Test methods/conditions
The voltage between two terminals with
the specified measuring current applied
is called V
The maximum voltage between two
terminals with the specified standard
impulse current (8/20 µs) applied.
CECC 42 000, test C 2.1
100 surge currents (8/20 µs), unipolar,
interval 30 s, amplitude corresponding
to derating curve for 100 impulses
at 20 µs
CECC 42 000, test C 2.1
100 surge currents (2 ms), unipolar,
interval 120 s, amplitude corresponding
to derating curve for 100 impulses
at 2 ms
The varistor should be subjected to
V
until it failed, in series with 5 A fuse and
5 Ω resistor (based on S14 series).
