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.
