Component Specifications

Definition
A grounding lug is a specialized electrical component designed to provide a reliable, low-resistance path to earth ground within strain relief or backshell systems. It typically consists of a metal terminal with a hole for mounting and a clamping mechanism to secure grounding wires. In industrial applications, it ensures electrical safety by preventing static buildup, reducing electromagnetic interference (EMI), and protecting against electrical faults in machinery and equipment.
Working Principle
The grounding lug operates on the principle of electrical continuity, creating a direct metallic connection between the equipment chassis or cable shield and the grounding system. When installed, it bonds conductive parts to earth ground, allowing fault currents or static charges to safely dissipate, thereby preventing electric shock hazards and equipment damage.
Materials
Typically made from highly conductive and corrosion-resistant materials such as copper alloys (e.g., brass, bronze), aluminum, or stainless steel. May include plating like tin, nickel, or silver for enhanced conductivity and durability.
Technical Parameters
  • Clamping Force 10-30 N
  • Current Rating Up to 50 A
  • Voltage Rating Up to 600 V
  • Temperature Range -40°C to 105°C
  • Mounting Hole Diameter 3-8 mm
Standards
ISO 9001, IEC 60352, UL 486A
