| applied area | This standard applies to surge protection devices (SPD) from direct and indirect effects such as lightning or other transient voltages. These devices are packaged and connected to 50 or 60 Hz power circuits and equipment up to 1 000 V rms. This standard specifies the performance characteristics, standard test methods, and ratings of these devices. This device contains one or more nonlinear elements and is intended to limit surge voltage and convert surge current. | ||||||||||||||||||||||||
