Description
- Ceramic sealing structure with H2 mixed gas filled in the chamber, no risk of arc leakage, low&stable contact resistance;
- High value of short-circuit current withstanding to ensure the contacts can be reliably closed when encountering short-circuit current, contributing to no risk of fire and explosion;
- Non-polarity arc extinguishing design that is applicable to a range of scenarios with bidirectional current circuit safely and reliably;
- A set of NO auxiliary contacts is optional;
- Carrying current 800A continuously at 85°C
