NXAIR: Air-insulated medium-voltage switchgear

Empower your sustainability journey

Air-insulated switchgear for primary distribution

NXAIR air‑insulated medium‑voltage switchgear delivers safety, reliability and sustainability for modern power distribution. Using natural air instead of SF6, it eliminates greenhouse gases and simplifies recycling. Certified with Siemens Ecotech 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.

Advance sustainable design

Replace SF6 with air insulation and integrate LPIT sensors for reduced material use, improved recyclability and compliance with IEC standards.

Featured capabilities

Leverage air insulation

Use natural air and vacuum interrupters to avoid SF6 and F‑gases, improve sustainability and streamline recycling across the product’s long service life.

Integrate LPIT sensors

Enable precise measurement and digital connectivity with IEC 61869‑compliant current and voltage sensors embedded in NXAIR bushings.

Digitize condition monitoring

Connect SICAM A8000 and Electrification X to track asset health, enable remote support and predictive maintenance that reduces unplanned downtime.
