Supplier's note

  1. Technical Breakthroughs:

    • Gold-Plated Contacts: Reduces contact resistance by 20% compared to standard silver-plated relays, minimizing heat buildup.
    • 30A Continuous Rating: Outperforms industry benchmarks (typically 25A) for heavy-duty cooling fan applications.
    • OE-Specific Design: 100% fitment compatibility with Toyota/Lexus models, eliminating installation guesswork.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard Toyota/Lexus vehicles with stock cooling systems.
    • Advanced Model: Recommended for modified engines or high-temperature environments (e.g., off-road vehicles).
    • Pro Model: Best for racing or industrial fleets requiring extreme durability and thermal resistance.

With gold-plated contacts, you can ensure long-term reliability in harsh automotive environments. The Pro model’s 40A capacity and +150°C tolerance enable safe operation in extreme conditions, such as prolonged high-speed driving or heavy towing.
