For users with a green focus, UniSec AirPlus is also available - offering the same known dimensions, safety and reliability. 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.
