Features Quick Response: The protector quickly activates within nanoseconds to divert overvoltage, safeguarding electrical equipment from strikes and other power grid s. Stable Working: After the voltage passes through, the protector returns to a high-resistance state, ensuring the normal of the power grid is not affected. defence: Limits transient overvoltage, absorbs current, and converts overvoltage to a lower level, offering vital defence to electrical components. Wide Application: Ideal for safeguarding household and similar electrical appliances against induced overvoltage and switching overvoltage. Easy to Install: Compact and lightweight protective device supporting 35mm electric rail installation, allowing for quick and effortless setup. Features: 1、Quick Response: Under normal condition, the protector is in the state of high resistance. When the power grid handles the overvoltage due to stroke or other reasons, the protector will be turned on quickly within nanoseconds, introducing the overvoltage to the ground, thus protecting the electrical equipment on the power grid. 2、Stable Working: When the voltage passes through the protector and disappears, the protector will change to a high resistance state again, so as not to affect the normal of the power grid. 3、 defence: Mainly used to limit the amplitude of transient overvoltage, absorb, consume or discharge the 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 overvoltage and switching overvoltage. 5、Easy to Install: Compact in size and light in weight as well, the protective device supports 35mm electric rail installation, which can be finished in minutes.
