UltraMOV Series
Model Number Nomenclature
The UltraMOV Series follows a different part numbering
procedure than other Harris Varistor products. The base part
number consists of the following:
V =
xx =
E =
xxx =
Harris Varistor Designation
Nominal Disc Diameter (07, 10, 14, 20mm)
Epoxy Encapsulation (Rated to 85
o
C)
V
M(AC) RMS
Voltage Rating (130V - 625V)
Terms
Rated AC Voltage (V
M(AC)RMS
)
This is the maximum continuous sinusoidal voltage which
may be applied to the MOV. This voltage may be applied at
any temperature up to the maximum operating temperature
of 85
o
C.
Maximum Non-Repetitive Surge Current (I
TM
)
This is the maximum peak current which may be applied for
an 8/20碌s impulse, with rated line voltage also applied,
without causing device failure. (See Figure 2)
For example, the model number for a 7mm epoxy coated
Varistor rated at 440V RMS is V07E440. (Note that this
number will be abbreviated to accommodate marking (laser
branding) of the Varistor body. (The part number brand is
shown in the Device Ratings and Characteristics table.)
Maximum Non-Repetitive Surge Energy (W
TM
)
This is the maximum rated transient energy which may be
dissipated for a single current pulse at a speci鏗乪d impulse
and duration (2ms), with the rated V
RMS
applied, without
causing device failure.
Nominal Voltage (V
N(DC)
)
This is the voltage at which the device changes from the off
state to the on state and enters its conduction mode of
operation. This voltage is characterized at the 1mA point and
has speci鏗乪d minimum and maximum voltage levels.
Clamping Voltage (V
C
)
This is the peak voltage appearing across the MOV when
measured at conditions of speci鏗乪d pulse current amplitude
and speci鏗乪d waveform (8/20碌s).
