## Symbol convention

Convention: IEC
Form: Circuit-breaker function qualifier
Autodesk IEC-60617 Symbol Preview — Operating-device and function qualifiers; vendor family reference, not certified IEC geometry or database identifier.

A breaker-function qualifier identifies automatic interruption capability in the compound representation.

## What it represents

A breaker-function qualifier identifies automatic interruption capability in the compound representation. The function element helps distinguish a breaker from other mechanically similar switching representations. Its associated protection may be shown as integrated releases or through a separately documented relay/trip circuit.
Record the breaker and trip interfaces consistently between the SLD and schematic. The function qualifier cannot replace the trip-unit or protection schedule.

## How to read it

- Identify the actual trip functions and device schedule separately.
- The qualifier does not specify thermal, magnetic or electronic trip details.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Identify the actual trip functions and device schedule separately.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

The qualifier does not specify thermal, magnetic or electronic trip details.
