• Main supply line terminations

When it may not be suitable

This terminal block is not intended for use with flexible fine-stranded wires unless appropriate ferrules are applied to ensure a secure grip. It is also not suitable for high-frequency signal transmission or applications requiring specialized waterproof or explosion-proof enclosures.

Key specifications

• Compatible with aluminum and copper conductors
• Screw-type connection mechanism
• Robust industrial-grade housing
• Designed for secure power distribution

How to use

To use the Simet STB 300, first ensure the power supply is disconnected. Strip the insulation from the conductor to the required length, ensuring the wire is clean and free of oxidation. Insert the conductor into the terminal opening and tighten the screw firmly to the specified torque to ensure a solid mechanical and electrical connection. Verify that the wire is held securely before restoring power to the circuit.

What to consider before purchase

• Verify the cross-section compatibility of your conductors
• Ensure the terminal block matches the current rating of your system
• Confirm the mounting space available in your distribution board

Usage recommendations

Always follow local electrical codes and regulations during installation. Regularly inspect terminal connections for tightness, especially in systems subject to thermal expansion or vibration.
