Surge Protector, also known as SPD (Surge Protection Device), is a device used to protect electronic equipment, instrumentation and communication lines from voltage surges and current surges. Its main functions include:

Absorb and break down voltage surges: Surge protectors can absorb and break down sudden voltage surges in the power system, preventing these surges from causing damage to equipment connected to the power system. 

1.Limit overvoltage: When overvoltage occurs, the surge protector shunts and limits the voltage in parallel to prevent excessive current and voltage from damaging the equipment.  

2.Discharge surge current: The surge protector can discharge the surge current caused by lightning, power system switching, motor starting, etc.  12 Fast response time: The surge protector has a very fast response time and can trigger protective action immediately when a voltage surge or overvoltage occurs.  

3.Large current withstanding capability: Surge protectors can withstand large surge currents and effectively absorb and disperse the energy caused by voltage surges and overvoltages.

The aging mechanism of the surge protector includes the internal mechanism tripping in time to prevent fire when aging, while maintaining continuous effective lightning protection during lightning strikes. In addition, surge protectors can work stably in different harsh working environments, and the products have good consistency, ensuring that the indicators in each set of products remain consistent, thereby ensuring stable performance and extending service life.
