KLAUKE Copper Crimp Ring Terminal 4R10 25mm² M10

Secure and reliable electrical connections in power distribution and industrial control systems demand a cable lug that can withstand high currents and harsh environments. The KLAUKE 4R10 copper crimp ring terminal is engineered to create a permanent, low-resistance connection on 25 mm² stranded copper conductors, ensuring optimal conductivity and long-term performance.

Who is it for

This terminal is ideal for electricians, panel builders, and maintenance technicians working on power distribution, control cabinets, and industrial machinery. It suits applications requiring a robust, corrosion-resistant connection that complies with DIN 46235 standards.

Main features

• High-purity electrolytic copper (E-Cu) construction for excellent electrical conductivity.
• Tin-plated surface provides corrosion protection and ensures a reliable crimp.
• Designed for 25 mm² stranded copper conductors with an M10 bolt hole (10.5 mm diameter).
• Hexagonal crimp profile recommended for secure, gas-tight connections.
• Uninsulated design suitable for use with heat-shrink tubing or insulating tape.
• Wide operating temperature range from -55°C to +150°C for demanding environments.
• RoHS compliant and halogen-free for environmental safety.
