GE’s Arc Vault system extinguishes arc flashes as opposed to exhausting them. Traditional arc-resistant switchgear is designed not to eliminate the flash but to muffle it, exhausting its energy through a chimney or plenum and providing no protection for equipment. Arc Vault can stop an arcing fault in less than 8 milliseconds, a fraction of the time that traditional systems need to stop a flash. The system reduces downtime, decreases switchgear damage, and can be added as a retrofit. The 316L stainless steel housing is designed for hazardous areas and extreme environments, including offshore, and withstands corrosion, high humidity, and salinity.
