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.

3.20A, 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. Non-polarized load requirement

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