An AC Surge Protection Device (SPD) is a vital component used in electrical systems to safeguard sensitive equipment and appliances from voltage surges, also known as transient overvoltages. Voltage surges are sudden increases in voltage that can occur due to various reasons, such as lightning strikes, switching of large electrical loads, or power grid disturbances. These surges can damage or degrade electronic devices, causing malfunctions, reduced lifespan, or complete failure.
The main features of an AC Surge Protection Device are:
Product Benefits
The AC Surge Protective Device SPD T3, Class D, Class III TLP product line is distinguished by its modular devices' high-performance specifications and uncomplicated AC series design. The devices integrate safety and usability into a single module. They are useful for protecting terminal equipment in industrial electronic environments due to their low voltage protection level and extensive protection against common-mode and differential-mode interference.
