Type 1 surge protectors
Type 1 surge protectors are designed to be installed when a direct lightning strike risk is high, especially when the building is equipped with external lightning protection system (LPS or lightning rod).
Type 2 surge protectors
Type 2 surge protectors are designed to be installed at the entrance
of the installation, in the main switchboard, or close to
sensitive equipment, on installations without LPS (lightning
rods).
Type 3 surge protectors
In case of very sensitive or remote equipment, secondary stage
of surge protectors is required : these low energy SPDs could be
Type 2 or Type 3 (see «Coordination of surge protector» page 20).
