AI racks are pushing data center power systems into unfamiliar territory, and Vertiv is responding with a new design built for the final step before electricity reaches the rack. Announced on November 13, 2026, the PowerStation 3100 RPP targets AI and high-performance computing racks exceeding 100 kW, bringing higher capacity and rack-level fault isolation into one platform.
The panel is available immediately in North America. It covers 600 A, 800 A, 1,000 A and 1,200 A configurations on the same hardware platform, giving operators four current ratings without creating four separate equipment standards.
One Platform for Racks Above 100 kW
The PowerStation 3100 RPP addresses the final distribution stage before electricity reaches the rack. That location matters because AI infrastructure combines large power demands with equipment designs that can change from one deployment to the next.
Four-wire delivery at 415 V or 480 V can increase available fault current, which raises the short-circuit protection required at rack level. Direct liquid cooling adds another challenge: a coolant leak may demand immediate power isolation for one rack without shutting down neighboring systems.
Traditional panelboard-based remote power panels were not designed for those combined demands, according to Vertiv. The company says the PowerStation 3100’s custom busbar and molded-case circuit breakers provide three to five times the capacity of traditional panelboard-based RPPs.
Vertiv’s product documentation specifies a 100%-rated main breaker with a 65 kA interrupting capacity and no full-load derating. The enclosure also provides space for as many as 22 three-pole branch breakers, creating room for multiple rack connections within the same assembly.
Higher short-circuit withstand and interrupting ratings are intended to reduce the need for separate fault-current mitigation equipment. That can simplify the electrical path between the facility’s power system and the high-density racks it supports.
Power Isolation That Targets One Rack
The most direct response to liquid-cooling risk sits inside each branch breaker. Every branch breaker incorporates a remote shunt trip, allowing a facility’s leak-detection system to disconnect only the affected rack when it detects a leak.
Adjacent racks and the wider pod can remain energized. That distinction gives operators a way to respond to a coolant leak without cutting power across a larger group of systems.
Because the accessory sits inside the breaker, it does not enlarge the enclosure. The result combines rack-level isolation with the same physical equipment footprint, a useful tradeoff when dense computing equipment already consumes valuable data center space.
The branch breakers also support changing rack demands through adjustable trip units. Operators can switch among 60 A, 100 A and 150 A ratings within the same branch-breaker frame, allowing one frame to serve different power requirements without a breaker replacement.
That flexibility extends standardization beyond the main input rating. A deployment can retain the same branch-breaker frame as rack power demands change, while operators manage a common equipment approach across current and evolving architectures.
Designed for Flexible Data Center Deployment
The PowerStation 3100 arrives as a complete, pre-certified assembly and supports both AC power distribution and DC rack architectures. That lets operators standardize across deployment types rather than create separate distribution approaches for each architecture.
The enclosure measures 90 by 38 by 16 inches and weighs 814 pounds across the range. Front-only service access eliminates the need for rear clearance, while top cable entry supports installations on either raised floors or slabs.
Units can be mounted side by side, back to back, against a wall or standalone. A common frame across the 600 A, 800 A, 1,000 A and 1,200 A ratings is intended to simplify procurement and spare-parts management as deployments expand.
The demand behind that flexibility is clear in the power figures associated with newer computing environments: some facilities reach 10 times the total facility power capacity, racks can require 12 to 28 times more power per rack, and heat generation can reach five times previous levels. Those pressures make distribution infrastructure a central part of AI deployment planning, not a hidden detail behind the rack.
“As new GPU generations drive higher rack power demands, customers need distribution infrastructure that supports both current deployments and evolving architectures,” said Kyle Keeper, senior vice president of Vertiv’s Power Business Unit.
The PowerStation 3100 RPP puts that idea into hardware that spans four current ratings, supports liquid-cooling fault response and fits multiple installation layouts. As AI racks continue to demand more electricity, the equipment feeding them will need to adapt without forcing every expansion into a new standard.
