How to use

To use the Simet STB 300-2, ensure the power supply is disconnected before starting any installation work. Strip the insulation from the conductor to the appropriate length as specified by local electrical standards. Insert the conductor into the terminal opening and tighten the screw firmly to secure the wire. Verify that the connection is tight and that no loose strands are visible. Ensure the terminal block is securely mounted to the DIN rail or base plate before applying power to the circuit.

What to consider before purchase

Verify the cross-section of your conductors matches the terminal capacity
Ensure the installation environment is compatible with the terminal block specifications
Check local electrical regulations regarding the use of aluminum conductors

Usage recommendations: Regularly inspect the screw connections during routine maintenance to ensure they remain tight, especially when using aluminum conductors which may be subject to thermal expansion and contraction.
