Product Overview
Power Xpert XGIS Air switchgear combines safety, reliability, and space savings without compromising functionality. It features a cast aluminum tank-type gas chamber with superior pressure capacity, housing the breaker, disconnector, and busbar in eco-friendly gas. The cast-type busbar ensures excellent conductivity and strength. For safety, an arc protection system discharges gas through a pressure relief channel during faults. The IP4X front-accessible enclosure allows safe operations and metering device mounting from the front. This robust design delivers exceptional value for modern power distribution needs.
