IEC 60617 - Graphical Symbols for Diagrams

(requires password)

Welcome to the IEC 60617 database

IEC 60617 contains graphical symbols for use in electrotechnical diagrams. All the parts (Ed. 2 or 3) of the previously published IEC 60617 have been incorporated into this database that currently includes some 1900 symbols. The database is the official source of IEC 60617.

Each graphical symbol is identified by a reference number and contains a title (in English and French), a graphical representation in GIF and some additional data as applicable. Some of graphical symbols are available as vectorized EPS format. Various search and navigation facilities allow for easy retrieval of graphical symbols.

Subscriptions and End-User Restrictions

Access to the database is on a subscription basis. Subscriptions can be purchased through the IEC National Committees, National Committee-appointed Sales Outlets, or directly from the
IEC Webstore (simply search for IEC 60617). All subscriptions are subject to the customer agreeing to the IEC Webstore Product(s) Licence Agreement.

Localized versions

In addition to the normative database maintained by TC 3, IEC also hosts localized versions of IEC 60617 maintained under the responsibility of the respective National Committees. The following localized versions are currently available:



The following areas are covered in the database:

  • Conductors and connecting devices
  • Basic passive components
  • Semiconductors and electron tubes
  • Production and conversion of electrical energy
  • Switchgear, controlgear and protective devices
  • Measuring instruments, lamps and signalling devices
  • Telecommunications transmission, switching and peripheral equipment
  • Architectural and topographical installation plans and diagrams
  • Binary logic elements
  • Analogue and hybrid elements

    New metadata and search capability

    The incorporation of the symbols into the database has been accompanied by the addition of a considerable amount of new metadata not present in the previous publication (symbol name, alternative names, keywords, remarks, etc.) and links to related symbols and application notes. The database also provides classified views (by shape, function and application) and a search facility. It is therefore a much richer and more user friendly tool for those who need to understand and apply graphical symbols in electrotechnical diagrams.


    The database is maintained by a validation team appointed by the IEC National Members. Requests for modifications and new symbols are processed via change requests addressed to the validation team by IEC National Committees and TCs.

    National Committees

    National Committees should send a list of staff members who are to be authorized to access the database. The list should include the name and username for each person (username is that currently used to access working documents on the IEC web site). The list should be sent by email to IT Helpdesk.

    TC/SC officers

    IEC TC/SC chairmen and secretaries, as well as PT/WG/MT convenors can request special access from the IEC Central Office by email to IT Helpdesk.
