Power surge protective device 20KA lightning arrester protection voltage surge

Surge Protector and Circuit Breaker Installed together to Protect Power Lines


Product introduction


urge protector is used to protect the line from damage caused by lightning induced voltage, power interference, electrostatic discharge and so on. Surge protector adopts multi-stage protection circuit, selects brand components, and uses advanced production technology to manufacture, with low flow through residual pressure level.



Product features


1. adopt the latest arc extinguishing technology to avoid fire.


2. with the power status indication, indicating the working state of surge protector.


3. built-in overheating and temperature control circuit breaker


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.

Working principle of product


The function of surge protector is to limit the transient overvoltage to the power line, the signal transmission line in the voltage range that the equipment or system can bear, or to inflow the powerful lightning discharge into the ground, and protect the protected equipment or system from damage by the impact.


Use of attention


1. determine the discharge current path


2. in order to avoid unnecessary induction loops, we should mark the PE conductor of each device.


3. the energy coordination of multilevel SPD


Company profile


Thor is all about protecting against the damaging effects of power transients. It is our goal and mission to connect our customer challenges with high-quality, right-priced solutions and products – completed by unrivaled customer service and technical support.
