Crimped Copper Ring Terminal Ergom KM 35/8 (E11KM-01010104000)

Crimped copper ring terminal Ergom KM 35/8 is a plated copper electrical terminal designed to provide a reliable bolted connection for power and grounding applications. The terminal features a circular eye that fits over bolts or studs and a crimp section sized for secure attachment to conductor ends. It is intended for use in electrical installations, battery connections and power distribution systems where a firm mechanical and low-resistance electrical contact is required.

Advantages

The Ergom KM 35/8 ring terminal combines corrosion-resistant plated copper with a shaped eye for consistent bolt seating, offering stable conductivity and mechanical strength. Its crimp section is engineered to accept the specified conductor cross-section and create a firm, vibration-resistant joint when crimped correctly. The simple design facilitates quick installation and inspection, and the plated finish improves long-term contact reliability in typical indoor electrical environments.

Suitable for

• Grounding and earthing connections in electrical panels
• Battery terminal connections in stationary or automotive applications
• Power distribution bars and busbar connections
• Industrial equipment and control cabinets requiring bolted conductor terminations

When it may not be suitable

This ring terminal is not intended for use with conductors that exceed the recommended cross-sectional range for the crimp section; using oversized conductors can result in poor crimp quality and unreliable connection. It is also not designed for direct exposure to highly corrosive or submersible environments without additional protective measures.

Key specifications

• Material: copper with protective plating
• Ring internal diameter: suitable for 8 mm bolt or stud
• Conductor connection: crimp-type barrel sized for 35 mm² conductor
• Application: bolted electrical connections, grounding, battery and power distribution

How to use

Strip the conductor to the appropriate length, insert the bare conductor fully into the crimp barrel, and use a suitable crimping tool sized for the terminal and conductor cross-section to form a secure mechanical joint. Place the ring over the bolt or stud and tighten the fastener to the torque recommended for the bolt and terminal material to ensure reliable electrical contact. Inspect the crimp and bolted connection for proper compression and alignment after assembly.

What to consider before purchase

• Confirm the conductor cross-section matches the terminal’s crimp barrel capacity (35 mm²)
• Verify the ring internal diameter fits the bolt or stud size used (8 mm)
• Ensure compatibility with the installation environment and any required corrosion protection
• Choose an appropriate crimping tool and, if required, heat-shrink or insulating covers for added protection

Usage recommendations

Use a calibrated crimping tool rated for the conductor size, and follow torque specifications for bolted connections. For outdoor or harsh environments, apply additional protective measures such as insulating boots or anti-corrosion treatments to extend service life.
