SPD (Surge Protection Device or called surge arrester) is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold. We have spark gap, MOV and Spark tube type for different protection area.
What are the main differences between MOVs and Spark Gaps in SPDs? | What are the main differences between Type 1 and Type 2 SPD?
What are the main difference between 8/20μs and 10/350μs in SPD?

T2 Surge Protectors:
T3 Surge Protectors:
The combination of T1, T2, and T3 surge protectors can provide a comprehensive protection system for an electrical installation, from the main service entrance to the individual sensitive devices.
