Product Description

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.

AC Surge Protection Device SPD Type 1 2, T1 T1, B C, I II, Iimp 10kA,lmax 100kA is designed to be the best possible solution for protecting service entrances at industrial sites, particularly those with existing lightning protection systems or mesh cage applications. This sort of surge protection can protect all electrical installations from lightning strikes by discharging the current generated by a lightning surge and preventing its spread to the equipment. The current waveform of the Type 1 2/Class B C, I II SPD is 10/350 μs.
