Loadcenters and Circuit Breakers
Type CH Loadcenters and Circuit Breakers
Standards and Certifications
UL
®
Listings
All Eaton Type CH loadcenters
are listed under UL File E8741.
Neutral and Ground Terminals
The standard terminals on
grounds and neutrals are rated
to accept (3)—#14–#10 Cu/Al
or (1)—#14–4 wires. For larger
cables, add-on neutral lugs
may be ordered from the
Accessories.
Note: NEC
®
allows only one
current carrying conductor
per hole on neutrals unless
otherwise noted.
Bottom-Fed Loadcenters
When the power cable is
brought into the loadcenter
from below the panel; then
the main lug panels, and
single-phase, 225 A and
below, loadcenters can be
rotated 180 degrees to allow
straight-in wiring of power
cables to the main terminals.
Because the CSR main circuit
breaker handle operates
horizontally, the orientation
of the main circuit breaker
handle is consistent with
the requirements of NEC
Article 240.81.
Gutter Splicing
Loadcenters are not UL listed
as wiring troughs. Therefore,
gutter splicing of riser cables
to tap off to the main device
is not permitted. Refer to
NEC Article 373.8.
Fire Rating
Due to the numerous
openings in both loadcenter
boxes and trims, they should
not be mounted in firewalls.
There is no approval method
for sealing the enclosures for
this application.
Date Code
The date of manufacture of
each loadcenter is printed on
the outside of the carton as
well as inside the loadcenter.
On the carton, the date code
is printed on the end carton
label. In the loadcenter, the
date code is located on the
small white label located on
the right side wall (with the
main device on top).
The date code is in the
following format: F # # # &.
The “F” is the numeric code
for the Lincoln, IL plant,
and the three numbers
are the year and week of
manufacture, e.g., 023. The
“&” sign at the end signifies
the decade of the 2000s.
The “!” at the end signifies
the decade of the 2010s.
Therefore, the date code
F023& would indicate
that the product was
manufactured in the 23rd
week of 2000. The 1980s
are represented by a
“+” sign and the 1990s
are represented by a “=”
at the end of the code.
Plug-On Type CH Breakers
Quick-make, quick-break
switch mechanism combined
with inverse time element
tripping operation and trip-
free handle design. Type CH
circuit breakers trip to the
OFF position eliminating
nuisance callbacks. The
thermal-magnetic trip curve
avoids nuisance tripping on
mild overloads while reacting
almost instantaneously
to severe short-circuit
conditions. CHF breakers
include a ‘trip flag’ to
differentiate between a
tripped breaker and one that
has been turned off.
Multipole breakers have
internal common trip
connection to operate all
poles simultaneously.
Handles are marked with
ON-OFF indication and
ampere rating of the breaker.
Type CH breakers meet
UL Standard 489, NEMA
standards, and Federal Spec
Classification W-C 375 b/Gen.
They are UL listed under File
Number E11713, E8741,
E3624 and E51287: and
CSA
®
certified file number
LR87196, except Type
CHT breakers.
Type CH Circuit Breaker Ratings
Single- and double-pole CH
breakers rated 15 and 20 A
have low instantaneous
magnetic trip levels. The 15
and 20 A breakers with “HM”
suffix have high magnetic trip
settings recommended for
circuits with inherently high
inrush currents. All Type CH
breakers are marked for
heating, air conditioning
and refrigeration (HACR)
equipment application.
Single-pole 15–20 A breakers
are also suitable for switching
duty (SWD). Shunt trip coils
operate on 120 Vac and
require one additional pole
space per breaker.
