These new requirements are contained in the standard for household appliances IEC/EN 60335-1, which has been a long time established standard, particularly due to the prevalence of such unattended appliances, such as coffee machines.
All manufacturers of fuse holders must therefore check the glow wire resistance of the materials being used and, if necessary, replace the material. It is also necessary to update the approvals and to carry out a re-examination by the certification body. In case of a material change, the tests according to UL 4248.1 must also be repeated. By October 08 2017, Schurter will have adapted the complete range of its IEC-certified fuse holders to the new standard, including power entry modules with fuse holders.
