ANSI/IEEE Minimum-current monitoring relay form
IEEE-library form of minimum-current monitoring relay: a minimum-current relay operates according to a configured low-current condition.
In plain English
What does ANSI/IEEE Minimum-current monitoring relay form mean?
This reference locates minimum-current monitoring relay in Autodesk's IEEE-oriented current protection relays family. 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. The public library uses HCR1F26 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Trace the measured quantity or initiating control signal separately from the output contacts. The device tag links the sensing or operating element to the controlled circuit; settings, reset behaviour and the actual terminal arrangement belong in the selected equipment documentation.
What the drawings help you do
Check how the relay handles zero current during intentional shutdown. Low current can be an intentional stopped state; the control logic defines when it is abnormal. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

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