‡UL 1449, 500A Test: A UL test setup (6" of cabling and low 500A, 8/20µs current waveform) to allow clamping voltage comparisons between SPD's made by different manufacturers. Since a protector in the field will experience a greater surge of transient energy, the low peak current of 500A does not properly reflect an SPD's true clamping and hence is of limited value.
