Vertiv PowerStation 3100 RPP: 600-1,200 A Panel for 100 kW+ AI Racks

The panel is built on a custom busbar with molded case circuit breakers (MCCBs), according to Vertiv's release, and the company says that gives three to five times the capacity of traditional panelboard-based RPPs. Data Centre Magazine, which covered the launch the same day, repeated the specifications and quoted Kyle Keeper, senior vice president of Vertiv's Power Business Unit. Vertiv gives no price, no named customer and no kW rating for the panel itself.

The consequence is in the last metres of the hall. An RPP is the final distribution stage before the rack in Vertiv's power path, so its ratings and protection decide how much current reaches each 100 kW-class rack and what happens to that rack when a coolant leak is detected. Vertiv says delivering 415 V or 480 V to racks over four-wire designs can raise available fault current, and so the short-circuit withstand rating the rack-level gear needs. Direct liquid cooling adds a second demand: cutting power to one rack without dropping its neighbours.

What each breaker does

Every branch circuit breaker carries an integrated remote shunt trip, which lets the facility's leak detection system open the circuit for a single rack, Vertiv said, without shutting down adjacent racks or the pod. The accessory sits inside the breaker and adds no footprint. A shunt trip is a remote switch-off signal; the release does not say how fast the breaker responds, or which leak sensors it has been tested with.

The breakers use adjustable trip units that switch between 60 A, 100 A and 150 A ratings within one frame, so operators can raise a rack's allowance without replacing the breaker. Vertiv also lists higher short-circuit withstand and interrupting ratings, integrated power metering, and breaker position and trip status reported for every circuit. The enclosure has front-only service access. The release says the design supports both fully AC distribution and DC rack architectures, but names no DC voltage.

How it fits with our earlier coverage

The panel is the power-side counterpart to the cooling work Vertiv has announced in recent weeks. Its SmartIT rack, as Voltgrid reported, bundles direct-to-chip cooling and DC power, while the RPP can be deployed standalone or with Vertiv SmartRun and OneCore, which the release describes as pre-configured power-and-thermal and factory-built data center systems. Vertiv's coolant care expansion with Dow and Solenis covers leak detection and fluid health on the cooling side; the RPP is where a leak signal can become a power cut.

Rack loads are the reason. KT Cloud told Yonhap that dense AI racks now draw 30 kW to 150 kW, and cited a possible 600 kW per rack in future, as we noted from its Seoul liquid cooling lab. The 800 V DC route, which Envision says is live at its Ulanqab campus, is a different distribution voltage; the release says this panel supports DC rack architectures but does not say whether it serves 800 V DC.

What is not confirmed yet

The release gives no kW rating per panel, no voltage or short-circuit current values behind its fault-current claims, no lead time, no price and no customer. Artiverse, which also covered the launch on Nov. 13, cites a 65 kA interrupting capacity from Vertiv's product documentation; we could not check that document, so we do not use the figure. The three-to-five-times capacity claim is Vertiv's comparison against panelboard RPPs, and the release does not give the baseline. The three reports we read repeat the company's figures; none reports independent testing. Availability is North America only for now.
