Electrical Symbol Library

The Electrical IEC 617 library includes the majority of symbols contained in the following parts:

  • Symbol Elements
  • Conductors and connecting devices
  • Passive components – resistors, capacitors, inductors etc
  • Semiconductors
  • Production and conversion of electrical energy
  • Switchgear, control gear and protective devices
  • Measuring instruments, lamps and signaling devices

These Electrical Blocks are organized!

Within AutoCAD add-on menus are also provided for use with the electrical blocks. They are also completely compatible with AutoCAD R13.c4 to 2024, and AutoCAD LT95 to LT2024. Future versions also supported. As well brief descriptions have been assigned to the symbols in the sidebar menu, wherever possible.

The symbols are accurately drawn on Layer 0 with a snap value of 0.2 (2.0) and a grid setting of 0.4 (8.0), depending upon the choice of Imperial or (Metric) sized drawing sheets.


Overview of the Electrical Symbol Library

The AutoCAD Electrical Symbol Library includes bells, buzzers, horns, signal lights, capacitors, resistors, disconnects, fuses and circuit breakers along with pressure, limit, float and pull cord switches.

Electrical Blocks also include relay coils, contacts, timers, and a wide range of 1, 2, & 3 pole combination starters are included. Induction and commutator motor symbols, transformers, logic elements and a small selection of solid state devices and a wide range of selector switches, complete with optional cam tables, are provided.

Since the IEC 617 Standard is metric, all the electrical blocks have been drawn to fit on ISO sized drawings. If required, the symbols can be inserted into ANSI sized drawings and then scaled down. Brief descriptions have been assigned to the symbols.
