PRODUCT DESCRIPTION:
GE TR7000 Series are Type 2 Surge Protective Devices (formerly called TVSS), designed for
installation on low voltage electrical distribution systems. GE SPDs are designed to protect
electrical equipment loads against the damaging effects of transient voltages that can be
induced or generated as a result of remote lightning, power equipment switching or high
frequency disturbances.
The TR7000 Series SPDs incorporate Metal Oxide Varistor (MOV) technology to achieve superior
transient suppression performance. Integral to the SPD is a patented thermal fusing system that
offers SPD circuit interruption in the event of an abnormal phase overvoltage condition. Other
standard features include surge rated fuses, protection status indicating lights, an audible alarm
with test and disable features, form C alarm contacts for remote monitoring, a surge event
counter, and built in EMI filtering. A surge rated disconnect switch is comes standard on select
models.
The GE TR7000 SPD units described in this manual are enclosed, wall mounted styles that are
UL/cUL Listed, conforming to UL 1283 and UL 1449 3rd Edition where applicable. All published
ratings are in accordance with ANSI / IEEE C62.41.1-2002, C62.41.2-2002 and NEMA LS1-1992
(R2000) recommended guidelines.
Model covered by this manual are:
TR7000 model types ending with the part number suffix of WMN1D, WMN12S, WMN12F, WMN4D,
WMN4S and WMN4X. (Example: TR7277Y200WMN12S)
APPLICATION GUIDELINES:
Determining the surge protection to be provided in a facility or for a particular system or
equipment can be a complex task that should be addressed as early as possible. This is typically
when a new facility is constructed or sensitive electronic equipment has been installed. The
following guidelines are offered for application assistance:
Prior to installing any SPD, ensure that your facility electric supply system is properly
installed and connected in accordance with all applicable national and local codes and
safety procedures. All equipment and systems should be installed in accordance with
manufacturer’s instructions.
Utilize the personnel from your local utility, your engineering department, GE application or
service engineering, or a professional consulting engineering firm for technical guidance or
troubleshooting.
Understand your system, and the capabilities and limitations of SPD and other power
conditioning equipment.
Select the proper GE TR7000 Series SPD unit for your system voltage, configuration, and the
anticipated surge environment. Some of the key parameters for selection are defined below:
SPD TYPE
The SPDs covered in this document are rated and marked accordingly for use on Type 2
applications. Type 2 SPDs can be installed only on the load side of the electrical distribution
system’s main breaker or fuse.
2020004602 (12/10) Page 4 of 17
MAXIMUM CONTINUOUS OPERATING VOLTAGE (MCOV)
This value defines the maximum line-to-line or line-to-neutral continuous AC voltage that can be
safely applied to the protector. MCOV levels for GE TR7000 Series SPDs are set at 115% of nominal
system voltage. For 120-volt AC systems, the MCOV is 125%. If there is a risk that the electrical
system voltage could exceed MCOV, or if any unusually high power frequencies, Temporary Over
Voltages (TOV), or phase swells are anticipated, contact your GE Sales Engineer for further
assistance.
ELECTRICAL SYSTEM CONFIGURATION
Protectors are available for single (split) phase with neutral and ground, three-phase grounded WYE,
three-phase ungrounded WYE, three-phase high-leg delta, and for three-phase ungrounded delta
systems. (See page 7 for power source configurations)
PEAK IMPULSE RATING
Peak surge current capability is an important characteristic for a SPD. The rating per mode should
equal or exceed the maximum surge expected in service. GE TR7000 wall mount SPDs are available
in maximum surge ratings of 65kA, 80kA, 100kA, 125kA, 150kA, 200kA and 300kA.
UL 1449 NOMINAL DISCHARGE CURRENT (In)
The UL Nominal Discharge Current (In) rating should be considered when an SPD is selected for use
within a UL96A Lightning Protection System. UL96A requires a Nominal Discharge Current (In)
rating of 20kA for Type 1 or Type 2 SPDs.
SHORT CIRCUIT CURRENT RATING
GE TR7000 Wall Mounted SPD units are UL certified for use on electrical systems with rated
ampacities up to 200,000 symmetrical amperes when installed behind a circuit breaker rated 60A.
ENVIRONMENTAL RATINGS
NEMA Ratings of 1, 4, 4x, and 12 are available. Please refer to the model number suffix to verify the
correct enclosure for the application. The SPD is designed to operate within an ambient
temperature range of –40C (-40F) to +65C (+149F) with a relative humidity level between 0-95%
non-condensing.
A direct lightning strike, that occurs within close proximity of an installed SPD, can result in
surge currents that exceed the SPD’s energy handling capability. This can result in reduced
life expectancy or pre-mature failure of the SPD. Electrical power system supply voltages in
excess of the SPD MCOV rating, can also cause SPD failure.
Should a condition occur that results in premature failure of the SPD, the suppression
circuitry will short, allowing the integral fusing to interrupt current flow through the SPD
without disrupting power to the protected equipment. In the event of limited available fault
currents, the 60A breaker will operate to remove the SPD. Fault currents of less than 60A will
be interrupted by the integral thermal fusing. In each case the SPD will be removed from the
power system and the load equipment will remain unprotected from subsequent surge
activity until the SPD is replaced.
Increased rate of rise or higher surge current magnitudes can result in increased surge let-
thru levels due to the non-linear clamping characteristics of SPDs. Conditions can occur
where the surge withstand capability of the protected equipment is exceeded even though
the SPD is functioning properly. In such cases, additional SPDs may be required, located
closer to the sensitive load(s). (For additional information, refer to Standard IEEE 1100-2005,
Section 3.4.3)
GE TR7000 Series WYE-connected units have both normal mode (L-N, L-L) and common
mode (L-G, N-G) protection. Protection between neutral and ground is provided on units
designed for WYE-connected applications.

PRE-INSTALLATION REQUIREMENTS:
Prior to energization of the GE TR7000 SPD, it is critical that the following items have been
addressed.
DO NOT ATTEMPT TO ENERGIZE THE SPD OR CONTINUE WITH THE INSTALLATION IF
ALL OF THESE CONDITIONS HAVE NOT BEEN MET, OR ARE UNKNOWN.
1. SYSTEM CONFIGURATION AND VOLTAGE
Check the configuration and voltage supply ratings to ensure that the proper SPD model
number has been selected for your system. The SPD model number can be found on the UL
label affixed to the SPD NEMA Enclosure. The SPD selection can be verified by comparing the
Model Number to the correct electrical system described in the “VOLTAGE RATINGS & POWER
SOURCE CONFIGURATIONS” chart shown on page 7.
THE EQUIPMENT COVERED BY THESE INSTRUCTIONS SHOULD
BE INSTALLED AND SERVICED ONLY BY COMPETENT,
QUALIFIED PERSONNEL UTILIZING PROPER SAFETY PRACTICES
AND PROCEDURES THESE INSTRUCTIONS ARE WRITTEN FOR
SUCH PERSONNEL AND ARE NOT INTENDED AS A SUBSTITUTE
FOR ADEQUATE TRAINING AND EXPERIENCE IN SAFE
PROCEDURES FOR THIS TYPE OF EQUIPMENT.
2. SYSTEM GROUNDING AND BONDING
Verify that a NEC (National Electrical Code) compliant X0 bond has been made at the
upstream transformer or other separately derived system that feeds the SPD. Per NEC
Article 250.30, this bond must be in place on all 3-Phase WYE, 3-Phase Hi-Leg Delta, and
Single Phase Split-Systems. Refer to page 8 for an example of an installation that complies
with these NEC recommendations.
WARNING
FAILURE TO PROVIDE THE X0 BOND WILL DAMAGE THE
Verify that there have not been multiple instances of Neutral to Ground bonds on the
electrical system. These bonds, while either intentional or accidental, result in Ground
currents that can create differential voltage potentials between Neutral and Ground.
Redundant Neutral to Ground connections can result in damage to the SPD and are in
violation of NEC.
3. SPD INSTALLATION ON UNGROUNDED POWER SYSTEMS
Ungrounded power systems are inherently unstable and can produce excessively high lineto-ground voltages during certain fault conditions. During these fault conditions any
electrical equipment, including an SPD, may be subjected to voltages which exceed their
designed ratings. This information is being provided to the user so that an informed decision
can be made before installing any electrical equipment on an ungrounded power system.
2020004602 (12/10) Page 6 of 17
4. SPD LOCATION / PRIMARY OVERCURRENT PROTECTION
Per the National Electrical Code (NEC Article 285), Type 2 SPDs may be placed only on the
load side of the main service breaker or fuse at each utility service entrance or separately
derived power system.

WARNING
INSTALLATION:
Before attempting installation, make sure that the pre-installation requirements of this manual
have been satisfied. If the status of the pre-installation requirements are not known, do not
attempt to continue.
1. MOUNTING
The GE TR7000 Wall Mounted SPD must be installed as close to the protected circuit as
possible. Long power cable runs between the SPD and protected circuit will result in
significantly reduced performance.
Select a mounting location that will allow for a minimum length of wire between the SPD and
the power terminals of the electrical service panel. The SPD can be mounted in any
orientation, however special consideration should be given to allow for periodic inspection of
the diagnostic display panel. The SPD should be mounted to a secure structure or surface.

INSTALLATION (CONT.):
3. POWER CONNECTIONS
Mechanical terminals are provided on the SPD for connection to the electrical power system.
These terminals will accommodate #14 to 2/0 AWG stranded copper conductors. The
minimum recommended wire size for the GE TR7000 SPD is # 6 AWG. See page 13 for
terminal location and identification.
4. WIRE ROUTING
The length of wiring to the SPD must be kept at a minimum for the best performance. Wire
lengths should be short, strait runs between the SPD and power source. Wiring impedance
can be further reduced by twisting the phase, neutral and ground conductors together and
routed in the same raceway or channel. Always avoid sharp bends when routing SPD
connecting conductors.
5. CIRCUIT BREAKER
A dedicated 60 A or lower rated circuit breaker (not included) is required to connect the SPD
to the power system.
6. REMOTE ALARM CONTACTS
Remote Alarm Monitoring Contacts are provided on all SPD model types covered by this
manual. If this type of monitoring is desired, refer to page 13 for the location and pin
configuration of these contacts. The contacts are dry, 1 form C type, rated 120 VAC, 1 A (30
VDC, 2A) maximum. Once the SPD has been energized and is operating as intended, the
alarm contacts will switch to “Normal Status”. The contacts will only change back to “Alarm
Status” if there is a failure within the SPD suppression circuitry, or if power has been
disconnected from the SPD. Allowing the Remote Alarm Contacts remain unconnected will
not affect the performance or integrity of the SPD.
7. SPD DISCONNECT SWITCH
A manually operated disconnect switch is provided as a standard feature on some models.
It can be used to disconnect the SPD for servicing.
8. PRE-ENERGIZATION CHECK
Once all of the pre-installation conditions have been met and the GE TR7000 SPD has been
installed, the SPD can now be energized. For SPD Operational Status, refer to Operation and
Maintenance Sections – pages 15 & 16.

WARNING
OPERATION:
After applying power to the SPD, verify that the protection monitoring circuits are functioning
correctly. If all status alarms indicate “normal”, the SPD has been successfully installed and is
operational.
UPON ENERGIZATION OF THE SPD, IF ANY OF THE LAMPS OR ALARMS
INDICATES AN ABNORMAL CONDITION, POWER SHOULD PROMPTLY BE
DISCONNECTED FROM THE SPD. THE ELECTRICAL SYSTEM SHOULD BE
INSPECTED AND THE PRE-INSTALLATION REQUIREMENTS SHOULD BE
VALIDATED. DO NOT ATTEMPT TO LEAVE POWER APPLIED TO THE SPD, OR REENERGIZE THE SPD IN THE EVENT OF AN ALARM CONDITION. PLEASE
CONTACT YOUR LOCAL GE REPRESENTATIVE FOR FURTHER ASSISTANCE.

1. LINE STATUS INDICATOR LEDs
The green line status LED’s provide visual indication of SPD health status. As long as the SPD
is connected to the electrical system supply voltage and the SPD suppression circuitry is
functional, the line status indicators will be illuminated green. There is one green indicator
per each protected phase.
2. ALARM STATUS INDICATOR LEDs
When illuminated, the red Alarm Status Indicator LED will provide notification of a SPD failure
condition. Verify the Alarm Status Indicator is not illuminated upon startup.
3. REMOTE ALARM CONTACTS
Remote Alarm Contacts are available to remotely monitor the health status of the SPD. An
alarm condition will result in a status change of the contacts. These contacts do not affect
2020004602 (12/10) Page 15 of 17
the performance of the SPD and are not required to be connected for the SPD to function as
intended. (See pages 9 & 10 for Alarm Contact details)
4. TEST / ENABLE / DISABLE SWITCH
Enable Position - This is the normal position for the tri-position switch. In the Enable
position, the Audible Alarm will sound in the event of a SPD failure mode.
Disable Position – This position will silence the Audible Alarm if desired. The Disable
switch will not disable or disconnect the SPD from the electrical power system.
Test Position – The Test switch provides a quick diagnostic status of the Audible Alarm,
Alarm Status Indicator and Remote Alarm Contacts. When pressed, the Audible Alarm
will sound, the Alarm Lamp will illuminate, and the Remote Contacts will change state.
The “Test” position is momentary. Once pressed, the switch will automatically reset to
the “Enable Position” upon release.
5. SURGE COUNTER LCD
The (optional) Surge Counter will sense and record transient surge events that have been
mitigated by the SPD. The counter has been designed to detect transients that exceed the
peak sine wave by more than 70%. If desired, the Surge Counter Display can be reset to zero
at any time by pressing the reset button located on the LCD display.
MAINTENANCE:
GE does not provide a specific schedule for preventative maintenance as conditions will vary
based on location and the environmental factors presented at each installation site. However,
periodic inspections should be scheduled to verify that the SPD does not indicate a failure mode.
Inspections should also be made to check the integrity of the electrical supply connections to the
SPD to ensure continued reliable performance.
SERVICING / TROUBLESHOOTING:
The GE TR7000 Series SPD contains no user serviceable parts and requires no calibration. The
rugged design of the SPD should provide many years of service.
Should a condition occur that results in premature failure of the GE TR7000 SPD, the integral
fusing or required circuit breaker will safely interrupt current flow through the SPD without
disrupting power to the protected equipment. This will remove the SPD from the power
system and the load equipment will remain unprotected from subsequent surge activity until
the SPD is replaced.
If a change in operational status/alarm indication occurs, a qualified (licensed) electrician should
inspect the electrical system to verify electrical system integrity. If the SPD remains in alarm
after system inspection/corrections have been made, the SPD should be replaced. For further
assistance, contact your local sales representative or call GE Power Quality at 1-800-637-1738.
WARNING
IN THE EVENT OF AN SPD ALARM CONDITION, DO NOT ATTEMPT
TO DIS-ASSEMBLE THE SPD TO REPLACE FUSING OR OTHER
COMPONENTS. THE SPD CONTAINS FUSING COMPONENTS THAT
WILL ONLY OPEN WHEN THE SPD HAS FAILED IN A NONSERVICEABLE CONDITION. THE ENTIRE SPD MUST BE REPLACED.
