Primary switchgear NXAIR series

medium-voltageair-insulatedcompact

NXAIR air-insulated medium-voltage switchgear uses proven air technology for reliable power distribution, high personal safety, and low operational costs. NXAIR air‑insulated medium‑voltage switchgear delivers safety and reliability for modern power distribution. Using natural air instead of SF₆, it eliminates greenhouse gases and simplifies recycling. Certified with Siemens Ecotech label for environmental responsibility, NXAIR meets IEC 62271‑200 standards and offers robust arc‑fault containment, interlocked operations and pressure relief for maximum protection. With digital monitoring, vacuum circuit breakers and long service intervals, it reduces lifecycle costs while ensuring high availability. Now enhanced with Low Power Instrument Transformers (LPITs) – tomorrow’s technology – integrating IEC 61869‑compliant sensors and SIPROTEC 5 relays for advanced digitalization and future‑ready performance. Product portfolio: NXAIR – up to 17.5 kV up to 40 kA NXAIR – up to 17.5 kV 50 kA NXAIR M – 24 kV up to 25 kA NXAIR C – up to 24 kV up to 25 kA NXAIR H – 36 kV up to 31.5 kA Key benefits Protect people and assets Minimize risk with interlocked operations, pressure relief and IEC type‑tested arc‑fault containment for dependable personal and operational safety. Reduce lifecycle costs Cut maintenance with vacuum breakers and >10‑year service intervals, extend equipment life and lower total cost through factory‑finished reliability.
