Type 2 and 3 surge protective devices shall be installed as close as possible to the sensitive equipment
to protect. As Type 2 they have been characterize by their capacity to safely discharge current with
a 8/20 µs wave form and they guarantee the coordination with Type 1 SPDs or other Type 2 respecting
coordination distances. As Type 3 they are characterized by their capacity to safely discharge current
with 1.2/50 µs wave form, with a very low level of Voltage Protection level.
