Surge Protective Device 3P 40KA 420V Voltage Protection Arrester Protector for Safety

About this item

• Feature: 1. Quick Response: Under normal condition, the protector is in the state of high resistance. When the power grid handles the surge overvoltage due to lightning stroke or other reasons, the surge protector will be turned on quickly within nanoseconds, introducing the surge overvoltage to the ground, thus protecting the electrical equipment on the power grid. 2. Stable Working: When the surge voltage passes through the protector and disappears, the protector will change to a high resistance state again, so as not to affect the normal operation of the power grid. 3. Surge Protection: Mainly used to limit the amplitude of transient overvoltage, absorb, consume or discharge the surge current, so that the protected electrical components can be converted from overvoltage to another lower overvoltage in the case of higher overvoltage. 4. Wide Application: Suitable for protecting household and similar electrical appliances against induced lightning overvoltage and switching overvoltage. 5. Easy to Install: Compact in size and light in weight as well, the surge protective device supports 35mm electric rail installation, which can be finished in minutes.
