一、Application and characteristics

The three-phase integrated box-type power surge protector is designed according to IEC and GB. It makes full use of the advantages of MOV (pressure sensitive), GDT (gas discharge tube), and TVSS (transient diode) to avoid GDT leakage. Large flow has continuous flow, long response time, low residual pressure of MOV, TVSS, and small leakage flow. It is suitable for low-voltage power distribution systems such as telecommunications, smart buildings, airports, factories, power, railways, etc., electrical appliances, electronic equipment and interconnection of equipment System over-voltage and high-voltage static protection, over-voltage surge protection in the main power distribution system.

二、Technical Parameters

三、Product features

○ The integrated design of Siemens pressure sensitive, gas discharge tube and a variety of components embodies multi-level discharge, large lightning flow and high protection level;

○ Phoenix terminal, strong fire resistance, safe, reliable, and good maintainability;

○ Full protection design, low leakage current and low residual voltage;

○ Each discharge unit is equipped with hot melt protection and overcurrent protection;

○ Adopt fire and moisture-proof technical measures;

○ Equipped with an independent safety protective grounding (PE) busbar to prevent reverse connection;

○ Work status indication (lightning protection status means the light is on, failure or failure means the light is off);

○ Beautiful structure and convenient installation.
