Understand the difference.

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

IEEE / ANSI

ANSI/IEEE Maximum-current monitoring relay form

This reference locates maximum-current monitoring relay in Autodesk's IEEE-oriented current protection relays family. A maximum-current relay changes its output when the measured current meets a configured high-current condition. Its schematic separates measurement, auxiliary power and relay outputs. The public library uses HCR1F25 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

Form evidence

Maximum Current Protection. Autodesk IEEE Symbol Preview: Current Protection Relays, block HCR1F25. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier.

A distinction that matters

A maximum-current monitoring element is not a complete feeder protection scheme by itself.
