IEC 61643-1: Edition 2.0
SDO: IEC: International Electrotechnical Commission
DOD Adopted ANSI Approved Approved
This part of IEC 61643 is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are packaged to be connected to 50/60 Hz a.c. and d.c. power circuits, and equipment rated up to 1000 V r.m.s. or 1500 V d.c. Performance characteristics, standard methods for testing, and ratings are established for these devices that contain at least one nonlinear component that is intended to limit surge voltages and divert surge currents.
