Have you seen electrical drawings? It has only symbolic representation. Sometimes if you have not come across a particular symbol it is very hard to further interpret the electrical drawing.
Whether you are an electrical design engineer, maintenance engineer, or a student working on an electrical project knowing these symbols is surely beneficial.
I have worked with many MNC’s and what I have observed is the majority of companies do follow standards.
Before, I give you the list let me tell you the reason behind the standardization of electrical symbols.
In every nooks and corner of the world, whether it’s a metro rail project, a bullet train project, building automation project, or even in plant maintenance, Electrical Engineers have to come across Electrical drawings.
Imagine – a group of engineers working in an organization starts making their symbols for representation.
Each organization would have its own symbolic representation right!
In that case, a transformer could have been represented in thousand different ways.
It is very difficult to remember all those symbols.
So, standardization is necessary.
Here, I am listing out 100+ Electrical Symbols as per IEC standard 60617.
Annunciators IEC Symbols
Batteries IEC Symbols
Circuit Breakers IEC Symbols
Contacts IEC Symbols
Contactors IEC Symbols
Counters IEC Symbols
Disconnectors / Isolators IEC Symbols
Emergencies IEC Symbols
Fuses IEC Symbols
Inductors IEC Symbols
Limit Switches IEC Symbols
Motors IEC Symbols
Overload Trips IEC Symbols
Pilot Lights IEC Symbols
Push Buttons IEC Symbols
Relays IEC Symbols
Timers IEC Symbols
Transformers IEC Symbols
So these the electrical symbols you would find commonly in industry. Hope you like it. If you need still more, comment in the section below.
