Product Features & Engineering Logic
| Key Area | Feature | Advantage | Benefit |
| Certified Safety | UL Listed (E357535) certification. | Meets rigorous international safety and performance standards for electrical connectors. | Peace of Mind: Simplifies compliance for engineering projects and ensures long-term reliability in high-current applications. |
| Max Conductivity | Seamless T2 Copper Body with tin plating. | Eliminates the risk of barrel splitting during crimping and prevents oxidation in humid environments. | Efficiency: Provides a low-resistance connection that minimizes heat buildup and power loss. |
| Heavy-Duty Barrel | 19 mm Barrel Depth for the HUP50 series. | Allows for deeper wire engagement and more secure mechanical crimps. | Pull-out Resistance: Ensures the cable remains securely bonded to the terminal even under mechanical vibration or thermal cycling. |
| Precise Engineering | Optimized Internal/External Diameter ratio ($\Phi 10.0 / 14.0 \text{ mm}$). | Matches 1/0 AWG wire geometry perfectly, reducing gaps within the barrel. | Clean Installation: Achieves a “gas-tight” crimp more easily, protecting internal copper strands from environmental decay. |
FAQs
Q1: What makes the HUP Series different from standard copper lugs?
The HUP series is specifically manufactured and tested to meet UL E357535 standards. This involves rigorous pull tests and conductivity requirements that “generic” terminals may not meet, making them essential for projects requiring official safety inspections.
Q2: Is tin-plating necessary for dry indoor environments?
While copper is a great conductor, it begins to oxidize immediately upon exposure to air. The tin plating on the HUP series provides a protective barrier that prevents “green death” corrosion, ensuring the connection remains low-resistance for the entire lifespan of the equipment.
Q3: Can I use standard hand crimpers for the HUP50 series?
For 50mm² (1/0 AWG) terminals, we strongly recommend using a hydraulic crimping tool with the correct 50mm² die. Because the HUP barrel is thick-walled seamless copper, a hydraulic tool is necessary to achieve the pressure required for a gas-tight bond.
