Three-phase UPS buyer's hub
Don't shop models. Choose a family.
Every three-phase UPS decision is really a family decision — the range sets the scaling model, battery strategy, footprint and service path; the SKU just sets the kVA. This hub compares every family we stock across Eaton, APC/Schneider, Vertiv and XPC, each with its own deep-dive page: stocked models, runtime expansion, bypass options and a configured turnkey quote.

Eaton three-phase families
Eaton 9355 · 10–40 kVA
The tower workhorse with a massive installed base — replacements, bypass panels and battery strings all still in active demand.
9355 family hub →Eaton 93PM · 50–200 kW
Hot-swap power modules in a frame: capacity and N+1 grow module by module. Buy the frame half-full on purpose.
93PM family hub →Eaton 93E · 15–500 kVA
Straightforward double-conversion kVA without the modular premium — 40 kVA towers and the matching battery cabinet in stock.
93E family hub →Eaton BladeUPS · 12–60 kW
12 kW modules that stack to 60 kW N+1 inside the rack row — power protection as rack equipment, not furniture.
BladeUPS family hub →APC / Schneider Electric three-phase families
Easy UPS 3S · 10–40 kVA
Schneider's lowest cost per three-phase kVA — with a parallel-bypass trick that buys N+1 for far less than a premium platform.
Easy UPS 3S range hub →Galaxy VS · 10–100 kVA
The modern mid-range default: compact, efficient, smart modular batteries — every rating from 10 to 100 kVA on the shelf.
Galaxy VS family hub →MGE Galaxy 3500 · 10–30 kVA
Rugged towers with published runtime per battery configuration — nine stocked configs, runtimes on the hub page.
Galaxy 3500 family hub →Symmetra PX · 10–250 kW
The data-centre modular veteran — frames, battery units and refurbished power modules that keep an enormous installed base alive.
Symmetra PX family hub →Galaxy VM · 160–225 kVA
Building-scale protection in one frame, with modular VRLA battery strings — logistics and commissioning handled turnkey.
Galaxy VM family hub →Galaxy VX · 500–1500 kVA
Seventeen stocked configurations to 1.5 MVA — scalable and N+1 frames that turn the ten-year capacity plan into a configuration choice.
Galaxy VX family hub →Smart-UPS VT · 10–30 kVA
The like-for-like continuity path for the thousands of VT rooms already wired and certified — batteries and replacements stocked.
Smart-UPS VT family hub →Vertiv three-phase families
Liebert APS · 5–20 kVA N+1
FlexPower assemblies slide into the frame: capacity, N+1 and runtime all grow without replacing the unit.
Liebert APS family hub →Liebert ITA2 · 8–15 kVA
Rack/tower convertible three-phase — including a lithium-ion model and Li-Ion battery cabinets, rare in this class.
Liebert ITA2 family hub →Xtreme Power Conversion — the independent channel
XPC's M90 and X90 modular platforms deliver frame-and-module architecture (hot-swap power modules, scalable battery cabinets from 4 to 36 modules) at independent-channel value — the alternative when OEM procurement chains slow a project down. They're covered in depth in the modular UPS guide with 103 stocked components in the modular collection.

Common questions
Which three-phase UPS family is best?
The honest answer: the one whose scaling model matches your load's future. Fixed families (93E, Easy UPS 3S, Galaxy 3500) win on price for stable loads; modular families (93PM, Symmetra PX, Liebert APS, BladeUPS, XPC M90) win when growth or N+1 is coming; rack families (ITA2, BladeUPS) win when floor space is the constraint. The selector table above maps situations to families.
What does a three-phase UPS cost?
Configured systems are quoted, not carted: the UPS is often only half the number — batteries, bypass, freight class and installation scope set the rest. Send the requirement and you get a firm itemized quote with real availability per option.
Do I need N+1 redundancy?
If a UPS failure would stop revenue or safety-critical operations, yes — and on modular families it costs one extra module rather than a second UPS. If the load tolerates a maintenance window, N is fine and the budget goes to batteries instead.
Can you handle the whole project?
That's the model: supply, freight and rigging, electrical installation through licensed electricians, battery configuration, commissioning, and preventive maintenance afterward — one quote, one accountable team. We do the hard work.
What happens to the UPS being replaced?
We buy back working enterprise units (trade-in credit stacks with your replacement quote) and recycle batteries properly — decommissioning is quoted inside the same project.
All product and company names are trademarks of their respective holders. UPS Plus Battery is an independent supplier and is not affiliated with, endorsed by, or sponsored by the manufacturers listed.
Equipment list or panel readings + target runtime — we come back with a shortlist across families and a configured turnkey quote for each.
