What this worksheet captures
This worksheet is built to capture the field details that usually decide whether contactor coil identification 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.
- contactor model number
- coil label or code
- coil voltage shown
- frequency if marked
- where the coil is installed
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.
Worksheet
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.
| Field | Value | Notes |
|---|---|---|
Contactor model number Use the label on the installed device and record the exact published model or catalog number. |
Manufacturer / Family
Catalog / Model
Series / Rev

|
Coil label or code Read the coil sticker, tag, or molded marking directly from the contactor coil and copy what is actually printed there. |
||
Coil voltage shown Read the coil sticker, tag, or molded marking directly from the contactor coil and copy what is actually printed there. |
Value

|
Frequency if marked Read the coil sticker, tag, or molded marking directly from the contactor coil and copy what is actually printed there. |

Where the coil is installed Capture the exact field detail from the installed equipment, drawings, labels, or documentation that best answers this part of the job. |
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.
