Features Quick response: under normal conditions, the protector is in a high strength state. When the power grid handles the surge due to lightning strike or other reasons, the surge protector quickly turns on in a few nanoseconds. Stable Operation: When the surge passes through the protector and disappears, the protector will change to a high-strength state again, so as not to affect the normal operation of the electrical network. Surge Protection: Mainly used to limit the amplitude of transient surges, absorb, consume or release surge current so that protected electrical components can be converted from one surge to another lower surge in high voltage. Wide Application Suitable for protecting household and similar electrical appliances from lightning induced surges and switching surges. EASY TO INSTALL - Compact size and lightweight also, the surge protection device supports the installation of 35mm electric rail, which can be completed in minutes.
