Product Features & Engineering Logic
| Key Area | Feature | Advantage | Benefit |
| Anti-Rotation Security | Two-hole (Dual Stud) tongue design. | Provides two points of contact, preventing the lug from twisting or loosening under mechanical stress. | System Uptime: Eliminates the risk of “hot spots” caused by loose connections in high-vibration industrial environments. |
| Maximized Conductivity | Pure seamless copper tube body with tin plating. | Provides the lowest possible resistance and prevents galvanic corrosion between dissimilar metals. | Energy Efficiency: Reduces voltage drop across heavy-duty power distribution networks, lowering operational heat. |
| Heavy-Duty Crimp | Extended Long Barrel design (up to 42 mm barrel depth). | Allows for multiple crimps, providing superior wire pull-out resistance and a gas-tight seal. | Critical Safety: Guarantees a permanent connection that exceeds industrial pull-test requirements for mission-critical power. |
| Standardized Fit | 45 mm Hole Spacing (H) for CL60 and CL125 models. | Matches standard industrial busbar bolt patterns (NEMA spacing) perfectly without field modification. | Versatility: Simplifies installation by providing a reliable solution for various dual-bolt equipment interfaces. |
FAQs
Q2: Why use a two-hole CL-2H lug instead of a standard one-hole lug?
Two-hole lugs are required in heavy-duty applications to prevent the terminal from rotating when bolts are torqued. This ensures the contact surface remains flat against the busbar, maintaining electrical integrity and preventing arcing in high-current systems.
Q2: What is the spacing between the two stud holes?
The CL60 and CL125 series feature a standard 45 mm center-to-center spacing (H). This matches standard NEMA spacing for industrial equipment and power distribution busbars.
Q3: Is hydraulic crimping required for the CL-2H series?
For wire sizes like 60 mm2 (1/0 AWG) and 120 mm2 (4/0 AWG), hydraulic crimping is highly recommended. The long barrel design is specifically intended to accommodate two or more crimps for a secure, gas-tight electrical bond.
