  • 1.Characteristic

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

    2. The sealing process uses a gas primarily composed of hydrogen, effectively preventing contact oxidation and burnout, ensuring low and stable contact resistance, with the contact area meeting IP67 protection requirements.

    3.250A, Long-term current carrying capacity at 85°C

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

    5. The load has no polarity requirement, whereas the coil drive has a polarity requirement.

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