What does peak surge current mean?

Product Line: 
Surge Protective Devices (SPD's)

Resolution:
The peak ampere surge current ratings of an SPD are generally based on the summation of the capacities of the peak ampere rating of the individual suppression components used within a particular protection mode. Both line-neutral (L-N) and line-ground (L-G) modes are added together to represent a peak ampere rating per phase. (I.e. L-N 100 kA, L-G 100 kA provides 200 kA/phase).
