General Information
Types QB, QMS, QL, and TransforMore™
600 Volts and Below
General Information

Temperature Class

The complete family of transformers from GE provide quiet,
reliable transformer operation.

Industry standards classify insulation systems in accordance with
the rating system shown below.

All of the dry-type transformers through 1,000 kVA are UL listed
under the requirements of Standard 5085 and 1561. In addition,
each transformer meets the requirements of NEMA ST-20, 1992.
Type IP, QB and QMS models are C-UL listed.
General-purpose transformers are rated 600 Volts and below for
supplying appliance, lighting, and power loads from electrical
distribution systems. Standard distribution voltages are 600, 480,
and 240 Volts; standard load voltages are 480, 240, 208, and 120
Volts. The transformer is used to obtain the load voltage from the
distribution voltage. Since no vaults are required for installation,
these transformers can be located right at the load to provide
the correct voltage for the application. This eliminates the need
for long, costly, low-voltage feeders.

All standard, general-purpose, GE transformers meet all applicable
NEMA, ANSI, UL, and IEEE standards.
The design life of transformers having different insulation systems
is the same, since the allowable temperature rise of an insulation
material system is predicated on a specified life for all insulation.
The lower temperature systems are designed for the same life as
higher temperature systems.
Sound Levels

Construction
Types QB and QMS
Core and coils are contained within a NEMA 3R nonventilated
weatherproof enclosure. Type QB and QMS units feature
encapsulated core and coils.
Type QL
Units are enclosed in a NEMA 2 drip-proof metal enclosure with
natural-draft ventilation. Core-and-coil assembly is mounted on
rubber isolation pads to reduce noise. Weathershield kits are
available for conversion to a NEMA 3R enclosure suitable for
outdoor service. NEMA 3R stainless steel (Type 316) enclosure is
available up to 150kVA. To specify a stainless steel enclosure,
substitute an “S” in the fifth character in the GE product number.
Example: 9T83B3874 changes to 9T83S3874. All QL model
product numbers begin with 9T6, 9T7, 9T8, or 9T9.
TransforMore™
Units utilize fan assisted cooling to achieve reduced size and
improved efficiency. These units incorporate an audible alarm
and shunt activated disconnect switch for improved safety.
Weathershields are available to convert to NEMA 3R enclosure
for outdoor service. All TransforMore™ model product numbers
begin with 9T4.

All general-purpose transformers are as quiet, or quieter than
required by NEMA ST-20. Average sound levels are warranted not
to exceed the values listed for each load rating shown in the
adjacent table. Sound characteristics vary between transformers
of identical voltage and kVA rating. The range of variation may be
4 to 8 decibels.
These values apply only to specified test conditions because the
characteristic of the installation can cause them to be higher
under operating conditions. Where acoustical noise is deemed to
be of unusual concern, proper steps should be taken during
installation to minimize audible noise transmission.
TransforMore™ sound levels are ≤67dB and meet specs in the table
below when the fans are off and the transformer is operating at less
than 50% rated load.

Voltage Tap Arrangement
Transformer taps compensate for high or low line voltages.
Standard NEMA, ANSI three-phase taps are two 5 percent taps
below normal on transformers smaller than 30 kVA. This arrangement provides a 10 percent range of tap voltage adjustment.
Most standard QL units rated 15 through 300 kVA have available
six universal voltage taps—four 2 1/2 percent below normal, and
two 2 1/2 percent above normal. This arrangement provides a 15
percent range of tap voltage adjustment.

Dry Type Transformers

Section 10

K-Factor
Aluminum
Three-Phase TP-1
Product Description
These type QL transformers have passed the UL K-factor testing
program. K-factor is a standardized way to indicate the ability of
a transformer to withstand harmonics. These units shall not
exceed rated winding temperature rise at full load and rated Kfactor. Neutrals are capable of handling 200% of rated secondary
phase current.
Full-width copper electrostatic shielding is standard on all GE
K-factor rated transformers. Effective coupling capacitance is
30 pf. Common mode noise attenuation averages 120 dB, and
transverse mode noise attenuation averages 30 dB.
Application
For commercial applications with significance nonlinear electronic loading, use K=4 for systems with 50% connected nonlinear
electronic loads; K=13 for systems with 100% connected nonlinear electronic loads.

Type QL, UL K-Factor Transformer

Higher K-factor rated units are available for unique applications.

Dry Type Transformers

Section 10

Low Noise
Aluminum
Three-Phase TP-1
Product Description
These low noise transformers are designed to operate at reduced
noise levels. The vibrations within the magnetic steel core were
greatly reduced, thus lowering the humming of the transformer
from 3 to 5 dB less than NEMA/ANSI standards. Available in
Aluminum or Copper windings, with either a 150°C, 115°C or
80°C rise.
Application
Type QL low noise transformers are ideal when quiet operation is
required such as near offices, in school buildings, or hospitals.
Although they are inherently quieter, installation can greatly
influence their noise level and therefore care should be taken in
following acoustical principles as well as proper installation
procedures. Closets and corners should be avoided as they act as
megaphones by seemingly increasing noise levels.

Dry Type Transformers
Servicenter Mini-Unit Substations
Integral Transformer and Distribution Center
Product Description

Application

This easily installed and serviceable unit incorporates a Type QMS
transformer (single-phase) or a Type QL transformer (threephase), a primary main circuit breaker, a secondary main circuit
breaker, and a load-center-design breaker panel. Since these
components don’t have to be installed and interconnected separately, the contractor or user can reduce installation time and
costs. Because of the single-unit concept, only one, handy
Servicenter needs to be mounted.

The single-phase Servicenter can be used wherever 480 Volt
power is available and 120 or 240 Volt branch circuits are
required. The three-phase Servicenter can be used wherever 240
Volt∅, 480 Volt∅ or 600 Volt∅ is available and 208 Volt Y/120
Volt circuits are required. The unit can be used in such applications as vending machine areas, construction laboratory test
areas, general construction sites where temporary or quickly
obtained power is required, or where future expansion of branch
circuits is planned.

Available in single-phase, 5 through 25 kVA, and in three-phase,
15 through 30 kVA, 600 Volt class ratings, the GE Servicenter is a
convenient, economical way to meet your industrial and temporary power requirements.
The Transformer—The Servicenter utilizes GE transformer design
which has twenty years of field-proven experience behind it and
a long track record for assuring consistent, reliable performance.
Type QMS transformers employ a 180°C UL Recognized insulation
system with a 115°C rise. Type QL transformers employ a 220°C
UL Recognized insulation system with a 150°C rise.
The Panel—The panel assembly includes the rugged GE
PowerMark Plus™ circuit breaker load center interior, E-frame primary breakers, and E-frame or Q Line secondary breakers. The
load center will accept one-, two-, or three-pole (three-phase)
common trip circuit breakers and ground fault breakers. All
Servicenters come equipped with the properly sized primary main
and secondary main circuit breakers installed and prewired.
Branch breakers are not included.

—Vending or concession areas
—Office buildings
—Assembly lines
—Mining applications
—Parking lots
—Light industrial areas

Dry Type Transformers
Totally Enclosed, Nonventilated
TENV
15-75kVA, Three-Phase, TP-1
Totally enclosed nonventilated (TENV) transformers are an
excellent choice for applications where dry-type transformer
benefits are desired but the standard enclosure openings are
unacceptable because of adverse atmospheric conditions. TENV
transformers are recommended where dust, dirt or lint may be
present or where transformers are subject to sprays or controlled
wash-down conditions. They are UL Listed through 75kVA for
indoor or protected outdoor applications.
Advantages
—Dry-type transformer is housed in an enclosed NEMA 3R
non-ventilated compartment
—Convenient wiring compartment is located beneath the
transformer and has removable front and rear covers
—Copper bus bars are located at the front of the wiring
compartment and are clearly labeled
—All electrical connections between the transformer and
bus bars are factory wired

—No-weld coil termination design – an industry first
—Comprehensive factory testing assures quality

TENV Transformer

Features
—Quiet design - unique core and coil design makes GE TENV
transformers among the quietest available
—Core and coil assembly mounted on rubber isolation pads to
reduce noise
—Bolted coil terminations are more reliable than welded
terminations, and they eliminate weld failures and problems
associated with welding and weld splatter
—100% factory tested for shorts and coil integrity, current and
loss, voltage, impedance and noise
—Qualified to the seismic requirements of IEEE-693-1997 and
IBC-2003
—Copper ground strap
—Copper or aluminum windings available
—Available in 150°C, 115°C, and 80°C rise models
—Indoor or outdoor use

Dry Type Transformers
Midtapped
Three-Phase TP-1
Product Description
GE Type QL midtapped transformer enables the user to transform
three-phase power from 480 Volts primary to 240 Volts secondary and have 120 Volt, reduced capacity tap (RCT) single-phase
capability as well. This is because a single-phase midtap is
brought out of one coil of the unit’s three-phase secondary winding. These transformers are UL listed, File E-79145.
Application
The Type QL midtapped design can be used wherever there is 480
Volt, three-phase supply available and the load is primarily 240
Volt three-phase with a nominal amount of 120 Volt, single-phase
power required. Normally, in this instance, a small single-phase
as well as a three-phase transformer would be required to
provide the necessary transformation.
Caution: When utilizing the 120 Volt midtap for single-phase
applications, the single-phase load should not exceed 5 percent
of the three-phase kVA rating. The three-phase kVA load must be
reduced by the same percentage as that added by the singlephase load. Additional loading beyond 5 percent may cause the
transformer to overheat and fail. If the single-phase load is in
excess of 5 percent, it is recommended that a separate singlephase unit be used to handle the load.

Dry Type Transformers
Drive Isolation
Aluminum
Three-Phase
Application
The use of SCR control circuitry with adjustable-speed drives has
resulted in a need for a line of isolation transformers specifically
designed to meet the demanding requirements of SCR drives.
Symmetrically placed taps and added coil bracing minimize
mechanical forces caused by the often severe SCR drive duty
cycles. These features also help protect the transformer from the
regenerative duty and more frequent short-circuits associated

with SCR drives. Isolation transformers also reduce line-pollution
feedback resulting from SCR firing circuits. The GE delta-wye
designs meet the NEC requirements for grounded secondary
neutrals that isolate primary distribution systems. kVA ratings of
the DIT line cover most dc motor requirements from 3 to 1000 hp.
Enclosed drive isolation transformers are UL listed.

Section 10

Buck-Boost
Encapsulated
Autotransformers
For Bucking and Boosting Voltage

Wiring Diagram: Single-Phase

Application
For General Lighting and Power Service
Autotransformers are more economical than isolation transformers designed to carry the same load. Within their voltage limitations, they will perform the same function as transformers with
the exception of insulating two circuits. You can use these autotransformers to obtain 120 Volts from a 240 Volt circuit, to derive
a neutral on a 240 Volt, two-wire circuit, or to balance a 120/240
Volt, three-wire circuit. They also may be used in banks on
polyphase circuits. See footnotes below.

Dry Type Transformers

Section 10

Buck-Boost
Encapsulated
For Bucking and Boosting Voltage
Product Description
Buck boost transformers are small, single-phase, dry type distribution transformers designed and shipped as insulating/isolating
transformers. They have a dual voltage primary and a dual voltage secondary. These transformers can be connected for a wide
range of voltage combinations. The most common use is to buck
(lower) or boost (raise) the supply voltage a small amount, usually 5 to 27%. Buck boost transformers comply with NEC Article
210-9, Exception 1, when field connected as an autotransformer.
GE bucking and boosting transformers provide an economical
and convenient means for bucking or boosting voltage, usually
no more than ±20% on single- and three-phase circuits. They are
compact, relatively light in weight, and can be easily installed for
indoor or outdoor service.
Buck-boost transformers are employed primarily for boosting
single-and three-phase circuits by connecting them as autotransformers. When connected as an autotransformer, only the
low-voltage, high-current capacity secondary windings are
required to carry the load. Because this load is only transformed
over a small change in voltage, the buck-boost transformer can
handle loads many times its nameplate kVA rating.

Indoor/Outdoor Type QB Transformer; Single-Phase

The transformers with series-multiple 12/24, 24/48, or 16/32 Volt
secondary windings are suitable for a wide variety of applications. Two or more units can be used in various combinations to
obtain many other special voltages. (For fluctuating voltage conditions, refer to Power Conditioning Equipment Products section
starting on page 10-36).

—Qualified to the seismic requirements of IEEE-693-1997 and
IBC-2003
—ABS (American Bureau of Shipping) Type Approved
Applications
—International voltage adaptation
—Commercial and industrial air conditioning
—Heating systems
—Induction motors
—Voltage line drop correction
—Landscape lighting
—Low-voltage lighting
—Marine and Offshore - ABS Classed Vessels
Efficient operation of electrical equipment requires that line voltage be at or near the nameplate rating of the equipment. In
order to match available line voltage (whether it be too high or
low) with equipment voltage, buck-boost transformers provide
the most convenient and least expensive method.
Do not use buck-boost transformers to solve a fluctuating voltage
problem. They should be used to compensate for high- or lowvoltage conditions only when the available line voltage is
reasonably constant.

NOTE: In addition to bucking or boosting low circuit voltages to related value, these transformers can be used as two winding transformers to supply the rated nameplate
low voltages, 12 to 48 Volts, two-wire or 12/24 to 24/48 Volts, three-wire. Also available in 50/60 Hz ratings.

Buck-Boost Selection Tables
Encapsulated
For Bucking and Boosting Voltage
5-Step Selection
The tables on these pages greatly facilitate buck-boost transformer selection. Simply follow these five easy 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 230 Volt single-phase air conditioner, use the
230 Volt table.
2. Different available “line voltages” are listed across the top of
each table. Select the line voltage column closest to your
actual supply. If your available line voltage is exactly midway
between two listed voltage levels, you may use either voltage
column. For example, in the 230 Volt table, if you have 212
available, use either the 208 or the 216 column.
3. Read down the available line voltage column until you reach
the rated load kVA of the equipment you want to operate or
“the next higher kVA” rating. For example, in the 230 Volt table
under the 208 available line voltage column, you want to operate an air conditioner rated 2 kVA. Since 2 kVA is not listed as
such, you must read down to the next higher value or 2.4 kVA.

4. Once you have established this point, read across to the far
left column for the exact GE buck-boost model number for
your application. For example, the 230 Volt table under the
208 column for a 2 kVA air conditioner, read across from 2.4
(next higher kVA rating) and the model number is 9T51B0107.
5. Connect the buck-boost transformer you have selected per
the connection diagram specified at the “bottom” of the available line voltage column you used. For example, if you used
the 208 column, you would connect the buck-boost transformer per connection diagram A. That’s all there is to it! The
transformer you’ve selected will meet your exact requirements
when connected in the specified manner.
The formula for calculating single-phase kVA is:
Load Voltage × Full Load Amps
1000
The formula for calculating three-phase kVA is:
1.732 × Load Voltage × Load Amps
1000

Open Core and Coil Transformers
Machine Tool and Control Power
Product Description
Core and coil transformers for machine tools are used to provide
voltage to control devices in applications where regulation and
minimum space are important. Welded cores provide the highest
quality electrical performance and quiet operation.
Standards: Type IP transformers conform to NEMA ST20
Listings: UL listed under UL-5085, File E2739

CSA Certified under C22.2, Number 66, File 3272
Insulation Classes: 150VA and below: 105°C insulation class,

55°C Rise
200VA and above: 185°C (NEMA)
180°C (UL) insulation class, 115°C Rise
Frequency: 60 Hz standard; 50 Hz optional.
Voltage Regulation: All designs 2.0 kVA and below are compensated for voltage drop. Compensation ranges from 10% in the
smallest rating to 3% for the largest. All machine tool designs
meet or exceed NMTBA regulation requirements.
Core and Coil Transformer

Series-Multiple Secondary Connections: Transformers with
120/240 V secondaries (series-multiple) may be connected for
120 V, 240 V or 240/120 V three-wire. Jumpers are provided.
Overcurrent Protection: Type IP transformers are low impedance
transformers that require overcurrent protection for most
applications. They provide for optional integral primary and/or
secondary fusing.
Mounting Dimensions: Type IP transformers are lightweight,
small, and designed for minimum mounting dimensions. Many
units will fit competitors mounting footprints.
