DESCRIPTION

BS EN IEC 61643-352:2018


This standard BS EN IEC 61643-352:2018 Components for low-voltage surge protection is classified in these ICS categories:
  • 33.040.99 Other equipment for telecommunication systems
IEC 61643-352:2018 covers the application of surge isolation transformers (SITs) that are used in telecommunication transformer applications with signal levels up to 400 V peak to peak. These transformers have a high rated impulse voltage with or without screen between the input and output windings. SITs are components for surge protection and are used to mitigate the onward propagation of common-mode voltage surges. This document describes SITs' selection, application principles and related information. This document does not cover power line communication transformers.
