Seeking Roadtester Applicants for a 3-Phase Circuit Breaker with A High Level of Functionality

rscasny

Greetings to all!

 

I hope everyone is safe and comfortable in these times. If I haven't communicated with you recently, I'll say I (like many others) am working from home. After the initial adjustment, things now are running pretty much the way they were. I will be launching more roadtests in the coming weeks.

 

Today, I wanted to discuss with you about an opportunity I have for the RoadTest Program.

 

I have a supplier who would like a 3-Phase Circuit Breaker roadtested. Now, this isn't your typical thermo-magnetic, molded-case circuit breaker. It possesses an add-on module that gives it a lot of functionality and the ability to monitor circuit breaker health, as well as the ability to send to to the Internet (if configured for that capability).

 

Here's the information page on the breaker:

 

https://www.eaton.com/us/en-us/catalog/electrical-circuit-protection/power-defense-molded-case-circuit-breakers.html

When the add-on module (call a trip unit) is attached it has a lot of functionality.

 

So, to the roadtest....

 

This is a 3-phase breaker. I believe the product line is rated between 15A and 250A, and up to 600VAC.  Needless to say, it's used primarily for 3-phase inductor motors, in factories, industrial facilities, some labs, etc.

 

What would be nice for a roadtest is to compare this breaker to a standard thermo-mag, molded case breaker. The roadtest is really the functionality added by the trip unit.

 

the other issue is what frame size to use. Perhaps different roadtesters would need different frame sizes.....

 

Clearly, this requires a particular kind of roadtester.

 

If you feel you are interested and fit my requirements, please leave a comment or message me at rscasny

    I have an Eaton Cutler Hammer WMS3D32 415V 32AMP It's small frame DIN rail mounted, I could switch out, that runs a 25HP pump motor. There's not a lot of room for extra "stuff" though

    Thanks for the heads up Gough Lui ......... I can certainly test and inspect three phase breakers and compare them to other models. Eaton are not widely used in my industry sector in the UK, so it would…

    Hi Donald, Thanks for this long and detailed post. We would send you the frame size that fits for you. And we would send you an electronic trip unit as well, to give you added functionality. It might be…

    That's an interesting device - but it's a shame that I don't quite have the chops to give it a go.

     

    But when I saw this - the first person I thought of was three-phase - perhaps this might be up your alley?
