Power Xpert UX

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.

Air and cast-resin insulation combined with Eaton's world leading vacuum switching technology

Safe and reliable primary withdrawable switchgear up to 24 kV

The design of the Power Xpert UX switchgear is based on the single-pole insulation and isolation of current paths. These arc-free zones greatly reduce the potential risk of internal faults. In case of an internal fault, the optional integrated arc absorber technology will exhaust an internal arc inside a switchroom without harming the staff or damaging the equipment. During operation, the racking is located behind closed doors to ensure full internal arc containment, with the option to operate the switchgear remotely without entering the switchroom.

SF6-free switchgear

Power Xpert UX uses vacuum technology instead of SF6. This eliminates the risk of leakage and minimises 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.

Specifications

Technical data

Please note that the height (C) is based on the use of a 560 mm high arc channel and the venting of internal faults outside the switchroom. We also offer solutions for reduced ceiling heights and the venting of internal faults inside the switchroom. Contact us for more information.
