AC Surge Protective Device T1+T2 25kA FLP25GR series
Surge protective device SPD, arrester type 1+2 (class I+II, class B+C) for use in AC power supply systems.
The AC Surge Protective Device T1+T2 25kA FLP25GR line is a group of Class I+II Surge Protective Devices. They are intended as a protection against indirect and low-intensity direct hits of lightning strokes. In standard three-phase TN-C grid, they provide protection to LPL III, IV requirements given in EN 62305 with total lightning current introduced into electrical installation of 75 kA and total lightning stroke current 150 or 200 kA based on physical configuration and mutual position of grounding point of lightning rod, grounding point of the electrical installation and place of SPD installation.
The design of FLP25GR is based on Graphite (Spark Gap). Such design provides low-response time and ensures characteristics for both classes I and II. Prewired spark-gap-based type 1 and type 2 combined lightning current and surge arrester. Maximum systems availability due to RADAX Flow follows current limitation. Capable of protecting terminal equipment.
