A minimum-current relay operates according to a configured low-current condition.

## What it represents

A minimum-current relay operates according to a configured low-current condition. Control drawings must identify whether it supervises an operating load, a permissive or another circuit.

## How to read it

- Check how the relay handles zero current during intentional shutdown.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- Name supervised circuit
- Reference enable condition
- State threshold and delay

## Important distinction

Low current can be an intentional stopped state; the control logic defines when it is abnormal.

## Facts

- Drawing role: Monitoring element
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HCR1F26, VCR1F26 (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
