HSU8 series surge protector

Description

HSU8 series surge protector is suitable for the voltage power supply cabinets, power distribution cabinets, ac distribution panel, power distribution box, lighting box and some important equipment of power into the terminal, Damage caused by lightning and overvoltage (surge) used to protect electrical equipment from power supply lines. Class I test products,can be used for overhead lines without direct lightning protection. Protector uses high energy Varistors , can be used for arc extinguishing, intermittent flow requirements particularly high places of the first level of lightning protection.Class II test products First level (over voltage) protection for low voltage distribution system for building access. Such as the construction of low-voltage main distribution cabinet, outdoor power distribution control cabinet, as well as lightning risk higher lightning protection system.
