Technical specifications

Customization guide

Adjustable rated current (25A–150A) and voltage compatibility (12V–48V DC) allow customization to match specific power requirements. For high-amperage applications (e.g., electric vehicle charging systems), select higher-rated models (e.g., 100A–150A).

Supplier's note

1. Technical Breakthroughs:

   • IP67 Waterproofing: Enables deployment in outdoor or marine environments without risk of short circuits.
   • Auto-Reset with BCD Curve C: Reduces downtime by instantly resetting after minor overloads while preventing nuisance tripping.
   • Copper Contacts: 20% lower resistance than aluminum, ensuring efficient power flow in high-current setups.

2. Optimal Version Selection:

   • Base Model (30A–60A): Ideal for standard automotive systems (e.g., LED lighting, audio systems) where moderate current handling is sufficient.
   • Advanced Model (70A–100A): Tailored for heavy-duty industrial machinery or marine equipment requiring higher power resilience.
   • Pro Model (120A–150A): Designed for high-power applications like EV charging stations or solar inverters, where triple the industry-standard chemical resistance ensures longevity in corrosive environments.

With the Pro version’s 150A capacity, you can safely power high-demand systems while its copper contacts reduce energy loss by 20% compared to competitors. Pair it with 48V DC systems to maximize efficiency in industrial automation setups.
