IEC 61643-11 Testing

Low-voltage surge protective devices – Part 11: Surge protective devices connected to low-voltage power systems – Requirements and test methods

IEC 61643-11 Scope:

IEC 61643 11 and EN 61643 11 testing 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. power circuits, and equipment rated up to 1000 V r.m.s. Performance characteristics, standard methods for testing and ratings are established. These devices contain at least one nonlinear component and are intended to limit surge voltages and divert surge currents.

 IEC 61643-11 and EN 61643-11 test compliance.
