Switchgear engineered for the AI era

As compute density climbs and campuses scale faster than ever, the equipment feeding your distribution has to keep pace. NX Switchgear is purpose-built low-voltage switchgear — UL 891 listed and assembled in the USA — that anchors the service entrance and main distribution of facilities that can't afford to wait or compromise on reliability.

From a single main-distribution lineup to a full network of feeders, NX Switchgear is the same forward-looking platform as the rest of the NextGen ecosystem: high-tech, configurable, and ready to deploy with confidence.

Key Advantages

Why specify NX Switchgear

▲

Built For What's Next

Designed around the load profiles, redundancy, and density of modern data centers and hyperscale — not yesterday's facilities.

⏱

Rapid Deployment

Standard configurations move fast, with build-to-spec lineups on a timeline that supports rapid expansion. Deploy with confidence.

✓

UL 891 Listed

Third-party listed low-voltage switchgear you can submit and inspect without surprises. A standard you can plan around.

⚙

Premium Components

Siemens-approved OEM build with quality breakers and bus — engineered for long service life under continuous load.

⚡

Scalable & Configurable

From 400A to 4000A, indoor or outdoor, single section to full lineup — configured to your one-line, not a fixed catalog.

⚑

Engineering Support

Real engineering partnership from one-line review through submittals, factory acceptance, and field start-up.

NX Switchgear outdoor NEMA 3R lineup
Indoor & Outdoor

NEMA-rated for any environment

Specify NX Switchgear as indoor UL Type 1 for clean electrical rooms, or as outdoor NEMA 3R construction for pad-mounted and yard installations where space inside the building is at a premium. Either way, you get the same listed assembly and the same dependable performance.

Outdoor lineups are engineered to keep the elements out while keeping maintenance access in — so you can place power generation and distribution where the campus actually needs it.

  • Indoor UL Type 1 enclosures
  • Outdoor NEMA 3R weather-resistant construction
  • Front-access and front/rear-access layouts to fit the room
  • Top and bottom cable/bus entry options
One Ecosystem

Switchgear, RPPs, and monitoring that work as a system

NX Switchgear is one piece of the NextGen equipment ecosystem. Specify it alongside the NX Series RPP and NX Intelligent BCMS for a coordinated, source-to-rack power chain — from a single manufacturer, on a single timeline.

PAIRS WITH
⚡

NX Series RPP

Feed your remote power panels directly from NX Switchgear. Models NX-225, NX-400, NX-600, 225A–600A at 480V max, up to 84 branch positions — power right at the rack rows.
PAIRS WITH
🔌

NX Intelligent BCMS

Add true-RMS branch-circuit monitoring at ±0.5% with local touchscreen and remote access — full visibility into current, voltage, energy, and power quality behind closed doors.
COMPLETE CHAIN
⚙

Source To Rack

Switchgear at the service entrance, RPPs at the rows, and intelligent monitoring throughout — coordinated bus, ratings, and submittals from one OEM.
