What is a per mode vs. per phase protection rating?

Product Line: 
Surge Protective Devices (SPD's)

Resolution:
Per mode rating is a voltage of Line to Neutral (L-N) OR Line to Ground (L-G). Per phase rating is 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).​ All of the literature for Schneider Electric surge protection products reflect the "per phase" ratings.
