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.

CAP 3PH

Symbols

Three-phase power-factor capacitor

A three-phase capacitor assembly provides a documented reactive-power function connected to the power circuit. The schematic needs its connection, switching and protective devices as separate elements.

Drawing use: SLD / Schematic
Application: Power distribution
Reference family: IEC / Manufacturer

A distinction that matters

A power-factor capacitor is a power-circuit assembly, not a generic small-signal filter capacitor.

Symbols

Resistor

A resistor representation identifies a resistive component in a circuit. Different drawing conventions can use different basic outlines, while additional qualifiers distinguish variable resistors, shunts or heating elements. The value, rating and purpose are separate annotations.

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

A distinction that matters

IEC-style rectangular and other conventional resistor depictions can describe the same component concept, but qualifiers and documentation still matter.
