1.Characteristic

● Ceramic brazing seal eliminates the risk of arc leakage, ensuring no fire or explosion.

● Encapsulation with a hydrogen-based gas effectively prevents contact oxidation and burn-off, resulting in low and stable contact resistance.

The contact section meets IP67 protection standards.

● 300A 85°C long-term current carrying capacity.

● Insulation resistance reaches 1000MΩ (1000VDC), with a withstand voltage of 3kV between contacts and coil, complying with IEC 60664-1 requirements.
