TS 630

TS 630 defines graphical symbols for kind of current, distribution systems, methods of connection, and circuit elements. In electrical diagrams and related technical drawings, symbols are used to show circuit structure without lengthy textual description; this standard belongs to that conventional symbolic language. The metadata also indicates that the standard has been withdrawn and later replaced in practice by TS 11330, TS 11331, TS 11332, TS 11333 and TS 11334.

What the symbol groups represent

The topic groups in this standard reflect the basic distinctions used in electrical notation. Kind-of-current symbols identify whether a system is direct current or alternating current. Distribution-system and method-of-connection symbols show how power is arranged and how circuit connections are made. Circuit-element symbols provide schematic representations of components such as switches, protective devices, sources and loads. In general technical use, these distinctions help drawings remain readable and support consistent interpretation across organizations and projects.

Use in drawings and technical documentation

Graphical-symbol standards support consistent communication in design files, maintenance manuals, training material and troubleshooting documents. In electrical engineering, standardized symbols make it easier to compare wiring diagrams, single-line diagrams and system descriptions. This product record represents a standard that organizes the symbol language for this field; it does not present a test method or numerical performance limit set.
