What does peak surge current mean?

Product Line: 
Surge Protective Devices (SPD's)

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).
