4P class I Surge Protection Device low voltage surge arrestor SPD
low voltage surge arrestor Product Description:
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.

· For electrical installations.
· Suitable for lightning protection of power supply system in areas with high risk of lightning strike (LPZ0B or interface between LPZ0B and LPZ1).
· Can handle lightning currents and protect sensitive electronic equipment.
· Application-optimized and prewired combined lightning current.
· Particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (e.g.: buildings equipped with lightning rods).
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.
