TS EN 60617-3

TS EN 60617-3 is the part of the graphical-symbols series for diagrams that focuses on conductors and connecting devices. In electrical and electronic documentation, symbols do more than label parts: they standardise how connections are shown, how continuity is read, and how relationships between elements are interpreted. This part addresses the schematic representation of conductors and connection arrangements.

Why conductors and connecting devices matter in diagrams

GENERAL TECHNICAL CONTEXT: Conductors are the paths that carry electrical current through a circuit, while connecting devices represent terminals, joints, connection points, or similar interfaces where conductors are brought together. In schematic work, the emphasis is on function rather than physical appearance. Clear symbol conventions help distinguish a continuous line from a connection point, crossing, splice, or termination, which is essential for accurate reading of technical drawings.

The symbolic language covered by this part

The symbols covered by this standard help users express how conductors are drawn and how connection arrangements are distinguished in a consistent way. This supports clearer representation of wires, cables, terminals, joints, and related connection features within diagrams. More broadly, it contributes to a common visual language that can be read more consistently across teams and technical contexts.
