- Type 3 SPD installed close to the protected load.
What is a Type 2 surge protector?
The Type 2 Surge Protection Devices are the main protection system for all low voltage electrical installations. Installed in each electrical switchboard, it prevents the spread of any overvoltages in the electrical installations and protects the loads. Type 2 SPD is characterized by an 8/20 µs current wave.
