AC Surge Protective Device SPD Type 1+2, T1+T2, Class B+C, Iimp 25kA FLP25 series
High Energy MOV and GDT based type 1 and type 2 combined lightning current and surge arrester for use in AC power supply systems.
Type 1+2 surge protectors are heavy-duty devices, designed to be installed at the origin of the AC installations equipped with LPS (Lightning Protection System). They are necessary to protect sensitive equipment connected to AC network against direct and indirect effects of lightning. Following the different national electrical codes, these SPDs can be recommended or mandatory. These surge protectors are tested following Class I (T1, Class B) tests from IEC&EN 61643-11, characterized by 10/350 μs lightning current injections.
These surge protectors are available in a wide range of versions to be adaptable to all configurations:
Iimp by pole: 25 kA
Total Iimp: up to 100 kA
Single, 3 or 3-Phase+Neutral AC network
230/400 V, 120/208 V and 690 V AC network
All AC system types
Common mode protection (CT1 configuration) or Common and Differential mode protection (CT2 configuration)
The design of FLP25 is based on High Energy MOV and GDT. Such design provides low-response time and ensures characteristics for both classes I and II. hybrid MOV+GDT combined surge protective device SPD, spark gap.
Q1: Selection of surge protector
Al: The grading of the surge protector (commonly known as lightning protection) Is assessed according to the IEC61024 subdivision lightning protection theory, which is installed at the junction of the partition. Technical requirements and functions differ. The first-stage lightning protection device is installed between the 0-1 zone, high for the flow requirement, the minimum requirement of EN 61643-11 / IEC 61643-11 is 25 ka (10/350), and the second and third levels are installed between the 1-2 and 2-3 zones, mainly to suppress the overvoltage.
