The CMV-TVSS™
system is designed for direct application on motor
starters and switchgear. Because of its compact
design, the MV-TVSS™ can be mounted inside
or on the outside of most medium voltage switchgear
and motor starters. The compact design also enables
the MV-TVSS™ to be applied within motor or
transformer terminal housing giving complete protection
to all surges that may damage or fatigue a motor
or transformer’s insulation system.
Figure 1 shows
how the compact design enables the protection
unit to be mounted directly within or on the outside
of a motor starter. The direct mounting of the
surge protection unit means the lead length can
be made as short as possible, providing the maximum
protection for the motor.
Installation
is simple. Medium voltage conductors
are provided for connection to the switchgear
terminals, bus, or sensitive load. Mount the CMVTVSS™
, terminate the phase cables, connect the provided
ground conductor, and installation is complete.

Enclosure
11
Gauge Galvanneal Steel all welded construction.
Painted inside and out with a marine epoxy ANSI
61 gray paint. Wall mounted flanges are provided
as standard.
Conductors
All internal conductors
consist of low resistance Copper conductor. External
phase conductor leads are non-shielded and rated
for the system voltage class.
Ground Terminal
Grounding Provisions furnished
by external 5' copper ground lead.
Standards
5Complies with the latest
revision of ANSI/IEEE C61.11 "IEEE Standard
for Metal Oxide Surge Arresters for AC Power Circuits.
Current
Limiting Fuses
Disconnects the CMV-TVSS
in the event of an MOV failure. Fuses and MOV's
are not replaceable.

Surge
Arresters
The
CMV-TVSS is equipped with MOV arresters that are
designed and tested in accordance with ANSI/IEEE
C62.11 and IEC 99-4. The MOV's provide exceptional
over-voltage protection characteristics while
conducting less than one milliampere under normal
system conditions.
Encapsulation:
The MOV's and fuses are
encapsulated in a UL rated, high dielectric potting
compound. The potting compound provides the necessary
dielectric between phase and ground allowing for
a compact weather tight design.
