Introduction
I
Voltage spikes and surges from both external and
internal sources can cause damage to all electronics
and directly affect the performance and life expectancy
of connected equipment. From electronic lighting
ballasts to computer servers, if there is a printed circuit
board inside, it can be susceptible to transient voltage
surge damage. As microprocessors and components
that make up this equipment grow smaller and faster with
each new generation, their susceptibility to transient
voltage surge damage becomes ever greater.
Available in ratings from 65kA - 300kA per mode,
(130kA - 600kA per phase) the TR7000 series is the
perfect surge suppression product for protecting critical
sensitive electronic equipment throughout your facility.
The full-featured TR7000 Series with its advanced
monitoring, disconnect and enclosure options has been
designed to handle the highest levels of surge activity
found in the most demanding commercial and industrial
facilities. These units are ideal for both new and retrofit
applications where performance cannot be compromised.
TR7000 Series
Surge Protective Device (SPD)
with Enhanced Thermal Protection
Recommended installation locations are service entrance
and primary and secondary distribution. The TR7000
Series has been third-party tested to the ANSI/IEEE C3
(10kA, 8x20μs) service entrance level transient surges
including all components. The entire TR7000 line up
has been engineered to the highest standards and is
designed for rigorous duty and long life as evidenced
in our outstanding minimum repetitive surge current
capacity test results.
Features and Benefits
Applications
> Thermally protected MOVs eliminate the need for
additional upstream overcurrent protection
> The TR7000 provides maximum surge protection with
outstanding clamping characteristics for ultra high,
high, medium and low exposure locations with the
use of industrial-grade MOV architecture.
> Third-party tested per IEEE C62.62 and NEMA LS-1
for the rated 8x20μs surge current, per mode with
fusing included.
> Fast rise-times, high frequency transients and
electrical line noise are reduced with standard
EMI / RFI filtering technology.
> Maximum installation flexibility is achieved in the
TR7000 through its high surge suppression kA to
small footprint ratio.
> 10 modes of protection (L-N, L-G, N-G, L-L)
> Service Entrance
> Distribution Equipment
> Green phase protection status LEDs with
Red alarm LED
> NO/NC Form C Dry Contacts for remote monitoring
> Industrial sized MOV technology
> Audible alarm with push-to-test switch,
enable/disable function
> Standard LCD surge counter
> Optional 200kA surge rated disconnect
> NEMA 1, 12, 4 and 4X enclosures available
