| applied area | This standard describes the principles for selection, operation, location, and coordination of SPDs for connection to 50/60 Hz AC power circuits and equipment rated up to 1 000 V RMS. The device contains at least one nonlinear component and is intended to limit surge voltages and dissipate surge currents. NOTE 1 Additional requirements for special applications may also apply if necessary. NOTE 2 IEC 60364 and IEC 62305-4 are also applicable. NOTE 3 This standard covers only SPDs and does not cover surge protection components (SPC) integrated inside the equipment. | ||||||||
