When the load break switch opens under load conditions, an electric arc forms between the contacts. The arc extinguish chamber rapidly cools and elongates the arc using gas generation and airflow control mechanisms, reducing ionization and extinguishing the arc safely at current zero crossing. This design significantly improves switching reliability and protects the switch contacts from excessive erosion.<\/p>\n
