  • 1.Characteristic

    1. Ceramic brazed seal eliminates the risk of arc leakage, ensuring no fire or explosion.
    2. Hydrogen-based gas filling effectively prevents contact oxidation and burn-out; contact resistance is low and stable, and the contact assembly meets IP67 protection standards.
    3. Capable of carrying 400A current at 85°C for extended periods.
    4. Insulation resistance reaches 1000 MΩ (1000 VDC), and the withstand voltage between contacts and coil is 3 kV, complying with IEC 60664-1 requirements.
