Type 2 SPDs provide protection from over-voltage surges due to indirect lightning strikes hitting the building or surrounding area and switching surges (8/20 µs waveform). They are necessary for second level of protection in applications where Type 1 protectors are installed upstream. They are also used for first stage of protection in residential, commercial or industrial applications not exposed to direct strikes or with no external lightning protection system.
Type 2 SPDs are suitable for use at the entrance of the installation (main DB), in intermediate distribution boards (sub DB) and by the terminal equipment.
