BS EN IEC 61643-331:2020
This standard BS EN IEC 61643-331:2020 Components for low-voltage surge protection is classified in these ICS categories:
- 31.040.01 Resistors in general
- 29.120.50 Fuses and other overcurrent protection devices
- 31.040.20 Potentiometers, variable resistors
IEC 61643-331:2020 is a test specification for metal oxide varistors (MOV), which are used for applications up to 1 000 V AC or 1 500 V DC in power lines, or telecommunication, or signalling circuits. They are designed to protect apparatus or personnel, or both, from high transient voltages. This document applies to MOVs having two electrodes and hybrid surge protection components. This document also does not apply to mountings and their effect on the MOV’s characteristics. Characteristics given apply solely to the MOV mounted only in the ways described for the tests. This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - a Varistor MCOV rating assurance test; - an energy rating test (2ms); - revised Dielectric strength and insulation resistance tests.
