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 250A continuously at 85°C;
