1. Protection: When there is a overvoltage, this protector will turn on quickly within nanoseconds, introduce the overvoltage into the ground, protect the electrical equipment.
2. High Performance: The protector has quick response speed, strong carrying capacity, and will not affect the normal operation of the power grid.
3. Fault Indication: There is a working status indication window, green means normal, red means fault, which can effectively reflect the working status and facilitate timely replacement and maintenance.
4. High Safety: The protector is fire and resistance, adopts insulated terminal blocks, more reliable and safe, supports hot line operation and is easy to use.
5. Rail Installation: The protector is modularly designed and adopts 35mm electrical rail installation method, simple and convenient.

Main Structure and Working Principle:
In a three phase four wire system, protectors are connected between three phase wires and one neutral wire to ground. Under normal circumstances, the protector is in a high resistance state, when the power grid deals with overvoltage due to strike or other reasons, the protector will turn on quickly within nanoseconds, and introduces the voltage overvoltage into the ground, thus protecting the electrical equipment on power grid. When the voltage passes through the protector and disappears, the protector changes to a high resistance state again, so as not to affect the normal operation of the power grid.
