3 - Type 3 / Class III

These Type 3 Surge Protection Devices have a low discharge capacity. They must therefore mandatorily be installed as a supplement to Type 2 Surge Protection Devices and in the vicinity of sensitive loads.

Type 3 SPD is characterized by a combination of voltage waves (1.2/50μs) & current waves (8/20μs).
