DWARNING
DO NOT ATTEMPT TO INSTALL, TEST, OR PERFORM MAINTENANCE ON
EQUIPMENT WHILE IT IS ENERGIZED. DEATH OR SEVERE INJURY AND/
OR SUBSTANTIAL PROPERTY DAMAGE CAN RESULT FROM CONTACT
WITH ENERGIZED EQUIPMENT. BEFORE INSPECTING THE CIRCUIT
BREAKER IN AN ELECTRICAL SYSTEM, MAKE SURE THE CIRCUIT BREAKER
IS SWITCHED TO THE OFF POSITION AND THAT THERE IS NO VOLTAGE
PRESENT WHERE WORK IS TO BE PERFORMED. ALWAYS FOLLOW
GENERALLY ACCEPTED SAFETY PROCEDURES.
EATON IS NOT LIABLE FOR THE MISAPPLICATON OR MISINSTALLATION
OF ITS PRODUCTS.
The user is cautioned to observe all recommendations, warnings
and cautions relating to the safety of personnel and equipment, as
well as all general and local health and safety laws, codes and procedures.
The recommendations and information contained herein are based
on Eaton experience and judgement, but should not be considered
to be all-inclusive or covering every application or circumstance
which may arise. If any questions arise, contact Eaton for further
information or instructions.
1. Introduction
The F-Frame electronic Circuit Breaker (Figure 1) is available in the
3-pole style with three rated currents (80A, 160A, 225A) and four
electronic tripping options. For single-phase ground fault applications, both the supply and return must be routed through the
Breaker. Throughout this document, the electronic circuit breaker
will be referred to as a breaker. The circuit breaker is equipped with
an electronic sensing and tripping mechanism which makes the
inverse time delay release independently of ambient temperature.
A thermal memory is incorporated which prevents power operation
immediately after an overload trip.
2. Installation
The installation procedure consists of inspecting and mounting the
breaker, connecting and torquing the line and load terminations, and
attaching terminal shield or barriers when supplied. To install the
breaker, perform the following steps.
NOTICE
THE BREAKERS ARE FACTORY SEALED. ACCESSORY INSTALLATION
SHOULD BE DONE BEFORE THE BREAKER IS MOUNTED AND CONNECTED.
Mounting hardware and unmounted terminations (where required)
are supplied in separate packages.
Make sure that the breaker is suitable for the installation by comparing nameplate data with system requirements. Inspect the breaker
for completeness and check for damage before mounting.
DWARNING
BEFORE MOUNTING THE BREAKER IN AN ELECTRICAL SYSTEM,
MAKE SURE THERE IS NO VOLTAGE PRESENT WHERE WORK IS TO BE
PERFORMED. THE VOLTAGES IN ENERGIZED EQUIPMENT CAN CAUSE
INJURY OR DEATH.
Depending on the equipment configuration, the breaker can be
mounted using different styles of hardware. The following steps
describe how to mount the breaker using standard hardware. When
special hardware is needed with the electrical operator, for example,
the instruction leaflet describing the accessory also describes the
special mounting arrangements.
NOTICE
BEFORE MOUNTING THE BREAKER, CHECK TO SEE IF THE TERMINATION
DEVICES SHOULD BE INSTALLED FIRST. SEE TERMINATION INSTRUCTIONS.
Figure 1. F-Frame 310 + Electronic Circuit Breaker.
The electronic options include with or without ground fault and
a linear of I2t response for the short delay time. The LS and LSG
(catalog suffixes 33 and 35) have an I2t response for the short delay
time function. The LSI and LSIG (catalog suffixes 32 and 36) have a
flat response for the short delay time function. The LSG and LSIG
include the ground fault function. The LSI and LSIG configurations
also have a zone interlock option which are specified with the 32ZG
and 36ZG catalog suffixes. These breakers are designed to comply
with Underwriters Laboratories, Inc. Standard UL-489 and Canadian
Standards Association CSA-22.2.
To mount the breaker, perform the following steps:
1. For individual mounting panels, make sure the mounting panel
is predrilled using bolt drilling plan (Figure 2). For panel board
mounting, only load end support mounting holes are required.
For deadfront cover application, make sure panel cover is cut out
to correct escutcheon dimensions (Figure 3).

2. If the breaker includes factory installed internal accessories,
make sure accessory wiring can be reached when the breaker is
mounted.
3. Position the breaker on the mounting surface.
4. Install mounting screws, washers and nuts. Tighten screws firmly, but do not exceed 28 pound-inches (3.16 N.m.)
If an optional terminal end cover is to be installed with the breaker
(usually line end only), it must be positioned before the cable is connected to terminals.

DCAUTION
WHEN ALUMINUM CONDUCTORS ARE USED, THE APPLICATION OF
A SUITABLE JOINT COMPOUND IS RECOMMENDED TO REDUCE THE
POSSIBILITY OF TERMINAL OVERHEATING. TERMINAL OVERHEATING CAN
CAUSE NUISANCE TRIPPING AND DAMAGE TO THE BREAKER.
After mounting the breaker, line and load terminals and accessory
leads should be connected (see accessory schematic diagram on
side of breaker).
NOTICE
IF TERMINAL SHIELD OR INTERPHASE BARRIERS ARE TO BE INSTALLED
ON THE BREAKER, INSTALL THEM AFTER THE TERMINALS ARE CONNECTED.
•
If required, install terminal shield on breaker cover with mounting
screws provided.
•
If required, install an interphase barrier by sliding barrier into dovetail grooves between terminals.
•
After the breaker is installed, check all mounting hardware and
terminal connecting hardware for correct torque loading. Torque
values for line/load terminals are provided in Tables 1, 2 and 3.
