Gustav Klauke 12SG10 terminal de cable tubular 240 mm² cobre estañado para conexión de cuadros eléctricos

Electricians and panel builders terminating 240 mm² stranded copper conductors in low-voltage switchgear need a connection that stays secure under vibration and thermal cycling. The Gustav Klauke 12SG10 tubular cable lug provides exactly that, with a tinned electrolytic copper body engineered for reliable, gas-tight crimps.

Key specifications

• Cable cross-section: 240 mm²
• Bolt hole diameter: 13 mm (fits M12 bolts)
• Material: Electrolytic copper (E-Cu), tinned for corrosion resistance
• Standard: DIN 46235
• Connection type: Crimp (hexagonal crimp)
• Conductor compatibility: Stranded copper conductors (Class 2, 5, 6)
• Design: Tubular with inspection hole for visual confirmation of insertion depth
• Insulation: Uninsulated
• Temperature resistance: Up to 120 °C
• Voltage rating: Up to 1000 V
• Inner diameter (cable entry): 20.5 mm
• Outer diameter: 25.5 mm
• Palm thickness: 4 mm

Why choose it

Klauke is a trusted name in electrical connectors, and the 12SG10 lives up to that reputation. The tinned surface not only shields against corrosion but also maintains low contact resistance over time. Its tubular body allows full 360° compression when crimped with the proper die, creating a gas-tight connection that withstands vibration and thermal cycling.

Ideal use cases

• Switchgear and control cabinets
• Power distribution panels
• Industrial automation systems
• Motor and transformer connections
• Any low-voltage application requiring up to 1000 V

Good to know

For installation, use a hydraulic or mechanical crimping tool with the correct hexagonal die. The inspection hole lets you confirm the conductor is fully inserted before crimping, ensuring a proper connection every time.
