Worldwide, air-insulated technology has served as a basis for an established, reliable power supply for more than 100 years. The NXAirS air-insulated medium-voltage switchgear is part of the NXAIR family and the result of many years of experience. The NXAIR family has been launched in 1998, continuously enhanced and individually adapted to the specific market requirements of the different industries and power supply companies. NXAirS 550+ NXAirS 550+ is a compact 12kV medium-voltage air-insulated switchgear with max 550mm in width per panel. Up to 1250A feeder current and 2500A busbar current. Maximum Short-Circuit current up to 31.5kA - 4s. Its width is optimized to 550mm and Internal Arc Classified like IAC A FLR 31.5kA -1s. The compact design reduces the demand of installation space which leads to lower construction investment expenses. NXAirS 550+ can be combined with other NXAirS Typical this enables additional functionalities and a high flexibility.
