four-pole surge protector for installation in distribution boards

Product introduction

The toer surge protector is designed and manufactured according to the standard of IEC and GB, and meets the requirements of IEEE802.3AT. We use the brand components to make use of advanced production technology. It has the characteristics of large flow capacity, low residual pressure level, sensitive reaction, stable performance, reliable work and so on.
No matter what weather it is, you can rest assured that you can use it safely, and no longer need to worry about the harm of thunderstorm.

Working principle of product

Power surge protector is divided into two parts: explosion proof box type and modular type. A varistor with excellent nonlinear characteristics is adopted.
Under normal conditions, the surge protector is in extremely high resistance state, and the leakage current is almost zero, thus ensuring the normal power supply of the power supply system. When the power system surge overvoltage, the power surge protector immediately passes in the nanosecond time, limits the amplitude of the overvoltage to the safe working range of the equipment, and releases the surge energy into the ground. Then, surge protector rapidly changes to high resistance state, so that normal power supply is not affected.
