Product Features & Engineering Logic
| Key Area | Feature | Advantage | Benefit |
| Connection Precision | Custom-fit for 50mm² (1/0 AWG) wire with an 8.4mm (M8) bolt hole. | Ensures a low-resistance interface and maximum surface contact for standard high-power battery terminals. | Power Safety: Prevents overheating and energy loss in high-demand inverter and solar storage systems. |
| Marine-Grade Protection | Premium Tin-Plated finish over a seamless copper body. | Provides a robust barrier against humidity, salt spray, and acid corrosion compared to bare copper. | Extreme Longevity: Maintains high conductivity in harsh environments like coastal marine applications or outdoor RV setups. |
| Installation Efficiency | Beveled barrel entry design with a 9.5 mm internal diameter. | Guides stranded cables smoothly into the barrel without fraying or loose wire strands. | Professional Termination: Saves time during assembly and guarantees a consistent, gas-tight crimp every time. |
| Industrial Durability | Manufactured using a seamless high-conductivity copper tube. | Withstands extreme mechanical stress and high-pressure hydraulic crimping without cracking. | Critical Reliability: Ideal for high-vibration environments such as vehicle alternators, generator sets, and industrial control panels. |
FAQs
Q1: Can the SC50-8 lug be used with both solid and stranded 1/0 AWG wire?
It is primarily designed for stranded Class 2 conductors commonly found in battery and inverter cables. The 9.5mm internal barrel diameter ensures a secure fit for flexible cable classes.
Q2: What is the recommended crimping tool for this lug?
You will need a hex crimper or hydraulic crimping tool capable of exerting 6-10 tons of force. Set the die to 50mm² (or 1/0 AWG). The seamless copper barrel ensures a solid, gas-tight crimp when used with the correct tool.
Q3: Why choose the SC series for marine applications?
The SC series features a closed-end design to protect the conductor from moisture and corrosion, while the tin plating provides superior resistance to salt spray and acid.
