The International Electrotechnical Commission (IEC) is the organisation responsible for preparing and publishing international Standards for all electrical components, electronics and technical equipment.
The IEC International Standards are guidelines providing universally accepted and standardised rules, regulations, and specifications for electrical, electronic, and technical components. These standards are crucial for quality and risk management in electrical maintenance. They help engineers better understand the equipment they are working on and allow manufacturers to produce products of consistent quality and performance.
The IEC symbols (also known as the IEC 60617 (British Standard BS 3939)) are graphical representations of various electrical and electronic components used in circuit schematics and diagrams. They provide internationally recognised imagery for electricians, engineers, and technicians to follow, allowing for a more consistent approach to manufacturing and maintaining electronics and technical devices while following a set of standard specifications.
Many of the IEC symbols can be quite difficult to remember and draw. Fortunately, you can skip this time-consuming process with Capital X Panel Designer! This electrical CAD software contains an extensive library of pre-made, IEC-standardised electrical symbols that you simply drag and drop onto your schematic drawing. You can even copy-and-paste any symbols you need multiples of, greatly improving your production speed.
