Product Overview
Universal Molded Case
Circuit Breakers…When
Higher Interrupting Ratings
Are Not Required
Gi-, Fi, Ji-, Ki-, Li-Frames
15–800 Amperes
IEC 947-2 440 Vac
NEMA 480 Vac
Eaton’s universal molded
case circuit breakers, in
one-, two- and three-pole
configurations, are designed
to provide an economical
alternative for applications
that do not require the higher
interrupting ratings and
modular accessories provided
by Series G® breakers.
As with other members of
Eaton’s family of molded
case circuit breakers,
universal breakers provide
high quality, reliability,
unmatched performance,
and outstanding value.
For NEMA and IEC Standard
Voltage Systems
These breakers have been
designated universal because
they can be applied to both
NEMA® and IEC standard
voltage systems: 277/
480 Vac, 220/380 Vac and
240/415 Vac at 60 or 50 Hz.
Eaton’s universal breakers
are rated from 15–800
amperes and are available in
five frame sizes. Each frame
size has the same compact
outside dimensions as
Series C® breakers.
Additionally, universal
breakers are suitable for 50°C
applications and have been
rigorously tested to the
IEC 947-2 standard. They
are assembled in an ISO®
certified facility.
Trip Units and Terminals
External Accessories
Universal breakers are
provided with factory-sealed
thermal-magnetic trip units.
Universal breakers use the
same external accessories as
Series C breakers: handle
mechanisms, motor
operators, lock-off devices,
bus bar extensions and
multiple terminal
arrangements.
The Gi-Frame breaker (15–
125 amperes, UL listed up to
60A; 70–125A are IEC only)
includes line and load
terminals with breaker
mounting hardware. Frames
Fi (15–225 amperes),
Ji (250 amperes), Ki (300–
400 amperes) and Li (500–
630 amperes) include line
and load end caps with
termination hardware
installed. The Li-Frame (700–
800 amperes) is fitted with
both line and load bus bar
extensions that use standard
hardware. A full complement
of end cap kit terminals is
available to customize
universal breakers as
required.

End Cap Accessory Kit
End caps for line and load
conductor termination are
optional with each breaker.
End caps secure the
conductor with a ring-type
connector. The kit includes
one end cap, three cap
screws, three nuts and three

12.4
Typical Specifications for Universal Molded Case Circuit Breakers
Electrical circuits shall
be protected by molded
case circuit breakers as
manufactured by Eaton.
Each pole of the one-,
two- and three-pole circuit
breakers shall provide
complete circuit overcurrrent
protection by having inverse
time and instantaneous
tripping characteristics and,
where applicable, be current
limiting.
The circuit breakers shall be
operated by a toggle-type
handle and have a quickmake, quick-break, overcenter switching mechanism
that is mechanically trip-free
from the handle so that the
contacts cannot be closed
against short circuit currents.
Tripping due to overload or
short circuits shall be clearly
indicated by the position of
the handle. The ON and OFF
positions shall be clearly
marked on the cover of the
circuit breaker (F-Frame and
larger) along with the
international symbols I for ON
and O for OFF on the handle,
providing positive indication
of the circuit breaker contact
position. Additionally, a
color-coded indication of
the circuit breaker contact
position shall be provided for
the F-Frame and have red for
ON, green for OFF, and white
for TRIPPED. An easily
accessible Push-To-Trip
button for mechanically
exercising the trip unit shall
be provided on the cover of
each circuit breaker (F-Frame
and larger). All poles of a
multi-pole circuit breaker shall
be so constructed as to
ensure simultaneous open,
close and trip operations.
Molded case circuit breakers
shall be of the inverse time
and instantaneous trip type
as provided by thermalmagnetic trip elements.
Non-interchangeable trip
circuit breakers shall be
factory sealed to prevent
tampering. Ampere ratings
shall be clearly visible from
the front of the circuit
breaker. Contacts shall be
non-welding silver alloy.
Arc extinction shall be
accomplished by means of
DE-ION® arc extinguishers,
consisting of metal grids
mounted in an insulating
support.
Circuit breakers shall be
completely enclosed in
a high-strength glasspolyester case.
The minimum interrupting
ratings of the circuit breakers
shall be at least equal to the
available short circuit current
at the line terminals. The
circuit breakers can be
applied in series rated
applications and subject to
test data verification.
Circuit breakers in frame
sizes 100 amperes through
800 amperes shall be
equipped with thermalmagnetic trip units.
Circuit breakers in the
125 ampere frame size shall
be supplied in one-, twoand three-pole models, as
specified on the drawings.
Circuit breakers in ratings of
225 ampere frame size shall
be supplied in two- or threepoles as specified on the
drawings. The 250 amperes
through 800 amperes frame
sizes shall be supplied as
three-pole models only as
specified on the drawings.
Electrical operators for circuit
breakers of the 400 ampere
frame size and below shall be
of the solenoid type with
maximum five-cycle closing
characteristics. Electrical
operators for circuit breaker
frame sizes 630 amperes
through 800 amperes shall be
of the motor driven type. All
electrical operators shall be
cover mounted.
Circuit breakers shall be
provided with uniformly
designed nameplates to
clearly indicate the type,
rating, listing/recognition/
certification marks, accessory
details and other information
defined in IEC 947-2.
