Two Products Offer
Design Flexibility
As a manufacturer of two
lines of loadcenters, Eaton
is in a unique position to
offer the broadest range of
interiors in the market. Each
line has its own unique
characteristics that appeal
to various segments of the
market. OEM interiors are
UL recognized components
and are listed in either of
the following UL files: E8741
or E52977.
The CH interiors feature
100% copper bus and use
the CH 3/4-inch (19.1 mm)
wide circuit breaker, which
minimizes panel space.
Recognized by contractors
for its sturdy design, the
CH interior will appeal to
those customers seeking
an industrial quality bolted
busbar and the space saving
of 3/4-inch (19.1 mm) per
bus stab. With a typical
12 circuit CH interior, this
space savings amounts
to an inch and a half savings
over its 1-inch (25.4 mm)
counterparts. The stab
rating of the CH interiors
is 140 A maximum meaning
that the handle rating of
breakers mounted across
from one another may not
exceed 140 A.
The BR interiors are
manufactured of formed,
plated aluminum or copper,
and use Eaton’s Type BR
1-inch (25.4 mm) wide circuit
breaker. This design affords
customers the most circuit
flexibility as many of these
interiors allow the installation
of standard single- and
two-pole breakers as well as
duplex (two poles in a 1-inch
(25.4 mm) space) or quadplex
(four poles in a 2-inch
(50.8 mm) space) breakers.
The stab rating of the BR
interiors is 200 A maximum,
meaning that the handle
rating of the breakers that
are mounted across from
one another may not
exceed 200 A.
The interiors are designed
for either horizontal (single-
row breaker mounting), or
vertical (double-row breaker
mounting). To comply with
National Electrical Code
(NEC) requirements, if
mounted horizontally, when
the breaker is ON, the handle
should be in the UP position.
When mounted vertically, the
handle toggles from left to
right, so this is not a concern.
