KLAUKE 28R koperen kerfverbinder voor 95 mm² kabel, DIN 46235, E-Cu

Electricians and panel builders rely on the KLAUKE 28R when they need a secure, permanent connection between two 95 mm² copper conductors. This butt connector is made from electrolytic copper (E-Cu) and is designed for crimping with standard hexagonal dies, ensuring a gas-tight joint that withstands vibration and thermal cycling. It meets DIN 46235, so it fits seamlessly into industrial and utility installations where compliance matters.

Key specifications

• Connector type: Butt connector (Kerbverbinder)
• Material: Electrolytic copper (E-Cu), bare/untreated
• Cable cross-section: 95 mm²
• Connection method: Crimp (hexagonal recommended)
• Standard: DIN 46235
• Operating temperature range: -40 °C to +125 °C
• Voltage class: Low voltage (up to 1 kV, depending on insulation)
• RoHS compliant: Yes
• Halogen-free: Yes
• Colour: Copper

Why choose it

Because it is made from high-purity electrolytic copper, the 28R offers excellent conductivity and corrosion resistance. The absence of surface plating means no risk of galvanic incompatibility with copper conductors. Its robust design and compliance with DIN 46235 make it a trusted choice for professional electrical work, from control cabinets to power distribution.

Ideal use cases

• Connecting stranded or fine-stranded copper conductors in industrial machinery
• Extending or repairing 95 mm² cables in building installations
• Creating permanent, maintenance-free joints in switchgear and transformers
• Use in low-voltage power distribution up to 1 kV

Good to know

For best results, use a hexagonal crimping die matched to the connector size. The bare copper surface may develop a natural patina over time, which does not affect performance. Always ensure the conductors are fully inserted and the crimp is properly formed to achieve a reliable, gas-tight connection.
