  • 1.Characteristic

    1. Ceramic brazed sealing eliminates the risk of arc leakage, ensuring no fire or explosion occurs.

    2. The potting process uses a gas primarily composed of hydrogen, effectively preventing contact oxidation and burnout, resulting in low and stable contact resistance; the contact area meets the IP67 protection rating.
    Long-term current carrying capacity: 3,400 A at 85°C

    4. The insulation resistance reaches 1000 MΩ (1500 V DC), with a withstand voltage of 4 kV between contacts and the coil, complying with IEC 60664-1 requirements.

    5. The load has no polarity requirement, but coil drive requires specific polarity.

    6. Energy storage applications with safety compliance requirements for voltages ≤1500 VDC
