Vertiv Liebert NXL: key facts

Sources, checked October 3, 2026: Vertiv, Liebert NXL 250-1100 kVA (discontinued product family); Vertiv Canada, Liebert Series 610 (discontinued, replaced by Liebert NXL).

Is the Vertiv Liebert NXL discontinued? What replaces it?

Yes. Vertiv lists the Liebert NXL as a discontinued product family. Its page names no single replacement; Vertiv's replacement for its other large legacy ranges (Liebert EXL and Liebert NX 225 to 600 kVA) is the Liebert EXL S1, 250 to 1,200 kW. The NXL itself replaced the older Liebert Series 600 and Series 610. See the Vertiv Liebert EXL S1 page.

Units already installed keep working after the manufacturer's cut-off; what changes is parts and factory support. We maintain discontinued units and plan the replacement when it makes sense. How to plan the replacement of a discontinued three-phase UPS.
