DESCRIPTION
BS EN 61643-11:2012+A11:2018
This standard BS EN 61643-11:2012+A11:2018 Low-voltage surge protective devices is classified in these ICS categories:
- 29.240.10 Substations. Surge arresters
- 29.240.01 Power transmission and distribution networks in general
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. power circuits, and equipment rated up to 1 000 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.
