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.
