LT series surge protective devices are designed and manufactured according to GB18802.1-2011 and IEC 616343-1:2005. They are suitable for AC 47-63Hz's power supply system such as TT, IT and TN, so as to prevent all kinds of electronic and electrical equipment from lightning overvoltage. Such as instrument dc power supply, PLC dc power supply, electronic detection equipment dc power supply lightning protection.
Under normal conditions, the surge protector is in a high resistance state. When the surge or overvoltage occurs due to lightning or other reasons, the protector will rapidly lead in the nanosecond time, and the surge and overvoltage will be introduced into the earth, thus protecting the power equipment on the grid. When the surge overvoltage is disappearing, the protector is restored to a high resistance state. It does not affect the normal operation of the power grid and equipment.
