Applictaion:

Type 1 surge protector is mainly installed in the building's main distribution board as the first level lightning protection of the building's power distribution system.

Protect electrical equipments from the direct lightning strikes.

Installation and Maintenance:

Generally installed on the main switchboard for protection.

Buildings with a large number of private areas (apartment buildings, office buildings, etc.) : If Type 1 surge protection cannot be installed, must be installed Type 2 surge protector at the entrance to each area.
