<!-- NEW! -->IEC 60077-5:2019 is available as <a href="https://webstore.iec.ch/publication/66005">IEC 60077-5:2019 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.</br></br>IEC 60077-5:2019 give additional or amended rules for high voltage (HV) fuses as a supplement to those given by IEC 60077-2. The high voltage fuses concerned are those connected into power and/or auxiliary circuits. The nominal voltage of these circuits lies between 600 V DC and 3 000 V DC, according to IEC 60850. These fuses can also be used in auxiliary AC circuits up to a nominal voltage of 1 500 V. This document together with IEC 60077-2 states specifically: a) the characteristics of the fuses; b) the service conditions with which the fuses comply with reference to: - operation and behaviour in normal service; - operation and behaviour in case of short circuit; - dielectric properties. c) the tests intended for confirming the compliance of the fuse with the characteristics under the service con
