Term Definitions
This is the maximum peak current which may be applied
for a single 8/20μs impulse, with rated line voltage also
applied, without causing device failure. The pulse can
be applied to the device in either polarity with the same
confidence factor.
Peak value of the current, selected by the manufacturer,
through the SPD having a current waveshape of 8/20μs
where the SPD remains functional after 15 surges.
A rating selected from a list of preferred values as given
in UL 1449 and assigned to each mode of protection. The
value of VPR is determined as the nearest highest value
taken from UL 1449 to the measured limiting voltage
determined during the transient-voltage surge suppression
test using the combination wave generator at a setting of
6kV, 3kA.
This is the maximum continuous sinusoidal RMS voltage
that may be applied. This voltage may be applied at any
temperature up to the maximum operating temperature
of the device.

UL 1449
Limited Current Abnormal Over-voltage Test
An Underwriters Laboratory standard covering the safety
requirements for Surge Protective Devices intended for
permanently connected, cord-connected and direct plug-in
applications.
An AC over-voltage condition applied to a Surge Protective
Device according to UL 1449, Section 39.4. The short
circuit current is limited by series connected resistors
to 10A, 5A, 2.5A, 0.5A and 0.125A. The condition is
maintained for 7 hours or until the device under test
is disconnected from the AC supply or the current or
temperature reaches equilibrium.
This is the maximum rated transient energy which may be
dissipated for a single current pulse at a specified impulse
duration, with the rated RMS voltage applied, without
causing device failure.
This is the voltage at which the device changes from the
off (standby state) to the on (clamping state) and enters
its conduction mode of operation. The voltage value is
usually characterised at the 1mA point and has a specified
minimum and maximum voltage range.
