UltraMOV Series
Terms
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:
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
V
= Harris Varistor Designation
o
xx = Nominal Disc Diameter (07, 10, 14, 20mm)
of 85 C.
o
E
= Epoxy Encapsulation (Rated to 85 C)
Maximum Non-Repetitive Surge Current (I
)
xxx= V Voltage Rating (130V - 625V)
TM
M(AC) RMS
This is the maximum peak current which may be applied for
an 8/20µs 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 specified impulse
and duration (2ms), with the rated V
causing device failure.
applied, without
RMS
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 specified minimum and maximum voltage levels.
Clamping Voltage (V )
C
This is the peak voltage appearing across the MOV when
measured at conditions of specified pulse current amplitude
and specified waveform (8/20µs).
