Rated discharge current I
sn
The rated discharge current is the peak value of an impulse current of the form 8/20 microseconds
(see fig.) for which the overvoltage protection module is designed, in accordance with a specified
test program.
Protection level U
:
sp
The protection level of an overvoltage protection module is the maximum instantaneous value of
the voltage at the terminals, determined from individual tests.
The protection level characterizes the ability of an overvoltage protection module to limit overvolt-
ages to a residual level.
