Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

K CAP

Symbols

Relay coil with capacitor suppression

A relay with a capacitor suppression element includes a documented capacitive network associated with the coil. Its connection and effect on switching are product-dependent.

Drawing use: Schematic
Application: Control circuits
Reference family: IEC / Manufacturer

A distinction that matters

Capacitor suppression is different from the coil's operating function and from a motor run capacitor.

Coil

Symbols

Relay coil

A relay coil represents an operating element that changes the state of associated contacts when the device operates. Coil and contact representations are often drawn in different locations to make the circuit easier to read. Their shared identifier and cross-references establish the relationship.

Drawing use: Schematic
Application: Control circuits
Reference family: IEC / IEEE / ANSI

A distinction that matters

A relay coil is not a contactor power pole. Similar operating-element marks can represent equipment with different switching duties.
