EM Group Tubular Ring Terminal 16mm² M10 Tinned Copper

The EM Group tubular ring terminal is a high-quality electrical component engineered for the secure termination of 16mm² conductors. Constructed from premium tinned copper, this terminal offers superior electrical conductivity and long-term protection against oxidation and environmental corrosion. Designed for use with M10 bolts, it provides a robust and reliable connection point essential for professional electrical systems, power distribution panels, and grounding setups.

Advantages

The primary benefit of this tubular ring terminal lies in its material composition, as the tinned copper ensures minimal resistance and maximum current flow efficiency. The tubular design allows for a tight, uniform crimp, which enhances the mechanical strength of the connection and prevents wire pull-out. Furthermore, the tin plating provides a durable barrier against moisture and chemical exposure, making it suitable for demanding industrial environments where connection integrity is critical.

Suitable for

• Power distribution cabinets and switchgear
• Grounding and earthing systems
• Industrial machinery electrical wiring
• Battery cable terminations
• Professional electrical installation projects

When it may not be suitable

This terminal is specifically sized for 16mm² conductors and an M10 stud; it will not provide a secure connection if used with smaller or larger wire gauges. It is also not intended for high-vibration environments without additional strain relief or for applications requiring insulation, as this is a non-insulated terminal.

Key specifications

• Conductor cross-section: 16mm²
• Stud size: M10
• Material: Tinned copper
• Terminal type: Tubular ring

How to use

To install the terminal, first strip the insulation from the end of the 16mm² conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Using a professional crimping tool designed for tubular terminals, apply sufficient pressure to create a permanent, gas-tight connection. Once crimped, place the ring end over the M10 bolt and secure it firmly with a nut and washer to ensure optimal contact.

What to consider before purchase

• Verify that your conductor cross-section is exactly 16mm².
• Ensure the mounting surface accommodates an M10 bolt.
• Check if your crimping tool is compatible with tubular copper terminals.
• Consider the need for heat-shrink tubing if insulation is required for your specific application.

Usage recommendations

Always use a calibrated crimping tool to ensure the integrity of the connection. Avoid over-tightening the nut on the M10 stud to prevent damage to the terminal or the mounting surface.
