Klauke 104R12 Tubular Cable Lug 25 mm² M7 Electro-Tinned Copper Crimp Connector

For secure, low-resistance terminations on 25 mm² copper conductors, this standard tubular cable lug delivers a gas-tight crimp connection that withstands vibration and thermal cycling. The electro-tinned electrolytic copper body ensures excellent conductivity and corrosion resistance, while the inspection hole allows visual confirmation of full conductor insertion before crimping.

Advantages

Manufactured from high-purity electrolytic copper (E-Cu) with an electro-tinned surface, the lug offers superior solderability and protection against oxidation. The crimp connection method guarantees a durable, gas-tight joint that maintains performance under demanding conditions. An inspection hole provides a simple way to verify correct conductor insertion, reducing installation errors.

Suitable for

• Connecting 25 mm² copper cables to busbars, studs, or terminals with M7 bolts.
• Use in control cabinets, switchgear, and power distribution systems.
• Applications requiring compliance with DIN 46235 and RoHS standards.
• Operating temperatures from -55°C to +150°C and voltages up to 1000 V.
