## Long description

The Phoenix Contact USLKG 5 is a professional-grade 2-conductor protective earth terminal block engineered for reliable grounding in diverse electrical installations. This component provides a secure mechanical and electrical connection to the mounting rail, ensuring safety and stability in industrial control cabinets and power distribution systems. Its robust design supports a wide conductor cross-section range, making it a versatile choice for grounding applications requiring high mechanical integrity.
Advantages
This protective earth terminal block offers exceptional reliability through its high-quality construction and secure clamping mechanism. The standard green and yellow color coding allows for immediate visual identification of the grounding point, which simplifies maintenance and troubleshooting processes. Its compact design optimizes space within control panels, while the high-grade materials ensure long-term performance even in demanding industrial environments. The terminal block is designed to maintain consistent contact pressure, preventing loose connections and ensuring a low-resistance path to the ground.
Suitable for
Industrial control cabinets
Power distribution systems
Grounding of electrical circuits
Automation and control panels
When it may not be suitable
This terminal block is specifically designed for protective earth (PE) grounding applications and should not be used as a standard feed-through terminal for carrying phase or neutral currents. It is not intended for use in environments where the required insulation voltage exceeds 690 V without appropriate additional measures.
Key specifications
Conductor cross-section range: 0.2-6 mm²
Number of conductors: 2
Color: Green and yellow
Rated voltage: Up to 690 V
Mounting type: DIN rail
How to use
To install the USLKG 5, snap the terminal block onto the standard mounting rail until it clicks securely into place. Insert the stripped conductor into the clamping unit and tighten the screw to the specified torque to ensure a firm connection. When aligning this terminal block with a feed-through terminal block of the same shape, ensure that an end cover is interposed if the insulation voltage exceeds 690 V to maintain proper electrical safety standards.
What to consider before purchase
Verify the conductor size matches the 0.2-6 mm² range
Ensure the mounting rail type is compatible
Check if an end cover is required for your specific assembly configuration
Confirm the grounding requirements of your electrical system
Usage recommendations
Always ensure that the mounting rail is properly grounded to the main protective earth system of the installation to guarantee the effectiveness of the terminal block.
