What this worksheet captures
This worksheet is built to capture the field details that usually decide whether overload relay reset investigation can move into a quote, replacement, or engineering review.
It is meant to keep the intake practical, consistent, and easier to hand off between maintenance, engineering, and purchasing.
- overload model
- motor full-load current
- overload setting
- trip timing or symptoms
- recent process changes
When to use it
Use it when the field information is incomplete, when multiple people are touching the job, or when the replacement path depends on details that are easy to miss over email or phone.
Checklist
Fill this in on-screen or print the page and carry it into the field so the same core details make it back to engineering, sourcing, or quote review.
| Check item | Status | Notes |
|---|---|---|
Overload model Use the label on the installed device and record the exact published model or catalog number. |
||
Motor full-load current Inspect the installed equipment directly and note whether this checkpoint is verified, questionable, or not applicable. |
||
Overload setting Capture the current dial position, trip class, or frame detail exactly as installed before changing anything. |
||
Trip timing or symptoms Describe what the machine is doing in the field, including when the problem occurs and what happens just before the event. |
||
Recent process changes Inspect the installed equipment directly and note whether this checkpoint is verified, questionable, or not applicable. |
How to use it on site
Work from the installed equipment first, then collect the ratings, environment, fit notes, and related components that change the actual buying decision.
| Item | What it means in practice | Why buyers care |
|---|---|---|
| Core role | Protect the motor from sustained overload current | It is not the same as short-circuit protection. |
| What engineers compare first | Current range, trip class, compensation style, and starter fit | Those items decide whether the overload protects the motor correctly. |
| Typical supporting devices | Contactors, disconnects, branch protection, and control reset circuits | The overload works as part of a starter assembly. |
| Common confusion | Treating it like branch short-circuit protection | That confusion leads to the wrong protection strategy. |
What to verify before sending it on
A worksheet is most useful when the captured values are checked for completeness before they move into sourcing or quote prep.
Important verification notes
Use the worksheet to structure the job, then confirm the final release path against the exact product-family data and installed conditions.
