Understand the difference.

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

SHUNT

IEEE / ANSI

ANSI/IEEE current-measuring shunt symbol

The shunt form identifies a resistive current path used to derive a voltage measurement. Power-current terminals and voltage-sense leads must be distinguished where the actual device provides separate sensing connections.

Form evidence

Autodesk IEEE-oriented Resistive Components functional form. Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

A shunt produces a measured voltage drop; a CT provides an instrument-transformer secondary current.

Current-measuring shunt

A current-measuring shunt produces a documented voltage drop corresponding to current through a resistive element. The drawing must distinguish the current path from the sensing leads.

A distinction that matters

A shunt produces a voltage measurement without a current-transformer secondary.
