AC Surge Protection Device T1+T2 12,5kA FLP12,5 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 Protection Device T1+T2 12,5kA FLP12,5 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 the electrical installation of 50 kA and total lightning stroke current 75 or 100 kA based on physical configuration and mutual position of grounding point of the lightning rod, grounding point of the electrical installation and place of SPD installation.
The design of FLP12,5 is based on high energy Metal Oxide Varistors. Such design provides low response time and ensures characteristics for both classes I and II. The modular design with plug-in inserts allows simple and quick replacement of function modules in case of MOV is beyond if its lifespan due to high intensity or often occurrence of overvoltage peaks.
