Application Description
The basic purpose of a transformer
is voltage transformation as near as
practically possible to the load for
economy and distribution of power.
Typical loads for dry-type distribution
transformers include lighting, heating,
air conditioners, fans and machine
tools. Such loads are found in com-
mercial, institutional, industrial
and residential structures.
Features, Benefits
and Functions
UL
listed.
60 Hz operation.
Short-term overload capability
as required by ANSI.
Meet NEMA ST-20 sound levels.
Standards and Certifications
Industry Standards
All Cutler-Hammer
dry-type distribu-
tion and control transformers by Eaton
Corporation are built and tested in
accordance with applicable NEMA,
ANSI and IEEE Standards. All 600 volt
class transformers are UL listed unless
otherwise noted.
Seismically Qualified
Cutler-Hammer manufactured dry-type
distribution transformers are seismi-
cally qualified, and exceed require-
ments of the Uniform Building Code
(UBC), International Building Code
(IBC), and California Code Title 24.
Product Specifications
Frequency
Cutler-Hammer standard dry-type
distribution transformers are designed
for 60 Hertz operation. Transformers
required for other frequencies are
available and must be specifically
designed.
Overload Capability
Short-term overload is designed into
transformers as required by ANSI.
Dry-type distribution transformers
will deliver 200% nameplate load for
one-half hour; 150% load for one hour;
and 125% load for four hours without
being damaged provided that a con-
stant 50% load precedes and follows
the overload. See ANSI C57.96-01.250
for additional limitations.
Continuous overload capacity is not
deliberately designed into a trans-
former because the design objective is
to be within the allowed winding tem-
perature rise with nameplate loading.
Insulation System and Temperature Rise
Industry standards classify insulation
systems and rise as shown below:
Table 44-1. Insulation System Classification
The design life of transformers having
different insulation systems is the
same — the lower temperature systems
are designed for the same life as the
higher temperature systems.
Enclosures
Cutler-Hammer ventilated transform-
ers, Type DS-3, utilize a NEMA 2 rated
(drip-proof) enclosure as standard,
and are rated NEMA 3R with the addi-
tion of weathershields. Cutler-Hammer
encapsulated transformers, Type EP,
utilize a NEMA 3R rated enclosure
as standard.
Sound Levels
All Cutler-Hammer 600 volt class
general purpose dry-type distribution
transformers are designed to meet
NEMA ST-20 sound levels listed here.
These are the sound levels measured
in a soundproof environment. Actual
sound levels measured at an installa-
tion will likely be higher due to electri-
cal connections and environmental
conditions. Lower sound levels are
available and should be specified
when the transformer is going to
be installed in an area where sound
may be a concern.

General Purpose Transformers
Single-Phase Encapsulated (Type EP), Ventilated (Type DS-3), 60 Hz
Winding Terminations
Primary and secondary windings are
terminated in the wiring compartment.
Encapsulated units have copper leads
or stabs brought out for connections.
Ventilated transformers have leads
brought out to aluminum pads that
are pre-drilled to accept Cu/Al lugs.
Lugs are not supplied with these
transformers.
Eaton recommends
external cables be rated 90°C (sized
at 75°C ampacity) for encapsulated
designs and 75°C for ventilated
designs.
Series-Multiple Windings
Series-multiple windings consist of
two similar coils in each winding
which can be connected in series or
parallel (multiple). Transformers with
series-multiple windings are desig-
nated with an “X” or “/” between the
voltage ratings, such as voltages of
“120/240” or “240 X 480.” If the series-
multiple winding is designated by an
“X,” the winding can be connected
only for a series or parallel. With the
“/” designation, a mid-point also
becomes available in addition to the
series or parallel connection. As an
example, a 120 X 240 winding can be
connected for either 120 (parallel) or
240 (series), but a 120/240 winding can
be connected for 120 (parallel), or 240
(series), or 240 with a 120 mid-point.
The following pages provide listings for most
standard transformer ratings and styles.
For other ratings or styles not shown, or for
special enclosure types (including stainless
steel), refer to Eaton.

Application Description
Electrostatically shielded transformers
are used to protect sensitive electrical
equipment from undesirable high fre-
quency signals commonly generated
by lighting, switching surges, motors,
and SCRs feeding noise back into the
line. An electrostatic shield, consisting
of a single turn of aluminum foil placed
between the primary and secondary
winding, is used to provide from
30 to 70 dB attenuation of wide band
line-to-ground (common mode) noise.
Typical uses of shielded isolation
transformers include:
Suppression of transients and noise
which travels from its source to the
sensitive load equipment.
Suppression of noise and transients
at the point where the noise or
transients are originating, thus
preventing them from backfeeding
from the source to the feeders.
Transform one voltage level to
another.
Isolate one circuit from another.
Features, Benefits
and Functions
UL listed.
60 Hz operation standard,
50/60 Hz operation available.
Short-term overload capability
as required by ANSI.
Meet NEMA ST-20 sound levels.
Standards and Certifications
Industry Standards
All Cutler-Hammer dry-type distribution
and control transformers by Eaton
Corporation are built and tested in
accordance with applicable NEMA,
ANSI and IEEE Standards. All 600 volt
class transformers are UL listed unless
otherwise noted.
Seismically Qualified
Cutler-Hammer manufactured dry-type
distribution transformers are seismi-
cally qualified, and exceed require-
ments of the Uniform Building Code
(UBC), International Building Code (IBC)
and California Code Title 24.
Product Specifications
Frequency
Cutler-Hammer standard dry-type dis-
tribution transformers are designed
for 60 Hertz operation. Transformers
required for other frequencies are
available and must be specifically
designed.
Overload Capability
Short-term overload is designed into
transformers as required by ANSI.
Dry-type distribution transformers
will deliver 200% nameplate load for
one-half hour; 150% load for one hour;
and 125% load for four hours without
being damaged provided that a con-
stant 50% load precedes and follows
the overload. See ANSI C57.96-01.250
for additional limitations.
Continuous overload capacity is not
deliberately designed into a trans-
former because the design objective is
to be within the allowed winding tem-
perature rise with nameplate loading.
Insulation System and Temperature Rise
Industry standards classify insulation
systems and rise as shown below:
Table 44-7. Insulation System Classification
The design life of transformers having
different insulation systems is the
same — the lower temperature systems
are designed for the same life as the
higher temperature systems.
Enclosures
Cutler-Hammer ventilated
transformers, Types DS-3 and DT-3
utilize a NEMA 2 rated (drip-proof)
enclosure as standard, and are rated
NEMA 3R with the addition of
weathershields. Cutler-Hammer
encapsulated transformers, Types
EP and EPT, utilize a NEMA 3R rated
enclosure as standard.
The following pages provide listings for most
standard transformer ratings and styles.
For other ratings or styles not shown, or for
special enclosure types (including stainless
steel), refer to Eaton.

Electrostatically Shielded Transformers
Single- and Three-Phase, Types EP, 60 Hz
Sound Levels
All Eaton’s Cutler-Hammer 600 volt
class general purpose dry-type distri-
bution transformers are designed to
meet NEMA ST-20 sound levels listed
here. These are the sound levels mea-
sured in a soundproof environment.
Actual sound levels measured at an
installation will likely be higher due to
electrical connections and environ-
mental conditions. Lower sound levels
are available and should be specified
when the transformer is going to
be installed in an area where sound
may be a concern.
Table 44-8. Average Sound Levels
Currently being reviewed and revised by
NEMA.
Winding Terminations
Primary and secondary windings are
terminated in the wiring compartment.
Encapsulated units have copper leads or
stabs brought out for connections. Venti-
lated transformers have leads brought
out to aluminum pads that are pre-drilled
to accept Cu/Al lugs. Lugs are not sup-
plied with these transformers. Eaton rec-
ommends external cables be rated 90°C
(sized at 75°C ampacity) for encapsulated
designs and 75°C for ventilated designs.
Series-Multiple Windings
Series-multiple windings consist of
2 similar coils in each winding which
can be connected in series or parallel
(multiple). Transformers with series-
multiple windings are designated with
an “X” or “/” between the voltage
ratings, such as voltages of “120/240”
or “240 X 480.” If the series-multiple
winding is designated by an “X,” the
winding can be connected only for a
series or parallel. With the “/” designa-
tion, a mid-point also becomes avail-
able in addition to the series or parallel
connection. As an example, a 120 X 240
winding can be connected for either
120 (parallel) or 240 (series), but a
120/240 winding can be connected
for 120 (parallel), or 240 (series), or
240 with a 120 mid-point.

Open Type Core and Coil Assembly Transformers
Single- and Three-Phase
Single- and Three-Phase,
Types DS-3C, DT-3C, 60 Hz
Product Description
220°C insulation system, 150°C
rise standard; 115°C or 80°C
optional.
Aluminum windings
(copper optional).
Application Description
The basic purpose of a transformer
is voltage transformation as near as
practically possible to the load for
economy and distribution of power.
Typical loads for dry-type distribution
transformers include lighting, heating,
air conditioners, fans, and machine
tools. Such loads are found in
commercial, institutional, industrial,
and residential structures.
Open core and coil assemblies are
typically used by panel builders and
equipment OEM customers who
incorporate the entire transformer
into their structures. A versatile option
to purchasing a standard, enclosed
transformer and discarding the
unneeded enclosure parts.
Features, Benefits
and Functions
(UL recognized).
60 Hz operation standard,
50/60 Hz operation available.
Short-term overload capability as
required by ANSI.
Meet NEMA ST-20 sound levels.
Standards and Certifications
Industry Standards
All Cutler-Hammer dry-type distribu-
tion and control transformers by Eaton
Corporation are built and tested in
accordance with applicable NEMA,
ANSI, and IEEE Standards.
Seismically Qualified
All Cutler-Hammer manufactured
dry-type distribution transformers
are seismically qualified, and exceed
requirements of the Uniform Building
Code (UBC), International Building
Code and California Code Title 24.
Product Specifications
Frequency
Cutler-Hammer standard dry-type distri-
bution transformers are designed for 60
Hz operation. Transformers required for
other frequencies are available and
must be specifically designed.
Overload Capability
Short-term overload is designed into
transformers as required by ANSI.
Dry-type distribution transformers
will deliver 200% nameplate load for
one-half hour; 150% load for one-hour;
and 125% load for four-hours without
being damaged provided that a con-
stant 50% load precedes and follows
the overload. See ANSI C57.96-01.250
for additional limitations.
Continuous overload capacity is not
deliberately designed into a trans-
former because the design objective is
to be within the allowed winding tem-
perature rise with nameplate loading.
Insulation System and Temperature Rise
Industry standards classify insulation
systems and rise as shown below:
Table 44-13. Insulation System Classification
The design life of transformers having
different insulation systems is the
same — the lower temperature systems
are designed for the same life as the
higher temperature systems.
Sound Levels
All Cutler-Hammer 600 volt class general
purpose dry-type distribution transform-
ers are designed to meet NEMA ST-20
sound levels listed here. These are the
sound levels measured in a soundproof
environment. Actual sound levels mea-
sured at an installation will likely be higher
due to electrical connections and environ-
mental conditions. Lower sound levels are
available and should be specified when
the transformer is going to be installed in
an area where sound may be a concern.
Table 44-14. Average Sound Levels
Currently being reviewed and revised by
NEMA.
Winding Terminations
Lugs are not supplied with these trans-
formers. Eaton recommends external
cables be rated 90°C (sized at 75°C
ampacity) for encapsulated designs
and 75°C for ventilated designs.
Series-Multiple Windings
Series-multiple windings consist of 2
similar coils in each winding which can
be connected in series or parallel (multi-
ple). Transformers with series-multiple
windings are designated with an “X” or
“/” between the voltage ratings, such as
voltages of “120/240” or “240 X 480.” If
the series-multiple winding is desig-
nated by an “X,” the winding can be
connected only for a series or parallel.
With the “/” designation, a mid-point
also becomes available in addition to
the series or parallel connection. As an
example, a 120 X 240 winding can be
connected for either 120 (parallel) or 240
(series), but a 120/240 winding can be
connected for 120 (parallel), or 240
(series), or 240 with a 120 mid-point.

Application Description
A buck-boost transformer is used
to provide an economical method of
correcting a lower or higher voltage
rating more suitable for efficient oper-
ation of electrical equipment. Type EP
Buck-Boost transformers are small
kVA, single-phase transformers with
dual primary and dual secondary
windings and are usually connected as
autotransformers by utilizing one unit
for single-phase applications and
either two or three units banked for
three-phase operation. They are pri-
marily used for motor operation and
should not be used for motor control
circuits, to correct fluctuating line
voltage or to obtain a neutral on a
delta system. Buck-boost transformers
are ideally suited for use with low
voltage lighting systems, such as
outdoor lighting.
Features, Benefits
and Functions
UL listed.
60 Hz operation.
600 volt class insulation.

Enclosures
Cutler-Hammer encapsulated buck-
boost transformers utilize a NEMA 3R
rated enclosure.
Sound Levels
All Cutler-Hammer 600 volt class gen-
eral purpose dry-type distribution
transformers are designed to meet
NEMA ST-20 sound levels listed here.
These are the sound levels measured
in a soundproof environment. Actual
sound levels measured at an installa-
tion will likely be higher due to electri-
cal connections and environmental
conditions. Lower sound levels are
available and should be specified
when the transformer is going to be
installed in an area where sound may
be a concern.
Table 44-18. Average Sound Levels
Currently being reviewed and revised by
NEMA.
Winding Terminations
Primary and secondary windings are
terminated in the wiring compartment.
Encapsulated units have copper leads
or stabs brought out for connections.
Lugs are not supplied with these
transformers. Eaton recommends
external cables be rated 90°C (sized
at 75°C ampacity) for encapsulated
designs.

Buck-Boost and Low Voltage Lighting Transformers
Single- and Three-Phase
Series-Multiple Windings
Series-multiple windings consist of 2
similar coils in each winding which
can be connected in series or parallel
(multiple). Transformers with series-
multiple windings are designated with
an “X” or “/” between the voltage
ratings, such as voltages of “120/240”
or “240 X 480.” If the series-multiple
winding is designated by an “X,” the
winding can be connected only for a
series or parallel. With the “/” designa-
tion, a mid-point also becomes avail-
able in addition to the series or parallel
connection. As an example, a 120 X
240 winding can be connected for
either 120 (parallel) or 240 (series), but
a 120/240 winding can be connected
for 120 (parallel), or 240 (series),
or 240 with a 120 mid-point.
Note: When installation is to be made on a
grounded system, consideration must be
given to the resulting voltage. Thus, on a
208 grounded wye/120 system the voltage
can be boosted to 240 volts but the voltage
to ground will be 139 volts. If 240/120 volts
with a mid-point ground is needed, a stan-
dard two-winding transformer must be used.
The following formulas can be used to
calculate specific requirements.

For quick selection data, refer to the
tables on the following pages.
Selection Requirements
You should have the following
information before selecting a
buck-boost transformer.
Line Voltage
The voltage that you want to buck
(decrease) or boost (increase). This
can be found by measuring the supply
line voltage with a voltmeter.
Load Voltage
The voltage at which your equipment
is designed to operate. This is listed on
the nameplate of the load equipment.
Load Amperes or Load kVA
You do not need to know both — one
or the other is sufficient for selection
purposes. This information usually can
be found on the nameplate of the
equipment that you want to operate.
Frequency
The supply line frequency must be the
same as the frequency of the equip-
ment to be operated — Eaton’s Cutler-
Hammer Buck-Boost Transformers
operate at 60 Hz only.
Phase
The supply line should be the same as
the equipment to be operated — either
single or three-phase.
Transformer Interconnection
For three-phase applications, intercon-
nections of transformers should be
made in a junction box. Two or three
transformers may be used depending
on an open delta (2) or wye (3)
connection.
5-Step Selector
The tables which follow will simplify
the selection of the buck-boost trans-
formers. There are no calculations
needed; simply follow these 5 steps.
1. Refer to the table having the same
output voltage as the equipment
you want to operate. For example,
if you are installing a 240 volt 6 kVA
single-phase load use Selection
Table 44-23.
2. Select the available line voltage
across the top of the chart which
is closest to the actual supply volt-
age. Therefore, for example, if the
available line voltage is 213 volts,
use the 212 volt column.
3. Read down the column until you
reach an output kVA or amps rat-
ing equal to or greater than the
load requirements. Since 6 kVA, in
the example, is not listed, use the
next higher rating or 7.5 kVA.
4. Read across to the far left columns
for the catalog number and quan-
tity of transformers for your appli-
cation. In this case, you will need
one (1) catalog number
S10N06A01N.
5. Connect the buck-boost trans-
former(s) you have selected in
accordance with the connection
diagram specified at the bottom of
the available line voltage column.
In this example, Diagram “F”
would be used.
Note: For 1-phase connections and 3-phase
open delta connections, inputs and outputs
may be reversed. kVA capacity remains
constant.

Industrial Control Transformers
Type MTA
Type MTA
Type MTA Transformer
Product Description
Varnish impregnated core and
coil design.
Suitable for indoor applications.
Open core and coil design.
Application Description
Machine Tool and Industrial Control
Transformers provide stepped-down
voltages to machine tool control
devices enabling control circuits to
be isolated from all power and lighting
circuits. This allows the use of ground-
ed or ungrounded circuits that are
independent of the power or lighting
grounds; greater safety is afforded the
operator. The control transformer line
is particularly adaptable on applica-
tions where compact construction
is demanded.
Features, Benefits
and Functions
UL recognized component for units
rated 1000 VA and below.
CSA certified for units rated 1000 VA
and below.
55ºC rise, 105ºC insulation system.
60 Hz operation standard.
100% tested to verify product quality.
Performance equals or exceeds
requirements of ANSI/NEMA ST-1.
Regulation exceeds ANSI/NEMA
requirements for all ratings.
Each unit must pass rigid tests for
turns ratio, insulation, continuity,
and over potential.
50 – 5000 VA ratings.
Standards and Certifications
Industry Standards
All Cutler-Hammer dry-type distribu-
tion and control transformers by Eaton
Corporation are built and tested in
accordance with applicable NEMA,
ANSI and IEEE Standards.
Product Specifications
Frequency
Cutler-Hammer Type MTA control
transformers are designed for 60 Hertz
operation. Transformers required for
other frequencies are available and
must be specifically designed.
Insulation System and Temperature Rise
Industry standards classify insulation
systems and rise as shown below:
Table 44-34. Insulation System Classification
The design life of transformers having
different insulation systems is the
same — the lower temperature systems
are designed for the same life as the
higher temperature systems.
Series-Multiple Windings
Series-multiple windings consist of
2 similar coils in each winding which
can be connected in series or parallel
(multiple). Transformers with series-
multiple windings are designated with
an “X” or “/” between the voltage
ratings, such as voltages of “120/240”
or “240 X 480.” If the series-multiple
winding is designated by an “X,” the
winding can be connected only for a
series or parallel. With the “/” designa-
tion, a mid-point also becomes avail-
able in addition to the series or parallel
connection. As an example, a 120 X
240 winding can be connected for
either 120 (parallel) or 240 (series), but
a 120/240 winding can be connected
for 120 (parallel), or 240 (series), or 240
with a 120 mid-point.
The following pages provide listings for most
standard transformer ratings and styles.

Overcurrent Protection Tables
Overcurrent protection on both the primary and secondary sides of transformers are specified in UL 508 and the National
Electrical Code. The maximum acceptable ratings are shown below. Due to high inrush currents present when a transformer
is initially energized, it is recommended that the primary fuse be time delay to prevent nuisance trips during startup.
Table 44-35. Maximum Acceptable Rating of Primary Overcurrent Protection
Note: If the rated primary current is less than 2 amperes, the maximum rating of the overcurrent device is 300% for power circuits, shown
above, or 500% for control circuits, shown above (in brackets). If the rated primary current is 2 amperes or more, the maximum rating of the
overcurrent device is 250%. All figures assume secondary overcurrent protection per NEC/UL.
References: NEC 430-72 (c) exception 2, 450-3 (b) 1 & 2, UL 508 32.7, UL 845 11.16 and 11.17.
Table 44-36. Maximum Acceptable Rating of Secondary Overcurrent Protection
Note: If the rated secondary current is less than 9 amperes, the maximum rating of the overcurrent device is 167%; 9 amperes or more, the maximum
rating of the overcurrent device is 125%. If 125% does not correspond to a standard fuse rating, the next highest standard rating may be used.
References: NEC 430-72 (c) exception 2, 450-3 (b) 1 & 2, UL 508 32.7, UL 845 11.16 and 11.17.

Industrial Control Transformers
Type MTC
Type MTC
Type MTC Transformers
Product Description
Varnish impregnated core and
coil design.
Suitable for indoor applications.
Application Description
Transformers provide stepped down
voltages to machine tool control
devices enabling control circuits to be
isolated from all power and lighting
circuits. This allows the use of
grounded or ungrounded circuits that
are independent of the power or light-
ing grounds; greater safety is afforded
the operator. The control transformer
line is particularly adaptable on appli-
cations where compact construction
is demanded. The MTC line is similar
to the MTA line except it provides
increased regulation.
Features, Benefits
and Functions
Designed specifically for loads
requiring extremely good regulation
— 10% – 200% better regulation
than Type MTA.
UL recognized component for units
rated 1000 VA and below.
CSA certified for units rated 1000 VA
and below.
50/60 Hz operation standard.
100% tested to verify product quality.
Each unit must pass rigid tests for
turns ratio, insulation, continuity,
and over potential.
Performance equals or exceeds
requirements of ANSI/NEMA ST-1.
Regulation exceeds ANSI/NEMA
requirements for all ratings.
505000 VA ratings.
55ºC rise, 105ºC insulation system.
Standards and Certifications
Industry Standards
All Cutler-Hammer dry-type distribu-
tion and control transformers by Eaton
Corporation are built and tested in
accordance with applicable NEMA,
ANSI and IEEE Standards.
Product Specifications
Frequency
Cutler-Hammer standard dry-type dis-
tribution transformers are designed
for 60 Hz operation. Transformers
required for other frequencies are
available and must be specifically
designed.
Insulation System and Temperature Rise
Industry standards classify insulation
systems and rise as shown below:
Table 44-44. Insulation System Classification
The design life of transformers having
different insulation systems is the
same — the lower temperature systems
are designed for the same life as the
higher temperature systems.
Series-Multiple Windings
Series-multiple windings consist of 2
similar coils in each winding which
can be connected in series or parallel
(multiple). Transformers with series-
multiple windings are designated with
an “X” or “/” between the voltage
ratings, such as voltages of “120/240”
or “240 X 480.” If the series-multiple
winding is designated by an “X,” the
winding can be connected only for a
series or parallel. With the “/” designa-
tion, a mid-point also becomes avail-
able in addition to the series or parallel
connection. As an example, a 120 X
240 winding can be connected for
either 120 (parallel) or 240 (series), but
a 120/240 winding can be connected
for 120 (parallel), or 240 (series), or 240
with a 120 mid-point.
The following pages provide listings for most
standard transformer ratings and styles.

same — the lower temperature systems
are designed for the same life as the
higher temperature systems.
Series-Multiple Windings
Series-multiple windings consist of
2 similar coils in each winding which
can be connected in series or parallel
(multiple). Transformers with series-
multiple windings are designated with
an “X” or “/” between the voltage
ratings, such as voltages of “120/240”
or “240 X 480.” If the series-multiple
winding is designated by an “X,” the
winding can be connected only for a
series or parallel. With the “/” designa-
tion, a mid-point also becomes avail-
able in addition to the series or parallel
connection. As an example, a 120 X
240 winding can be connected for
either 120 (parallel) or 240 (series), but
a 120/240 winding can be connected
for 120 (parallel), or 240 (series),
or 240 with a 120 mid-point.

Industrial Control Transformers
Type MTK
Type MTK
Type MTK Transformers
Product Description
Epoxy resin-impregnated coil.
Economical solution for high
inrush applications.
Application Description
Transformers provide stepped down
voltages to machine tool control
devices enabling control circuits to be
isolated from all power and lighting
circuits. This allows the use of
grounded or ungrounded circuits that
are independent of the power or light-
ing grounds; greater safety is afforded
the operator. The control transformer
line is particularly adaptable on appli-
cations where compact construction
is demanded.
Features, Benefits
and Functions
UL listed.
CSA certified.
Epoxy resin impregnated coil design.
Copper magnet wire for high
quality, efficient operation.
50/60 Hz operation.
115°C rise, 180ºC insulation system.
Performance meets/exceeds
requirements of ANSI/NEMA ST-1.
Regulation exceeds ANSI/NEMA
requirements for all ratings.
500 – 5000 VA ratings.
Standards and Certifications
Industry Standards
All Cutler-Hammer dry-type distribution
and control transformers by Eaton
Corporation are built and tested in
accordance with applicable NEMA,
ANSI, and IEEE Standards. All 600 volt
class transformers are UL listed unless
otherwise noted.
Product Specifications
Insulation System and Temperature Rise
Industry standards classify insulation
systems and rise as shown below:
Table 44-57. Insulation System Classification
The design life of transformers having
different insulation systems is the
same — the lower temperature systems
are designed for the same life as the
higher temperature systems.
Series-Multiple Windings
Series-multiple windings consist of 2
similar coils in each winding which
can be connected in series or parallel
(multiple). Transformers with series-
multiple windings are designated with
an “X” or “/” between the voltage
ratings, such as voltages of “120/240”
or “240 X 480.” If the series-multiple
winding is designated by an “X,” the
winding can be connected only for a
series or parallel. With the “/” designa-
tion, a mid-point also becomes avail-
able in addition to the series or parallel
connection. As an example, a 120 X
240 winding can be connected for
either 120 (parallel) or 240 (series), but
a 120/240 winding can be connected
for 120 (parallel), or 240 (series), or 240
with a 120 mid-point.
The following pages provide listings for most
standard transformer ratings and styles.
For other ratings or styles not shown, refer

Industrial Control Transformers
CE Marked
CE Marked
Terminal Type A
Application Description
Transformers provide stepped down
voltages to machine tool control devices
enabling control circuits to be isolated
from all power and lighting circuits.
This allows the use of grounded or
ungrounded circuits that are indepen-
dent of the power or lighting grounds;
greater safety is afforded the operator.
The control transformer line is particu-
larly adaptable on applications where
compact construction is demanded.

Product Specifications
Overload Capability
Short-term overload is designed into
transformers as required by ANSI.
Basically, dry-type distribution trans-
formers will deliver 200% nameplate
load for one-half hour; 150% load for
one-hour; and 125% load for four-hours
without being damaged provided that
a constant 50% load precedes and
follows the overload. See ANSI
C57.96-01.250 for additional limitations.
Continuous overload capacity is not
deliberately designed into a trans-
former because the design objective is
to be within the allowed winding tem-
perature rise with nameplate loading.
Insulation System and Temperature Rise
Industry standards classify insulation
systems and rise as shown below:
Table 44-62. Insulation System Classification
The design life of transformers having
different insulation systems is the
same — the lower temperature systems
are designed for the same life as the
higher temperature systems.
Series-Multiple Windings
Series-multiple windings consist of
2 similar coils in each winding which
can be connected in series or parallel
(multiple). Transformers with series-
multiple windings are designated with
an “X” or “/” between the voltage
ratings, such as voltages of “120/240”
or “240 X 480.” If the series-multiple
winding is designated by an “X,” the
winding can be connected only for a
series or parallel. With the “/” designa-
tion, a mid-point also becomes avail-
able in addition to the series or parallel
connection. As an example, a 120 X
240 winding can be connected for
either 120 (parallel) or 240 (series), but
a 120/240 winding can be connected
for 120 (parallel), or 240 (series), or 240
with a 120 mid-point.

Industrial Control Transformers
Type AP
Type AP
Type AP Transformer
Product Description
Sand and Resin encapsulated
designs.
Application Description
Transformers provide stepped down
voltages to machine tool control
devices enabling control circuits to be
isolated from all power and lighting
circuits. This allows the use of
grounded or ungrounded circuits that
are independent of the power or light-
ing grounds; greater safety is afforded
the operator. The control transformer
line is particularly adaptable on appli-
cations where compact construction
is demanded.
Features, Benefits
and Functions
UL recognized.
Resin encapsulated.
60 Hz operation.
115°C winding rise.
Convenient screw-type terminal
board.
Bottom or side/wall mounting
designs.
Performance meets/exceeds
requirements of ANSI/NEMA ST-1.
Regulation exceeds ANSI/NEMA
requirements for all ratings.
Standards and Certifications
Industry Standards
All Cutler-Hammer dry-type distribution
and control transformers by Eaton
Corporation are built and tested in
accordance with applicable NEMA,
ANSI and IEEE Standards.
Product Specifications
Overload Capability
Short-term overload is designed into
transformers as required by ANSI.
dry-type distribution transformers
will deliver 200% nameplate load for
one-half hour; 150% load for one-hour;
and 125% load for four-hours without
being damaged provided that a con-
stant 50% load precedes and follows
the overload. See ANSI C57.96-01.250
for additional limitations.
Continuous overload capacity is not
deliberately designed into a trans-
former because the design objective is
to be within the allowed winding tem-
perature rise with nameplate loading.
Insulation System and Temperature Rise
Industry standards classify insulation
systems and rise as shown below:
Table 44-69. Insulation System Classification
The design life of transformers having
different insulation systems is the
same — the lower temperature systems
are designed for the same life as the
higher temperature systems.
Sound Levels
All Cutler-Hammer 600 volt class gen-
eral purpose dry-type distribution
transformers are designed to meet
NEMA ST-20 levels.
Winding Terminations
Eaton recommends external cables be
rated 90ºC (sized at 75°C ampacity) for
encapsulated designs.
Series-Multiple Windings
Series-multiple windings consist of
2 similar coils in each winding which
can be connected in series or parallel
(multiple). Transformers with series-
multiple windings are designated with
an “X” or “/” between the voltage
ratings, such as voltages of “120/240”
or “240 X 480.” If the series-multiple
winding is designated by an “X,” the
winding can be connected only for a
series or parallel. With the “/” designa-
tion, a mid-point also becomes avail-
able in addition to the series or parallel
connection. As an example, a 120 X
240 winding can be connected for
either 120 (parallel) or 240 (series), but
a 120/240 winding can be connected
for 120 (parallel), or 240 (series), or 240
with a 120 mid-point.

Single-Phase Transformers
How to Select Single-Phase Units
1. Determine the primary (source)
voltage — the voltage presently
available.
2. Determine the secondary (load)
voltage — the voltage needed at
the load.
3. Determine the kVA load:
— If the load is defined in kVA, a
transformer can be selected from
the tabulated data.
— If the load rating is given in
amperes, determine the load kVA
from the below chart. To determine
kVA when volts and amperes are
known, use the formula:
kVA = Volts x Amperes
1000
— If the load is an ac motor, deter-
mine the minimum transformer
kVA from the chart at the right.
— Select a transformer rating
equal to or greater than the
load kVA.
4. Define tap arrangements needed.
5. Define temperature rise.
Using the above procedure, select
the transformer from the listings in
this catalog.
Table 44-71. Single-Phase ac Motors
If motors are started more than once per hour, increase minimum transformer kVA by 20%.
Note: When motor service factor is greater than 1, increase full load amperes proportionally.
Example: If service factor is 1.15, increase above ampere values by 15%.

Product Description
Eaton’s PSS Series of power supplies is
designed to work in a variety of appli-
cations, including the power supply to
the IT. line of power control products.
They also work in most control applica-
tions that require 24V DC. All of the
PSS power supplies are designed to
provide the highest “outrush” current
in the industry for units of their size.
It is also the only line to provide 110 –
480V AC input voltage down to the
smallest current units.
Application Description
The PSS line of power supplies is
specifically designed to work with the
S801, S811, MV811 and IT. electro-
mechanical devices. They can also
serve in a variety of other applications,
including support of sensors, operator
interfaces, PLCs, communication net-
works, heaters and lights and in many
other industrial applications where
24V DC power supplies are required.
With the widest operating temperature
range in the industry, rugged design
and a long list of advanced features,
they can be applied in a very wide range
of applications.
The higher input voltage ranges are
designed to allow users to eliminate
the need for a control power trans-
former in the enclosure or cabinet,
thus saving space, wiring and money.
Features
Wide range voltage input
(110 – 480V AC operating).
High current outrush capability
in all units.
Semiconductor F47 approved.
Long ride-through capability
