Ensures peace of mind For power supply companies and industrial plants, the platform concept of the NXAirS family introduced at all production locations has very concrete advantages: Smooth operation, exemplary availability and optimal safety. • No handling of insulating gas and low and high pressure monitoring required • As insulating medium, air is always available • Factory-assembled, type-tested switchgear according to IEC 62271-200 , GB 3906 and DL/T 404 • Platform concept introduced worldwide, centrally controlled development, local manufacture • Use of standardized block-type current transformers...

Customer benefit Saves lives All switchgear types of the NXAirS family are approved with internal arc classification IAC A FLR, loss of service continuity category LSC 2B and partition class PM. This makes them suitable for universal installation, meeting the higher requirements regarding personal safety. In addition the arc quenching device SIQuench can be selected for protection beyond the standards. • All operations with closed high-voltage door including manual operation of vacuum circuit-breaker • Metallic enclosure, earthed shutters and partitions • Internal arc classified switchgear according...

Increases productivity Properties such as modular design, type tests of the switching devices in the switchgear, confinement of an internal arc to the respective compartment, and thus high operational reliability, contribute to optimum operation and a remarkable increase of productivity. • Loss of service continuity category LSC 2B • Positively driven shutters • Use of standardized block-type current transformers • Cable testing without isolating the busbar • Functions such as establishment of the isolating distance, ' as well as feeder and busbar earthing, can be completely controlled from remote...

Customer benefit Saves money The compact design of the NXAirS family pays twice for owners due to the use of the Siemens 3AE vacuum circuit-breaker. On the one hand, building costs can be reduced in this way, and on the other hand, the maintenance-free circuit-breakers and the modular design enable continuous operation without expensive shutdown times. In case of an unlikely event of an internal arc, the optional available arc quenching device SIQuench reduces the system repair time from days and weeks to hours and minutes. • Use of maintenance-free Siemens 3AE vacuum circuit-breakers or 3TM...
