Surge protection switch SPD The best product of Thor brand surge
protective device
product description
Surge protector lightning protector is used to protect sensitive
lines from lightning induction voltage, power grid voltage
fluctuation, electrostatic discharge and surge voltage caused by
large load start-up.
It is widely used in family housing, third industry and industrial
field.
Structure and Principle
SPD is a port, shocking protection, indoor-mounted installation,
voltage-limited.
SPD hold disconnector inside, when SPD breakdown failure by over
heating, the disconnector can remove from the power grid
automatically, and show indication signal. When SPD is working
properly, visible window display green, it display red when it
breakdown and disconnect.
1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD+NPE zero ground
protection module, apply to TN-S, TN-C-S and other power supply
system.
Product features
1. cut off the line when undervoltage occurs, and reset
automatically after restoration.
2. the speed of response is 0.001 seconds, and the voltage is
controlled in the range that the equipment can withstand.
3. traffic flow to further improve safety

Working principle of product
Surge protector and its voltage limiting functional element are
composed of metal oxide varistors in parallel. Each varistor
requires an independent disconnector. The principle of the
disconnector is a heat release. The function is disconnected
through the low temperature welding point and is separated from the
metal rod by its own elastic action. After disengagement, the red
indication will appear in the transparent window on the front side
of the surge protector. It is installed in the main power
distribution cabinet and outdoor power distribution cabinet.
Use of attention
1. connect the grounding wire of the lightning protector with the
ground wire of the lightning protection system.
2. lightning arresters are connected in series
3. lightning protection device IN as input and OUT as output, the
input end is connected with the outside, and the output end of the
input end of the connecting device is protected.
