SF₆-free. Future-ready. Fault-proof
RM AirSeT is Schneider Electric’s pure-air insulated RMU that brings green performance, digital intelligence, and rock-solid MV safety up to 24 kV
Explore MoreOld RMUs add risk. SF₆ adds cost.
Networks struggle when toxic gases age, joints overheat unseen, moisture creeps in, and arc safety isn’t guaranteed. That means downtime, environmental penalties, and unpredictable failures.
Meet RM AirSeT — clean insulation, strong protection, smart control
RM AirSeT replaces SF₆ with pure air and vacuum switching — cutting emissions while keeping full MV performance. Its stainless-steel IP67 tank is sealed for 40 years, immune to dust, moisture, and pollution. The CompoDrive mechanism delivers 10,000+ operations with familiar three-position logic for easy adoption. Modular units let you configure switches, breakers, fuses, and smart sensors, making it ideal for modern secondary distribution networks.
