The AC Surge Protective Device is for protecting electrical systems from high-energy surges such as lightning. It works in a fast manner, with an array of discharge capacitance. It provides consistent performance to ensure the safety of the equipment it is charged with. Intended for home and business applications, this unit complies with safety standards in various countries to provide you with the finest security each time.
· 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).
According to different lightning protection areas, AC Surge protective device is divided into four categories: Type 1, Type 2, Type 3 and Type 1+2 Surge protective devices.
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.
