Designed for a 50mm² conductor cross-section and featuring an M8 stud hole, this terminal provides a secure and permanent connection for power distribution and heavy-duty electrical systems. Its robust construction ensures optimal electrical conductivity and mechanical integrity, making it a reliable choice for critical wiring tasks where safety and durability are paramount.

Advantages

This ring cable lug offers exceptional mechanical stability and low contact resistance, which are essential for maintaining the efficiency of electrical circuits. The non-insulated design allows for versatile installation options, particularly in environments where specific heat-shrink tubing or insulation methods are required. Its high-quality material composition ensures resistance to vibration and thermal stress, providing a long service life even in challenging operational conditions. The precise manufacturing standards of Weidmüller guarantee a consistent fit and reliable performance across various industrial applications.

Suitable for

• Electrical control panels and switchgear
• Power distribution systems
• Heavy-duty industrial machinery
• Grounding connections
• Battery and power supply cabling

When it may not be suitable

This product is not intended for use in environments requiring pre-insulated terminals for quick installation or where the application involves conductors smaller or larger than the specified 50mm² cross-section. It is also not suitable for direct exposure to highly corrosive environments without additional protective measures.

Key specifications

• Conductor cross-section: 50mm²
• Stud size: M8
• Material: High-conductivity copper
• Design: Non-insulated ring terminal
• Application: Industrial electrical wiring

How to use

To install the cable lug, first strip the insulation from the end of the 50mm² conductor to the appropriate length. Insert the conductor fully into the barrel of the lug. Use a professional-grade crimping tool specifically calibrated for 50mm² non-insulated terminals to ensure a gas-tight, mechanical crimp. Once crimped, the lug can be secured to the M8 stud using a compatible nut and washer, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Verify the conductor size matches the 50mm² specification exactly.
• Ensure the M8 stud size is compatible with your connection point.
• Confirm that the appropriate crimping tool for non-insulated lugs is available.
• Assess whether additional insulation, such as heat-shrink tubing, is required for your specific installation safety standards.

Usage recommendations

Always ensure that the crimping process is performed correctly to prevent overheating or high contact resistance. Regularly inspect connections in high-vibration environments to ensure that the fastening hardware remains secure over time.
