IEC 63093-1:2020 specifies the dimensions and allowable limits of surface irregularities of ferrite cores. It is intended that this document excludes ferrite cores which are specialty cores with limited use. Also, special cores which are only marginal variations upon standard cores are excluded. IEC publishes electrical standards for families of ferrite cores, as well as this series of…

IEC 62841-2-3:2020: applies to hand-held grinders, disc-type polishers and disc-type sanders, including angle, straight and vertical tools, intended for use on various materials except magnesium, with a rated capacity not exceeding 230 mm. For grinders, the rated no-load speed does not exceed a peripheral speed of the accessory of 80 m/s at rated capacity. This standard does not apply to…

IEC 60282-1:2020 applies to all types of high-voltage current-limiting fuses designed for use outdoors or indoors on alternating current systems of 50 Hz and 60 Hz and of rated voltages exceeding 1 000 V. This eighth edition cancels and replaces the seventh edition published in 2009. This edition includes the following significant technical changes with respect to the previous edition: –…

IEC 61754-35: 2020 defines the standard connector interface dimensions for LSHE family of connectors with up to four termini. This connector family is targeting deployment under harsh environmental conditions.
