Why choose it

Gustav Klauke is synonymous with precision-engineered connection technology. This cable lug delivers consistent crimping with no sharp edges, reducing the risk of insulation damage. The bare copper surface provides excellent conductivity, and the inspection hole allows quick visual confirmation that the conductor is fully inserted, ensuring a durable and reliable connection every time.

Ideal use cases

• Industrial control panels and switchgear
• Power distribution and motor connections
• Grounding and earthing systems
• Renewable energy installations, including solar and wind

Good to know

Use a suitable crimping tool with the correct die for 50 mm² conductors to achieve a consistent, gas-tight connection. The lug is compatible with standard M10 bolts, and the 10.5 mm hole diameter simplifies installation. For best results, pair with Klauke crimping tools designed for this profile, and always follow the recommended crimping procedure for maximum electrical and mechanical performance.
