Westinghouse circuit breaker types?

[Electron_Sam78]

Hey all, I'm looking for a Westinghouse 3 - pole, 20 amp circuit breaker cat no QC3020. I keep getting a result in the search of QC2030H. What's the difference?:?

Sorry the search returns QC3020H

H often is a higher AIC rating, I do not know for certain with that breaker though.

Here is an ebay link to one without the H: http://www.ebay.com/itm/westinghouse-QC-qc3020-qc-20-amp-3-pole-breaker-240v-/281206082356

Google: Cutler Hammer QC3020. The cutler version all seem to have the H on the end, but look the same as the westinghouse QC3020.

This is a lug in + lug out breaker you are looking for correct?

Just wondering if the h version from Cutler Hammer will fit the Westinghouse non-h version

Contact any breaker broker, most any one will be able to supply the breaker. They may also be able to tell you what the H designation means and if it is important.
Be aware Zinsco also had a QC type breaker.
Make sure you are specific that it is the Westinghouse / Cutler brand and NOT a Zinsco.

After some more searching I found a site that had dimensions listed for the CH breaker and they exactly match the Westinghouse. So it looks like it is a good replacement.

Can't say I am familiar with the product in question, but Eaton/Cutler Hammer has acquired the product lines that were under the Westinghouse name in the past - so they are the ones that would have new replacements if they still make them.

Eaton (Cutler Hammer) bought and absorbed that division of Westinghouse decades ago. They are not like them, they ARE the same breakers.

And yes, the H just jeans it has a higher interrupt rating. No problem using a higher rated breaker in a lower application, just not the other way around. They likely stopped making the lower rates because of low volume.

Thanks! Good to know
