Audited Supplier 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:
