NXAirS Lp Authorization Cabinet
Product Introduction
NXAirS is the latest compact air insulated switchgear launched by SIMENS. The NXAirS switchgear meets the latest standards and has significant advantages, such as easy operation and rich global operation experience, providing the highest level of safety protection for users. The NXAirS switchgear has achieved internal arc rating IAC A FLR, loss of operational continuity category LSC 2B, and partition rating PM. This makes the NXAirS switchgear suitable for various installation methods, ensuring the personal safety of operators to the greatest extent possible. NXAirS removable metal armored medium voltage switchgear is a switchgear installed indoors. After type testing, it meets the requirements of GB3906 and DL404 (insulation), IEC62 271-200/VDE0671-200 (formerly IEC60298 and VDE0670-6) and other standards.
