What it represents
An automatic-trip qualifier indicates that the associated mechanism can operate automatically under its documented condition. An automatic trip describes an operating action initiated by a condition in the device or associated controls. The input that causes tripping may be protective, process-related or another documented trigger.
Show the trip source and resulting contact/device state through the circuit and cross-references. Reset, reclosure and return behaviour remain separate design information.
How to read it
- Identify the initiating protection or process condition in the surrounding circuit.
- Automatic tripping and automatic return describe different parts of the operating sequence.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Identify the initiating protection or process condition in the surrounding circuit.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
Automatic tripping and automatic return describe different parts of the operating sequence.
