Why choose it

The Klauke 25R delivers a reliable, low-resistance connection that maintains integrity under mechanical stress and temperature fluctuations. Its uninsulated design allows for inspection and is ideal for applications where heat-shrink tubing or tape will be applied for insulation. The pure copper construction ensures maximum conductivity and long-term performance in demanding environments.

Ideal use cases

• Joining 35 mm² copper conductors in industrial control panels
• Extending or repairing cable runs in power distribution systems
• Creating permanent splices in motor wiring and switchgear
• Applications requiring a compact, high-current connection

Good to know

The connector is supplied uninsulated; apply suitable insulation such as heat-shrink tubing after crimping. Use a proper crimping tool designed for 35 mm² copper butt connectors to achieve a gas-tight joint. The connector meets the requirements for copper conductors according to DIN 46267.
