SF6 room IEC specifications

The UniSec AirPlus utilizes an eco-efficient version of the HySec, a combined circuit breaker and disconnector. With ABB's AirPlus™ insulation gas in the disconnector device, the global warming potential is reduced to less than 1 - a reduction of more than 99.99% compared to the conventionally used sf6-gas.
