Medium-voltage switchgear

Power Xpert UX

Eaton’s Power Xpert UX IEC medium-voltage switchgear system can be used for a wide range of power distribution and motor control applications at rated voltages up to 24 kV. The system is available in single and double busbar (duplex) configurations. The Power Xpert UX withdrawable primary switchgear has been designed with safety in mind and offers a reliable and flexible solution with a compact footprint. The compact design of Power Xpert UX relies on two flagship technologies from Eaton's portfolio, namely cast-resin insulation and vacuum interrupters.

Safe and reliable primary withdrawable switchgear up to 24 kV

The Power Xpert UX design is focused on single pole insulation and isolation of current paths. These arc free zones reduce the potential of internal faults greatly. In case of an internal fault the optional integrated arc absorber technology can exhaust an internal arc inside a switchroom without bringing harm to the staff or equipment. During the operation the racking is behind closed doors to ensure full internal arc containment with an option for full remote operation of the switchgear without entering the switchroom.

SF₆-free switchgear

Power Xpert UX uses vacuum technology instead of SF₆. This eliminates the risk of leakage and minimizes maintenance costs as well as expensive end-of-life disposal procedures - all materials being re-usable or recycled. Eaton campaigns for SF₆-free switchgear to protect our environment.
