Understand the difference.

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

ANSI/IEEE late-break normally-closed contact symbol

The delayed NC contact form identifies opening later in a specified contact sequence. The circuit reader needs to understand the path that remains continuous while other associated contacts have already changed state.

Form evidence
Autodesk IEEE-oriented Relays and Contacts 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 mechanical late-break contact and an off-delay timer output can serve different timing arrangements.

Late-break normally-closed contact

A late-break NC contact opens later in the documented operating sequence than specified associated contacts. The function requires a common-device reference and a sequence description.

A distinction that matters

A late-break contact and an off-delay contact achieve delay by different mechanisms.
