Key specifications

• Connection type: Screw terminal
• Conductor compatibility: Aluminum and Copper
• Mounting: DIN rail
• Color: Green
• Application: Power distribution

How to use

To install the Simet STB 300, mount the terminal block onto a standard DIN rail until it clicks into place. Strip the insulation from your aluminum or copper conductor to the recommended length. Insert the conductor into the terminal opening and tighten the screw to the specified torque to ensure a firm connection. Verify that the wire is held securely before applying power to the circuit.

What to consider before purchase

• Ensure the conductor cross-section is compatible with the terminal block capacity
• Verify that the DIN rail type matches the mounting requirements
• Confirm that the installation environment meets the necessary IP rating standards

Usage recommendations

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