Identifies the documented air-magnetic interruption construction on a legacy or selected breaker drawing.

## In plain English

### What this block does

Identifies the documented air-magnetic interruption construction on a legacy or selected breaker drawing.

### A simple example

In a medium-voltage switchgear drawing, the operating reference helps the reader distinguish the interrupting device from its isolation, earthing and auxiliary-control interfaces. For this reference, the drawing identifies “Power circuit and trip release” at the input and “Air-magnetic interrupted path” at the output. The drawing does not establish replacement compatibility.

### What the drawings help you do

Start at the named input: Power circuit and trip release. Identify its source device or document and the state represented on the drawing. Follow the named output: Air-magnetic interrupted path. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: Power circuit and trip release
- Output: Air-magnetic interrupted path
- Application reference: An explanation of a named drawing function or circuit relationship; the project documents define the equipment and its connections.

## What it represents

Identifies the documented air-magnetic interruption construction on a legacy or selected breaker drawing. A switching-device operating reference adds the specific mechanism or duty context needed to interpret its place in a power circuit. The same basic switching outline can serve different equipment constructions, so the added description must remain attached to its device tag.
In a medium-voltage switchgear drawing, the operating reference helps the reader distinguish the interrupting device from its isolation, earthing and auxiliary-control interfaces. For this reference, the drawing identifies “Power circuit and trip release” at the input and “Air-magnetic interrupted path” at the output. The drawing does not establish replacement compatibility.
Use the device schedule for its actual construction, operating duty and ratings. These original functional illustrations describe the named role and do not certify a standard glyph or product footprint. The functional block is an independent explanation of this named application. Equipment-specific ratings, terminal connections and operating conditions must be established in the project documentation.

## How to read it

- Start at the named input: Power circuit and trip release. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Air-magnetic interrupted path. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- The drawing does not establish replacement compatibility.
- Use the device schedule for its actual construction, operating duty and ratings. These original functional illustrations describe the named role and do not certify a standard glyph or product footprint.

## Information to show or reference

- Label the source and connection reference for power circuit and trip release.
- Identify the destination and defined state of air-magnetic interrupted path.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: The drawing does not establish replacement compatibility.

## Important distinction

The drawing does not establish replacement compatibility. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.

## Facts

- Representation: Functional block
- Installation focus: Switchgear
