Overvoltage circuit-breaker SPD HD-LED20/280P10

HD-LED20/280P10 is a new intelligent product that combines surge protection and overvoltage disconnection. This product has internal high-performance semiconductor surge absorbing device with accurate clamp and extremely low residual voltage, which can effectively restrain lightning overvoltage and surge pulse. At the same time, when the power supply line has an overvoltage, the power supply can be cut off quickly and safely to prevent the abnormal voltage from causing damage to the equipment at the back end. When the voltage become normal, the power supply can be automatically connect again and resume normal operation. Characteristic of product： 1. It has excellent lightning protection capability, large capacity, low residual voltage and fast response; 2. Overvoltage breaking ability, when the voltage is too high, the power is automatically cut off to protect the back-end equipment; 3. Self-recovery function.When the overvoltage is removed,it will automatically restore the power of the back-end equipment; 4. Optional working status indicator function.When overvoltage, the working indicator is off.
