Options
The following options are available to enhance the performance of your system.
Contact an Eaton sales representative for information about any of these available
options.
1.2.1
Distribution Panels
Optional output 225A distribution panels distribute the output power from the AC
source to the load. The PDU contains up to two 42−circuit breaker panels
(Cutler-Hammer bolt-on type BAB or QBHW, or plug-on type HQP or QPHW) that can
be configured to meet facility needs. The distribution panels are behind the hinged
doors on the front of the PDU.
1.2.2
Subfeed Breakers
Optional output subfeed breakers distribute the output power from the AC source to
larger loads or remote power panels. The subfeed breakers are enclosed behind the
hinged doors on the front of the PDU. The PDU can contain up to eight 225A F"
frame subfeed breakers.
