All-Copper Mini-Power Center

Product Focus

Three Individual
Components Combined Into
a Single Unit to Save Space
and Installation Costs

Introduction

Eaton’s all-copper Mini-Power
Center incorporates all of
the features and benefits
included in the industry-proven
aluminum model, plus the
additional features of a
copper-wound transformer
with a copper loadcenter
chassis that accepts bolt-on
feeder breakers.

Today’s electrical distribution
systems are required to
do more in less space,

while at the same time be
cost-effective. Eaton provides
a solution that meets both of
these requirements with the
Mini-Power Center.

The Mini-Power Center
combines three individual
components into a single
NEMA Type 3R enclosure;
a primary main breaker, an
encapsulated transformer, and
a secondary main breaker type
distribution loadcenter. All
interconnecting wiring is
completed at the factory.

The all-copper Mini-Power
Center features a copper­wound transformer along
with a copper loadcenter
chassis that accepts Eaton’s
Type BAB family of bolt-on
feeder breakers.

Applications

Mini-Power Centers are used
wherever there is a 480 or 600
volt distribution system and
there are loads requiring
120/240 V single-phase or
208Y/120 V three-phase.

•

Industrial plant
assembly lines.

•

Plant expansions.

•

Test equipment.

•

Compare the Installation Cost Savings — 31 Percent Less

Because we knew that putting three components in one enclo­sure dramatically cuts installation time, we asked an electrical
contractor to estimate the job two ways:

•

Using a separate breaker, transformer and loadcenter, including
the connecting cable and hardware.

•

Using a Mini-Power Center.
