• Automation and machinery wiring

When it may not be suitable

This terminal block is specifically designed for grounding applications and should not be used for phase or neutral power distribution where insulation requirements differ. It is also not intended for use in environments with extreme corrosive agents or high-vibration conditions that exceed standard industrial specifications without additional protective enclosures.

Key specifications

• Wire capacity: 10mm2
• Connection type: Screw-clamp
• Color: Yellow-Green
• Mounting: DIN rail compatible
• Application: Grounding

How to use

To install the terminal block, snap it securely onto a standard DIN rail. Strip the insulation from your grounding wire to the appropriate length and insert the conductor into the terminal opening. Tighten the screw using a compatible screwdriver until the wire is firmly clamped. Ensure that the connection is mechanically secure and that there is no exposed copper outside the terminal housing before energizing the system.

What to consider before purchase

• Verify that your wire gauge is compatible with the 10mm2 capacity
• Ensure the mounting rail type matches the terminal block design
• Check local electrical regulations regarding grounding color codes

Usage recommendations

Always use a calibrated torque screwdriver to ensure the screw-clamp is tightened to the manufacturer's recommended specifications to prevent damage to the conductor or the terminal block itself.
