The revolutionary SM AirSeT MV switchgear marks a bold move away from SF₆ gas to the best gas: pure air.
It draws from the legacy of the established SM6 switchgear, with an installed base that exceeds 1.5M, and uses proven and reliable vacuum technology while keeping all functionalities and connectivity for a no-compromise approach.

SM AirSeT features

-
Green switching
1Pure air and vacuum technology (Shunt Vacuum Interruption) -
CompoDrive switching mechanism
2Engineered from high-tech composite materials and delivering mechanical endurance improved to accommodate up to 10,000 operations. -
Offer range
3Switch, circuit breaker, metering, riser and the uniquely sustainable switch-fuse. -
Circuit breaker monitoring
4Monitor circuit breaker wear and tear in real time and be notified on when is the best time to perform its maintenance. -
Thermal monitoring
5Wireless thermal sensors to monitor the quality of power connections, prompting diagnosis of potential faults, and reducing downtime and fire risks. -
Environmental monitoring
6Wireless humidity sensors to monitor environmental conditions, helping prevent fast ageing and optimising maintenance costs. -
QR code
7Quickly connect to SM AirSeT and get access to the digital logbook, manuals and support, saving operational time and effort. -
Arc-flash detection
8Optical sensors allowing the relay and the circuit breaker to provide fast internal arc clearance, decreasing operator and equipment risk, while reducing equipment damage in case of internal arcs. -
Nearby control
9Operate SM AirSeT with a single tap from a smart device, helping operators to keep a safer distance.
