GE Industrial Solutions GE TR5000 Series - Manual (Page 4)

2020004403 (12/09) Page 4 of 18
PRODUCT DESCRIPTION:
GE TR5000 Series Type 2 Surge Protective Devices (formerly called TVSS), are 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 TR5000 Series SPD 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 a limited current abnormal overvoltage condition.
Other standard features include protection status indicating lights and form C alarm contacts for
remote monitoring. TR5 65KA - 100KA RATED models also include surge rated fuses and built in
EMI filtering.
The GE TR5000 SPD units described in this manual are enclosed, wall mounted styles that are
UL/cUL Listed, conforming to UL 1283 and UL 1449 3 rd 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:
TR5000 model types ending with the part number suffix WM, WMF, or WM4
(Examples: TR5120Y050WM, TR5277Y100WMF, TR5240D025WM4)
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 TR5000 Series SPD unit for your system voltage, configuration, and the
anticipated surge environment. Some of the key parameters for selection are defined below:
 SPD T YPE
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.
