire used
• Check local electrical regulations regarding the use of aluminum conductors in your specific installation

Usage recommendations

Always use a torque-limiting screwdriver to ensure the connection meets the manufacturer's specifications, preventing damage to the terminal or the conductor.
