Switched ZeroU PDU for 208V Racks

This APC Rack PDU 9000 is a switched power distribution unit built for 208V three-phase environments. It delivers up to 8.6kW through a NEMA L21-30P input plug. The ZeroU form factor mounts vertically inside a rack, leaving horizontal U-space free for servers and networking gear.

Vertical 80.31-inch chassis with NEMA L21-30P input

The unit measures 80.31 by 6.5 by 4.88 inches, fitting standard deep racks without consuming rack units. A locking NEMA L21-30P cord secures the 30A three-phase feed, reducing accidental disconnects. Switched outlets allow remote on-off cycling and sequenced startup for connected equipment.

Verify 208V three-phase supply

Confirm the facility provides 208V three-phase power with a compatible 30A branch circuit and L21-30 receptacle. Ensure the rack depth accommodates the 80.31-inch height and that cable routing reaches the input location. This PDU does not suit single-phase or lower-voltage installations.

Questions about this item

What does the NEMA L21-30P input plug limit the PDU to?

The NEMA L21-30P plug connects to a 208 V three-phase supply rated at 30 A, giving a maximum capacity of 8.6 kW.

What clearance does the ZeroU chassis need to mount vertically?

The unit measures 80.31 inches long, 6.5 inches wide and 4.88 inches deep, so it fits in the zero-U channel of a standard rack.

How is the PDU commissioned on the network and what step is often missed?

Connect the management port, assign a static IP or enable DHCP, then register each outlet in the web interface — skipping outlet naming makes power cycling unreliable.
