What this worksheet captures
This worksheet is built to capture the field details that usually decide whether contactor replacement verification 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.
- original part number
- application description
- ratings
- mechanical fit notes
- accessory details
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 |
|---|---|---|
Original part number Use the installed part label, nameplate, or BOM and record the full catalog number without shortening it. |
||
Application description Describe what the machine or circuit is doing in normal operation so the replacement is judged against the real job. |
||
Ratings Capture the exact family, ratings, fit details, and accessories that the next part still has to match. |
||
Mechanical fit notes Capture the exact family, ratings, fit details, and accessories that the next part still has to match. |
||
Accessory details Capture the exact family, ratings, fit details, and accessories that the next part still has to match. |
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 | Switch a power circuit from a separate control signal | This explains why it belongs on the power side instead of the light control side. |
| What engineers compare first | load type, horsepower or current, coil voltage, and accessory needs | These are the checks that keep replacements honest. |
| Typical supporting parts | overload relays, auxiliaries, suppressors, and starter hardware | Contactors rarely live alone in real panels. |
| Common confusion | Treating it like a complete starter or like a small relay | That leads to the wrong expectations on protection and duty. |
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.
