AC Surge Protection Device Class B, I, T1 50kA FLP50GR series
Surge protective device SPD, arrester type 1 (class I, class B) for use in AC power supply systems.
Surge protection portfolio includes solutions for protecting systems up to 600 V a.c. against surges caused by atmospheric discharge and switching operations.
LSP is the line of AC power surge protectors is designed to cover all possible configurations in low voltage installations. They are available in many versions, which differ in
- Type 1
- AC network configuration (Single/3-Phase)
- Discharge currents (Iimp, Imax, In)
- Protection technology (varistors, GDT, graphite)
- Feature (compact)
The AC Surge Protection Device T1 50kA FLP50GR line is a group of Class I Surge Protective Devices. They are intended as protection against direct hit of lightning strokes of high intensities or in installation with frequent occurrence of lightning strokes. In standard three-phase TN-C grid, they provide protection over LPL I requirements given in EN 62305 with total lightning current introduced into electrical installation over 100 kA and total lightning stroke current 210 or 280 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 AC Surge Protection Device T1 50kA FLP50GR is fully based on the Spark Gap solution. It brings very high capability and lifetime and full insulation in case of no overvoltage is present. Thus, these SPDs can be used also upstream to energy meters and can be intended for IT grids (with respective special tests).
The high value of Iimp makes these SPDs suitable also for single-phase outlets which are wired out of LPZ 0-1 and thus can be hit with a direct lightning stroke. Due to the single-phase cable, the total lightning current is split to 3 conductors only and intensity per conductor is thus higher than in the case of ongoing three-phase cable.
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 50 ka (10/350), and the second and third levels are installed between the 1-2 and 2-3 zones, mainly to suppress the overvoltage.
